A cordless chainsaw trades gas, exhaust, and extension cords for battery-powered cutting, but the right choice depends on the size and frequency of your jobs. My best overall pick is the EGO POWER+ 16-inch, which pairs a longer bar with a 56V battery and charger for a more capable general-purpose setup. The Greenworks 40V 12-inch is a more compact option with a battery and charger included, while the SEESII 40V 18-inch stands out for buyers who want a larger bar and two batteries. The main tradeoffs are cutting reach versus weight, included battery capacity versus runtime, and a familiar tool-battery platform versus a standalone kit. Read on for the full breakdown and guidance on matching a cordless saw to your work.

Key Takeaways
- The EGO POWER+ 16-inch is the clearest all-rounder in this lineup: it includes a 56V battery and charger, while several other full-size options require buyers to check whether batteries are included.
- Bar length divides the lineup more than brand names do. The 6- to 8-inch models suit pruning and small limbs; 10- to 12-inch saws cover lighter cutting; 16- to 18-inch models target larger work but demand more careful handling.
- The SEESII 40V 18-inch kit has the most conspicuous runtime-oriented bundle among the listed larger saws, with two 5.0Ah batteries, though a longer bar and extra battery do not remove the need to match the saw to the wood.
- Battery compatibility is a buying decision, not a minor spec. The BLACK+DECKER is tool-only, and the DeWalt-compatible models make the most sense when a buyer already owns compatible batteries or has verified the kit details.
- Small cordless saws are not interchangeable with full-size saws. Dual-bar mini models and compact 6-inch picks prioritize reach into pruning tasks and easy handling, not repeated cuts through large-diameter logs.

More Details on Our Top Picks
SEESII 12-Inch Electric Chainsaw Cordless, Brushless Motor
The SEESII is a strong fit for buyers who want a cordless saw with a 12-inch bar and a spare battery ready for the next round of cutting. Its two 4.0Ah batteries give it a runtime advantage over the Greenworks 40V 12-inch, which includes a single 2.0Ah battery. The 1200W brushless motor and automatic oiling are aimed at more sustained yard work, while tool-free chain tensioning makes adjustments less of a chore. The tradeoff is weight: at about 12 lb, it is heavier than the Greenworks and far less nimble than the 3.2 lb mini saw with interchangeable bars. I’d choose this for repeated branch and log cutting, but not for overhead pruning or buyers who prioritize easy handling above battery capacity.
Pros:- Two 4.0Ah batteries provide more included capacity than the Greenworks 12-inch model’s single 2.0Ah battery.
- 12-inch bar suits a broader range of yard cuts than the 6-inch mini saws.
- 1200W brushless motor is specified for demanding cutting work.
- Automatic oiling and tool-free chain tensioning reduce routine interruptions.
Cons:- Listed weight of 12 lb is high for a cordless saw in this group.
- A 12-inch bar is less suited to tight spaces and delicate pruning than compact mini saws.
- The provided product data does not specify battery voltage or runtime.
Best for: Homeowners who regularly cut branches, storm debris, and moderate-size logs and want two included batteries for longer work sessions.
Not ideal for: Buyers who need a lightweight saw for overhead pruning or frequent one-handed maneuvering; its listed 12 lb weight can make extended handling tiring.
- Power source:Battery powered
- Motor:1200W brushless
- Bar length:12 inches
- Batteries included:2
- Battery capacity:4.0Ah each
- Weight:12 lb (listed)
- Oil tank capacity:60mL
- Chain tensioning:Tool-free
Our verdict“Choose the SEESII if you want a 12-inch cordless saw with two large-capacity batteries for repeated yard cutting and can accept the added weight.”
Greenworks 40V 12-inch Cordless Electric Chainsaw with 2.0 Ah Battery and Charger
The Greenworks makes more sense as a manageable, straightforward yard saw than as a choice for long, demanding cuts. At 10.9 lb, it is lighter than the SEESII 12-inch, and the 40V battery is part of a wider Greenworks battery ecosystem; the supplied battery can also charge phones and tablets. Its dual safety start and tool-free auto-tensioning suit occasional pruning and cleanup without adding much setup. The main limitation is the included 2.0Ah battery: compared with the SEESII’s two 4.0Ah packs, it offers less battery capacity for extended work, and the 12-inch bar is not meant for large trunks. I’d pick it for light-to-moderate jobs and compatible-tool owners, but choose a higher-capacity setup for repeated heavy cutting.
Pros:- 40V platform can be useful to buyers who already own compatible Greenworks tools.
- Lighter listed weight than the SEESII 12-inch.
- Dual safety start and tool-free auto-tensioning simplify use and chain adjustment.
- Included battery can also charge phones and tablets.
Cons:- Single 2.0Ah battery is a weaker fit for extended cutting than two-battery packages.
- 12-inch bar is not suited to larger trunks or heavy-duty cutting.
- Regular chain and saw maintenance is still required.
Best for: Greenworks battery-system owners who want a lighter 12-inch saw for periodic pruning, yard cleanup, and small storm-damage jobs.
Not ideal for: People cutting large logs or working for long stretches away from a charger; the single 2.0Ah battery limits capacity compared with the SEESII 12-inch package.
- Model number:CS40B210
- Battery voltage:40V
- Battery capacity:2.0Ah
- Bar length:12 inches
- Weight:10.9 lb
- Included components:Chainsaw, battery, charger, manual
- Safety and adjustment:Dual safety start; tool-free auto-tensioning
- Warranty:3 years
Our verdict“Choose the Greenworks for manageable, occasional yard work if its 40V battery platform suits your other tools, not for sustained heavy cutting.”
12″ Electric Chainsaw Cordless, 20V Battery Powered Cordless Chain Saw, Chainsaw with 2 x 4.0Ah Lithium ion Battery and Charger for Wood Cutting, Tree Saw Trimming and Branch Pruning
This 12-inch saw pairs a relatively compact listed weight with two 4.0Ah batteries, making it a capacity-focused option for buyers who do not want to stop after one pack. Its stated 10 m/s chain speed, automatic oiling, and dial-based tool-free tension adjustment give it a fuller feature set than the simpler Greenworks 40V 12-inch. The safety lock and hand guard add practical protections, though they do not replace careful chainsaw handling. The product description also lists a 2.56 hp engine and a 12,000 RPM figure, while the supplied specs separately identify 1200W; those claims are not directly comparable without more detail. At 3.71 kg, it is easier to carry than the SEESII 12-inch’s listed 12 lb, but buyers should weigh that against the unclear relationship between its stated power figures.
Pros:- Two 4.0Ah batteries provide substantial included battery capacity.
- 12-inch bar covers more than the 6- and 8-inch mini saws.
- Automatic oiling and dial-based tool-free tension adjustment support easier upkeep.
- Safety hand guard and two-step start add useful operating safeguards.
Cons:- Product information gives multiple power figures without clarifying how they relate.
- Battery voltage and runtime are not specified in the supplied data.
- A 12-inch saw is bulkier for fine pruning than compact handheld models.
Best for: Homeowners who want a 12-inch cordless saw with two 4.0Ah batteries, automatic lubrication, and tool-free chain adjustment for mixed pruning and log-cutting chores.
Not ideal for: Buyers who need clearly documented power and runtime figures or prefer an established battery platform; the available product data does not identify the battery voltage or runtime.
- Bar length:12 inches
- Power figure:1200W listed in supplied specs
- Additional motor claims:2.56 hp; 12,000 RPM
- Chain speed:Up to 10 m/s
- Batteries included:2
- Battery capacity:4.0Ah each
- Weight:3.71 kg
- Oil tank capacity:0.15 qt (140mL)
- Chain adjustment:Tool-free dial
Our verdict“Pick this model for its two-battery 12-inch package and easy adjustments, while treating its conflicting power claims cautiously.”
Mini Chainsaw Cordless, 8 Inch & 6 Inch Electric Chainsaw with 2 Batteries, 1000W Brushless Motor
The interchangeable 6-inch and 8-inch bars are the reason to choose this mini saw: the shorter setup is easier to guide among branches, while the longer one gives more reach for modestly thicker wood. At a listed 3.2 lb, it is far easier to handle than the 12-inch SEESII or Greenworks saws, though it gives up their longer bar reach for larger logs. The package includes two 2000mAh batteries and lists up to 60 minutes of runtime, but that figure may vary with cutting load. Its 1000W brushless motor sounds capable for small-to-medium jobs, not a substitute for a full-size saw. One practical snag: the 30mL oil tank is small, and oil is not included according to the product information. I’d favor it for pruning versatility, not firewood processing.
Pros:- Interchangeable 6- and 8-inch bars adapt to different pruning tasks.
- Listed 3.2 lb weight is substantially lighter than the 12-inch saws in this roundup.
- Two 2000mAh batteries are included.
- Brushless motor and listed runtime of up to 60 minutes suit routine garden work.
Cons:- Small bar sizes are not suited to large logs or heavy cutting.
- Lubricating oil is not included, according to the product information.
- 30mL oil tank requires more frequent attention than larger-tank models.
Best for: Gardeners and homeowners who prune varied branch sizes and want a light saw with two bar lengths for tighter and slightly larger cuts.
Not ideal for: Buyers processing large logs or seeking a full-size replacement; its 6- and 8-inch bars limit cutting reach and sustained capacity.
- Motor power:1000W brushless
- Guide bar sizes:6 inches and 8 inches
- Batteries:2 × 2000mAh
- Listed runtime:Up to 60 minutes
- Weight:3.2 lb
- Oil tank capacity:30mL
- Safety features:Safety lock and protective gear included
Our verdict“Choose this mini saw for lightweight, adaptable pruning across small branches, and skip it if your regular work involves thick logs.”
Mini Cordless Chainsaw 6 Inch – Battery Powered, Lightweight, Handheld for Wood and Tree Trimming
This 6-inch mini chainsaw is the simplest fit here for small, routine trimming: at 3.3 lb, it is easy to carry between garden tasks, and its auto oiler reduces the need to manually lubricate the chain during work. Unlike the two-bar mini saw, it does not offer an 8-inch option, so it is less adaptable when branches get thicker. Its 880W motor and 2000mAh battery are aimed at pruning and DIY cuts rather than extended log work. The listed security lock, baffles, and anti-slip handle add useful safeguards and grip, but they do not change the saw’s limited 6-inch cutting capacity. I’d choose it for occasional branch cleanup when portability matters more than reach; for broader pruning flexibility, the 6- and 8-inch mini model is the better match.
Pros:- Lightweight listed design at 3.3 lb is convenient for short pruning sessions.
- Auto-oiler supports chain lubrication during cutting.
- Security lock, safety baffles, and anti-slip handle provide practical safety and grip features.
- Rechargeable battery avoids cord management around the garden.
Cons:- 6-inch cutting capacity restricts it to smaller branches and light jobs.
- Listed 2000mAh battery capacity may limit longer work sessions.
- Lubricating oil is not included, according to the product information.
Best for: Homeowners who need a compact cordless saw for occasional garden pruning, small branches, and light DIY wood cutting.
Not ideal for: People who routinely cut thicker limbs, larger logs, or need more than a 6-inch bar; the interchangeable-bar mini model offers greater reach.
- Motor power:880W
- Bar length:6 inches
- Battery capacity:2000mAh
- Weight:3.3 lb
- Chain material:Manganese steel
- Oiling:Automatic oiler
- Safety features:Security lock, safety baffles, anti-slip handle
- Warranty:365 days
Our verdict“Choose this 6-inch model for light, occasional pruning where low weight matters more than cutting reach or extended runtime.”
BLACK+DECKER 20V MAX Cordless Chainsaw, 10-Inch (Tool Only)
I’d choose the BLACK+DECKER 20V MAX for light yard work where easy handling matters more than cutting capacity. Its 10-inch bar and stated 8-inch cut capacity suit pruning and smaller wood, while tool-free tensioning makes routine chain adjustments simpler. Compared with the SEESII 40V 16-Inch, this is a more compact, less ambitious option; it is not the pick for regular firewood cutting or larger limbs. At 7.6 pounds, it is manageable for occasional jobs, though the listed weight is heavier than some handheld mini saws. The main catch is the bare-tool format: you’ll need a compatible 20V MAX battery and charger, which changes the value calculation if you don’t already own them. I’d skip it for buyers who need longer reach through thicker wood.
Pros:- Tool-free chain tensioning allows quick adjustments
- 10-inch bar suits pruning and smaller cutting tasks
- Cordless 20V platform avoids extension cords
- Lighter-duty format is easier to maneuver than the 16-inch SEESII
Cons:- Battery and charger are not included
- Stated cut capacity is limited to 8 inches
- At 7.6 pounds, it is not as light as compact handheld mini saws
Best for: Homeowners with an existing BLACK+DECKER 20V MAX battery who need a manageable saw for pruning and small wood-cutting jobs
Not ideal for: Buyers cutting larger logs or seeking a ready-to-use kit, since capacity is limited and the battery and charger are separate
- Model:LCS1020B
- Battery voltage:20V
- Bar length:10 inches
- Cut capacity:8 inches
- Item weight:7.6 pounds
- Chain length:10 inches
- Battery and charger:Sold separately
Our verdict“Choose this bare tool for occasional pruning if you already own a BLACK+DECKER 20V MAX battery and do not need to cut beyond 8 inches.”
SEESII 40V Cordless Electric Chainsaw, 16 Inch
The SEESII 40V 16-Inch is the more capable fit here for routine firewood, tree trimming, and larger DIY cuts. Its 2000W brushless motor and 16-inch bar give it more reach than the BLACK+DECKER 20V MAX, while two 4.0Ah batteries are listed for up to 90 minutes of runtime. That longer-cutting setup brings more weight: at 10.3 pounds with a battery, it is less appealing for overhead pruning or extended one-handed work than the 3.2-pound SEESII mini saw. Automatic oiling and tool-free tensioning reduce maintenance interruptions, but the product data is inconsistent about whether batteries and a charger are included, so I’d verify package contents before buying. It also isn’t positioned as a professional-duty saw; frequent heavy work calls for a more purpose-built option.
Pros:- 16-inch guide bar offers more reach than the mini saws in this group
- 2000W brushless motor is suited to substantial household cutting tasks
- Automatic chain oiling reduces manual lubrication work
- Listed runtime is up to 90 minutes with dual batteries
Cons:- At 10.3 pounds with battery, it can tire users during overhead work
- Product details conflict on whether batteries and charger are included
- Not presented as a professional heavy-duty saw
Best for: Homeowners who regularly cut firewood or handle larger yard projects and want a 16-inch cordless saw with listed dual-battery runtime
Not ideal for: Buyers focused on lightweight overhead pruning or professional heavy-duty cutting, because this is a heavier consumer-oriented saw
- Voltage:40V
- Motor:2000W brushless
- Guide bar length:16 inches
- Battery configuration:2 × 40V 4.0Ah batteries listed
- Runtime:Up to 90 minutes
- Weight:10.3 pounds with battery
- Chain oil capacity:150 ml
- Chain maintenance:Automatic oiling and tool-free tensioning
Our verdict“Pick the SEESII 40V for household firewood and larger cuts if you can confirm the battery package and are comfortable with its added weight.”
EGO POWER+ 16” Battery Powered Chainsaw, Cordless, Includes 56V 2.5Ah Battery and Charger
I’d put the EGO POWER+ 16-inch ahead of the SEESII 40V when a buyer wants a clearly specified battery-and-charger kit rather than sorting out a bare tool. Its 56V brushless system is described as delivering performance equivalent to a 40cc gas chainsaw, and the 16-inch bar gives it the same broad class of cutting reach as the SEESII. The included 2.5Ah battery makes setup more straightforward, but its capacity may limit long sessions compared with the SEESII’s listed dual 4.0Ah batteries. At 9 pounds, it is lighter than that SEESII with battery, though still substantial for prolonged overhead use. Tool-free tensioning, automatic oiling, and weather-resistant construction add practical convenience; I’d choose another option for featherweight pruning or extended cutting without charging breaks.
Pros:- Includes a 56V 2.5Ah battery and charger
- Brushless motor is specified as equivalent to a 40cc gas chainsaw
- Tool-free chain tensioning and automatic oiling simplify upkeep
- Weather-resistant construction suits outdoor work
Cons:- 2.5Ah battery may constrain longer cutting sessions
- At 9 pounds, it can be tiring for prolonged overhead use
- Requires charging before another extended session
Best for: Homeowners who want a ready-to-use 16-inch cordless saw for yard work and occasional firewood, with battery and charger included
Not ideal for: Users planning long, uninterrupted cutting sessions or extended overhead pruning, given the 2.5Ah battery and 9-pound weight
- Battery voltage:56V
- Battery capacity:2.5Ah
- Bar length:16 inches
- Chain speed:20 m/s
- Weight:9 pounds
- Chain pitch:3/8 inch
- Chain gauge:.043 inch
- Included:Battery and charger
Our verdict“Choose the EGO kit if you want a supplied battery and charger with 16-inch cutting reach, and can work within the runtime of a 2.5Ah battery.”
12 Inch Cordless Mini Chainsaw for DeWalt 20V Max Battery, 1000W Brushless Electric Chainsaw with Dual Safety Lock
This 12-inch brushless mini chainsaw makes the most sense for buyers already invested in DeWalt 20V MAX batteries. At 4.5 pounds, it offers a longer bar and more cutting reach than the 3.2-pound SEESII mini saw, while remaining far easier to carry than the 16-inch EGO or SEESII models. The 1000W motor, automatic oiling, and dual safety lock support general trimming and DIY cuts without stepping up to a full-size saw. Its tradeoff is the platform-specific fit: batteries and charger are not included, and the stated compatibility is with DeWalt 20V MAX batteries. The supplied data also flags chain tension loosening with heat, so manual checks may interrupt work. I’d favor it over the BLACK+DECKER for added bar length only if you already have the matching battery system.
Pros:- Compatible with DeWalt 20V MAX batteries
- 12-inch bar provides more reach than the BLACK+DECKER 10-inch model
- 4.5-pound weight is manageable for portable yard work
- Automatic oiling and dual safety lock are included
Cons:- Battery and charger are not included
- Chain tension may loosen as the saw heats up and need manual adjustment
- 12-inch bar limits its suitability for larger logs
Best for: DeWalt 20V MAX battery owners who want a lightweight saw for trimming, DIY wood cutting, and small-to-medium branches
Not ideal for: Buyers without DeWalt batteries or those tackling larger logs and long cutting sessions, since the kit excludes power components and the bar is 12 inches
- Battery compatibility:DeWalt 20V MAX batteries
- Motor power:1000W
- Motor type:Brushless
- Bar length:12 inches
- Weight:4.5 pounds
- Oil tank capacity:100 ml
- Safety feature:Dual safety lock
- Included accessories:2 chains, 1 guide bar, goggles, and gloves
Our verdict“Choose this compact saw if you own DeWalt 20V MAX batteries and need more reach than a small pruning saw without moving to a full-size model.”
SEESII 8 Inch & 6 Inch Mini Cordless Chainsaw with 2 Batteries and Auto Oiler
For small-property pruning, the SEESII two-bar mini chainsaw prioritizes light handling and flexibility over reach. At 3.2 pounds, it is the easiest option here to maneuver for quick trimming, and its 6-inch and 8-inch bars let buyers match the setup to smaller branches or somewhat larger cuts. That makes it more adaptable than the BLACK+DECKER’s single 10-inch bar, but it is not a substitute for the 16-inch EGO when firewood or larger logs are on the agenda. Two 2000mAh batteries are included, which helps keep basic yard work moving, though the capacity may not satisfy extended cutting. The brushless motor and self-oiler add convenience, but the oil tank needs attention and the chain adjustment may take some practice. I’d pick it for light, frequent trimming—not as a primary saw for demanding work.
Pros:- Two bar sizes provide flexibility for smaller trimming tasks
- 3.2-pound weight supports easier maneuvering
- Includes two 2000mAh batteries
- Brushless motor and automatic oiling reduce routine effort
Cons:- Short bars limit cutting reach and capacity
- Battery capacity may fall short for prolonged cutting
- Oil requires refilling and chain adjustment may take practice
Best for: Gardeners and homeowners who mainly prune branches and want a very light saw with two bar sizes and batteries included
Not ideal for: People cutting firewood, large logs, or substantial branches, since both bars are short and the batteries are modest in capacity
- Guide bar sizes:6 inches and 8 inches
- Motor:1000W brushless
- Battery configuration:2 × 2000mAh batteries
- Weight:3.2 pounds
- Oiling:Automatic self-oiler
- Chain tension adjustment:Easy adjustment
- Safety features:Security switch and flip mechanism
- Included safety gear:Goggles and gloves
Our verdict“Pick this SEESII kit for light pruning where low weight and interchangeable 6-inch and 8-inch bars matter more than cutting capacity.”
Seesii Mini Chainsaw, 6-inch Mini Chainsaw Cordless, Handheld Electric Power Chain Saw with 2 Batteries
I’d choose this 6-inch, 2.7-pound saw for pruning and small-diameter cuts where a full-size cordless chainsaw would feel cumbersome. Its compact bar and one-handed format favor control around shrubs and branches, while the included two 21V 2.0Ah batteries give you a spare to swap in. Compared with the larger SEESII 8-inch Mini Chainsaw, this model is easier to maneuver in tight spaces but has less reach and cutting capacity. The listing claims a 900W motor and chain speeds up to 30 ft/s, though those figures don’t make a six-inch saw a substitute for a standard saw on large logs. You’ll also need to supply bar oil: the kit includes an oil bottle, but oil is not included.
Pros:- Light 2.7-pound design is easier to maneuver for brief pruning jobs
- Includes two 21V 2.0Ah batteries and a charger
- Compact six-inch bar suits tight spaces and small branches
- Double safety lock and chain guard are listed safety features
Cons:- Six-inch cutting capacity limits the size of work it can handle
- Bar oil is not included, despite the supplied oil bottle
- The listed 80–100 minutes of operation is not tied to a specific cutting workload
Best for: Home gardeners and occasional users who need a lightweight saw for pruning branches and cutting small pieces of wood.
Not ideal for: People regularly cutting thick logs or felling trees; its six-inch bar and handheld format are aimed at light work.
- Bar length:6 inches
- Motor power:900W
- Chain speed:Up to 30 ft/s (listing also specifies 29 ft/s)
- Battery:2 x 21V 2.0Ah
- Weight:2.7 lb (also listed as 1 kg)
- Claimed runtime:80–100 minutes
- Included items:Two batteries, two chains, charger, oil bottle, gloves, nut driver, screwdriver
Our verdict“Pick this Seesii for light pruning and portability, not for the larger cuts handled by an eight-inch or full-size cordless saw.”
10 Inch Cordless Chainsaw for DEWALT 20V MAX Battery, 1000W Brushless Handheld Chainsaw
This 10-inch brushless saw makes the most sense for someone already invested in compatible DEWALT 20V MAX batteries. The platform compatibility can reduce the need to manage another battery system, and the kit listing says it includes a 4.0Ah battery and charger for buyers starting from scratch. A self-oiling system, visible oil tank, and battery indicator add useful feedback during routine cutting. Against the six-inch Seesii Mini Chainsaw, its longer bar offers more reach for yard debris; compared with the 16-inch cordless models in this roundup, it’s more compact but less suited to large logs. The listed weight is four pounds, but the product data doesn’t clarify whether that includes the battery. I’d also verify fit with your exact battery before relying on compatibility.
Pros:- Compatible with a broad list of DEWALT 20V MAX batteries
- Brushless motor is designed for efficient operation
- Self-oiling system and clear tank support routine chain maintenance
- Battery indicator gives a quick charge-status check
Cons:- 10-inch bar is less suited to large logs than the 16- and 18-inch options
- Listed four-pound weight does not specify whether the battery is included in that figure
- Compatibility claims should be checked against the buyer’s specific battery
Best for: DEWALT 20V MAX tool owners who want a compact chainsaw for pruning and smaller yard-cutting jobs.
Not ideal for: Buyers who need a long bar for large logs, or who want a clearly documented weight and battery configuration before purchase.
- Bar length:10 inches
- Motor power:1000W
- Motor type:Brushless
- Battery platform:DEWALT 20V MAX compatible
- Included battery:4.0Ah
- Weight:4 lb (battery inclusion not specified)
- Oiling:Automatic self-oiling system with see-through tank
- Warranty:12 months
Our verdict“Choose this if DEWALT 20V MAX compatibility and a compact 10-inch bar matter more than full-size cutting reach.”
SEESII 40V Electric Chainsaw Cordless 18-Inch with 2 x 5.0Ah Batteries
Among these five picks, this is the one I’d reserve for substantial property work: its 18-inch bar and 40V system give it more reach than the 16-inch, 40V model, while the two 5.0Ah batteries are supplied for extended cutting sessions. The manufacturer claims up to 200 cuts on four-inch softwood, a useful reference point but not a promise for dense hardwood or every job. Its 2200W brushless motor, automatic oiling, and tool-free tensioning are aimed at reducing interruptions, although setup is still required. Compared with the compact Seesii six-inch saw, this is a different class of tool and much better suited to larger logs; the tradeoff is more bulk and a greater need for careful handling. I’d skip it for occasional light pruning.
Pros:- 18-inch guide bar provides more reach than the 16-inch cordless option
- Includes two 40V 5.0Ah batteries and two fast chargers
- Automatic oiling and tool-free chain tensioning simplify routine upkeep
- Emergency brake and dual-action safety switch are listed safety features
Cons:- Larger bar and higher-power setup are excessive for light pruning
- Requires initial installation and chain setup
- Claimed cut count is based on four-inch softwood and may not reflect tougher work
Best for: Property owners who regularly cut larger logs, clear substantial storm debris, or need an 18-inch cordless bar with two included batteries.
Not ideal for: Gardeners seeking a small, easily stored pruning saw or users whose work is limited to thin branches.
- Guide bar length:18 inches
- Motor power:2200W brushless
- Voltage:40V
- Batteries:2 x 5.0Ah
- Chain speed:30 ft/s
- Weight:8.6 lb with both batteries
- Oil tank capacity:80 ml
- Claimed cutting output:Up to 200 cuts on 4-inch softwood per full charge
Our verdict“Choose this SEESII for demanding cordless property cutting where an 18-inch bar and two large batteries justify the added size.”
16 Inch Cordless Electric Chainsaw with 2000W Brushless Motor, 40V Battery & Fast Charger
This 16-inch, 40V chainsaw sits between compact pruning saws and the more reach-focused 18-inch SEESII. Its 2000W brushless motor and 35 ft/s chain speed are paired with a 4.0Ah battery, making it a reasonable fit for general yard cutting when a mini saw would be undersized. The 150ml oil reservoir is larger than the 80ml tank listed for the SEESII 18-inch model, so it may mean fewer oil top-ups between checks, though usage affects that. Automatic lubrication and tool-free tension adjustment reduce routine fuss; the tradeoff is that the included 4.0Ah battery has less stated capacity than the SEESII’s two 5.0Ah packs. Its listed runtime is up to 50 minutes, but actual cutting time will vary, and this saw may feel heavy for prolonged one-handed work.
Pros:- 16-inch bar offers more reach than the mini chainsaws in this group
- 2000W brushless motor and 35 ft/s chain speed are suited to demanding yard work
- Automatic lubrication and tool-free tension adjustment simplify maintenance
- Includes a 40V battery and fast charger
Cons:- Single 4.0Ah battery has less listed capacity than the two 5.0Ah batteries included with the 18-inch SEESII
- Listed runtime of up to 50 minutes varies with workload
- Description notes that the saw can feel heavy during prolonged one-handed use

Our verdict“Pick this 16-inch model for a middle ground between compact saws and the larger 18-inch SEESII, accepting a single 4.0Ah battery.”
SEESII Flagship 8-Inch Cordless Mini Chainsaw with Brushless Motor
The 8-inch bar gives this SEESII more reach than the six-inch Seesii Mini Chainsaw, while keeping the tool in the compact pruning-saw category. That makes it a useful middle ground for gardeners who often outgrow a smaller mini saw but don’t need the 16-inch cordless model. The listing specifies a 1000W brushless motor, automatic lubrication, and tool-free tensioning, plus two 4000mAh batteries and protective gear. The manufacturer claims more than 150 cuts per battery and an eight-second cut through a 15cm log; those figures are best treated as workload-dependent claims, not a guarantee for every wood type. Its eight-inch capacity still limits larger cuts, and no weight is provided, making it harder to judge comfort for extended use.
Pros:- Eight-inch bar offers more reach than the six-inch Seesii Mini Chainsaw
- Includes two 4000mAh batteries and a charger
- Brushless motor, automatic lubrication, and tool-free tensioning are specified
- Protective gear is included in the kit
Cons:- Eight-inch cutting capacity is limited for large logs
- Product data does not provide the saw’s weight
- Claimed cut count depends on the wood and cutting conditions
Best for: Gardeners and homeowners who regularly prune thicker branches and want more reach than a six-inch mini saw provides.
Not ideal for: People processing large logs or buyers who need published weight information before choosing a saw for sustained use.
- Chain length:8 inches
- Motor power:1000W brushless
- Battery:2 x 4000mAh
- Cutting speed:10 m/s
- Claimed cutting capacity:8 inches
- Claimed cutting time:15cm log in 8 seconds
- Oiling:Automatic lubrication
- Included items:Chainsaw, two batteries, protective gear, charger
Our verdict“Choose this SEESII for heavier pruning than a six-inch mini saw can comfortably handle, but move to a full-size model for large logs.”
How We Picked
I ranked these cordless chainsaws by how clearly their listed setup fits a real buyer’s work: pruning, occasional firewood cutting, or more demanding yard cleanup. Bar length and voltage helped distinguish likely use cases, while motor type, battery capacity, included batteries and charger, and features such as auto-oiling informed how ready each saw appears for sustained work. I gave more weight to a complete, well-matched kit than to a large power claim on its own, since the battery, bar, and intended workload need to work together.
The order also reflects tradeoffs a buyer can verify from the provided product details. Full-size models with batteries and chargers rise when they offer a practical balance of reach and kit completeness; compact saws rank highly for pruning-specific use but not as substitutes for larger saws. Tool-only or battery-platform-dependent models rank lower for shoppers starting from scratch, though they may be a better fit for owners of the matching platform. I did not treat wattage claims alone as proof of cutting performance, and buyers should check the exact battery compatibility, chain and bar specifications, and safety instructions before purchase.
Factors to Consider When Choosing Chainsaw Cordless
Choosing a cordless chainsaw starts with the work, not the biggest number on the package. The details that most often change the buying decision are the size of wood you cut, how long you work between charges, what batteries you already own, and how confidently you can control the saw.
Match Bar Length to the Wood You Actually Cut
A longer bar can reach across wider material, but it also adds reach and handling demands that may be unnecessary for routine pruning. For small branches and close-in trimming, a 6- or 8-inch mini saw can be easier to position than a 16- or 18-inch model. A 10- to 12-inch bar occupies a useful middle ground for light yard work, while larger bars suit buyers who regularly cut thicker wood and can handle the added tool size. Do not assume a bar’s full length equals the diameter you can comfortably cut in one pass; technique and the wood’s condition matter. Choose around the largest work you expect to do often, rather than buying extra length for a rare job. For trees or limbs under tension, hire a qualified professional instead of treating a larger saw as a substitute for experience.
Treat Battery Capacity and Runtime as Separate Questions
Voltage gives a broad sense of a platform, while amp-hours describe battery capacity; neither alone predicts how long a saw will cut in every situation. Dense or wet wood, repeated full-throttle cuts, chain sharpness, and bar size all affect battery drain. A kit with two batteries can reduce interruptions, but only if the batteries are compatible with the saw and the charger can keep pace with your work. Buyers who already own a tool platform should compare the cost and convenience of using their existing batteries with the value of a complete kit. A common mistake is buying a tool-only model and discovering that the needed battery or charger is a separate purchase. For longer sessions, check the manufacturer’s stated battery requirements and confirm what the package actually includes.
Choose a Platform Before Buying a Bare Tool
Battery ecosystems can shape long-term convenience as much as the saw itself. The BLACK+DECKER listed here is tool-only, while some DeWalt-compatible listings are designed around that battery format; verify exact compatibility rather than relying on a shared brand name or voltage label. A compatible battery may let you share packs across tools, but heavy chainsaw use can drain a small pack quickly and may call for a higher-capacity battery approved by the manufacturer. If this is your first cordless outdoor tool, a kit that includes both battery and charger is easier to evaluate as a complete purchase. If you already own batteries, compare the savings in reduced duplication against the runtime you may lose with the packs on hand. Check the saw’s manual for approved batteries before using third-party or cross-platform adapters.
Weigh Handling and Safety Against Cutting Reach
Compact saws can be easier to maneuver in pruning work, but small size does not make a chainsaw harmless or appropriate for one-handed use. Larger saws can reach thicker wood yet require more control, stable footing, and room to work. Before choosing, check the listed weight with battery installed, the handle layout, chain brake and other safety features, and whether the manufacturer specifies two-handed operation. Features such as a safety lock can help prevent accidental activation, but they do not replace protective equipment or safe cutting practices. Avoid buying a saw for overhead cutting simply because it is light; overhead chainsaw work carries serious injury risk. If the job requires climbing, awkward positioning, or cutting branches under tension, use a trained arborist.
Check Chain Care and Oiling Requirements
A cordless saw still needs routine chain care, and maintenance affects both cut quality and battery use. Automatic oiling can reduce the need to apply bar oil manually during work, but the reservoir still needs checking and refilling. A listing that mentions auto-oiling does not tell you how easy the system is to inspect or maintain, so look for clear instructions and available replacement chains. Keep the chain sharp and correctly tensioned; a dull or loose chain can cut poorly and place extra demand on the tool. Confirm whether the saw uses a standard replacement chain size or a less common configuration before buying. Budget time for maintenance even if your expected workload is only occasional trimming.
Pay for Capability You Will Use
A higher-voltage platform, brushless motor, longer bar, or extra battery can be worthwhile when regular cutting makes the added capability useful. Those features do not automatically make a model the right fit for light pruning, where a smaller, easier-to-position saw may be more convenient. Likewise, a compact mini saw should not be expected to handle the workload of a full-size model just because a listing uses a high wattage figure. Compare the whole kit: saw, batteries, charger, bar and chain details, and the manufacturer’s support information. If your needs are occasional and modest, favor a complete, easy-to-manage setup over headline specs. If you routinely cut larger wood, prioritize a platform and battery capacity suited to sustained work rather than choosing by bar length alone.
Frequently Asked Questions
Can a mini cordless chainsaw replace a 16-inch model?
Usually not: the mini saws in this lineup are aimed at pruning and smaller cutting tasks, while 16-inch models are intended for wider material and more substantial yard work. A compact bar can be easier to position on small branches, but it will be less suited to repeated cuts through thick logs. Buying a mini saw for large firewood work can lead to slow, awkward cutting and extra strain on the tool. If your jobs range from pruning to larger wood, choose based on the larger task only if you can safely handle the bigger saw. For occasional larger cuts beyond your skill or equipment, a professional service is the safer choice.
Should I buy a cordless chainsaw with batteries included or a tool-only model?
A kit with batteries and a charger is usually the simpler choice when you do not already own a compatible platform. It lets you judge the saw as a complete setup and avoids discovering that essential parts are sold separately. A tool-only model can be sensible if you already have the exact manufacturer-approved batteries and charger, but check capacity and compatibility before ordering. Chainsaw use can draw power quickly, so a small battery you use in another tool may not provide the runtime you expect. Compare the full package contents, not just the saw listing.
Is a 40V cordless chainsaw automatically more powerful than a 20V model?
Voltage alone does not settle which saw will cut better or work longer. Bar length, motor design, battery capacity, chain condition, and the type of wood all affect the result. This roundup includes different saw sizes and kit configurations, so comparing voltage without those details can give a misleading impression. Check the manufacturer’s cutting guidance and approved battery options for the specific model. Match the saw to your routine work rather than treating voltage as a direct measure of performance.
How do I choose between a 12-inch and a 16- or 18-inch cordless chainsaw?
A 12-inch saw is generally a more manageable fit for lighter yard work and moderate branches; 16- and 18-inch models offer more reach for larger cuts but are bulkier to control. Think about the diameter and type of wood you cut regularly, not the biggest piece you might encounter once. The larger options also make battery capacity, balance, and user experience more important during a session. If you are new to chainsaws, a longer bar is not automatically a safer or easier choice. Pick the shortest bar that suits your regular work, and leave difficult or hazardous tree jobs to trained help.
Are DeWalt-compatible cordless chainsaws a good choice if I own DeWalt batteries?
They may be convenient, but the phrase “DeWalt-compatible” is not enough to confirm that a particular battery will fit and operate as intended. Check the exact model’s battery specifications, approved pack requirements, and whether the listing includes a battery or only the saw. The 10-inch DeWalt-compatible product listed here includes a 4.0Ah battery and charger, while another listed model is described around a DeWalt 20V Max battery. Even with a compatible pack, runtime depends on battery capacity and workload. Use only batteries approved for the saw and avoid assuming that every pack in a platform will provide the same working time.
Conclusion
For most buyers seeking one capable saw with a battery and charger included, I would start with the EGO POWER+ 16-inch as the best overall pick. The Greenworks 40V 12-inch is my best-value-style choice for lighter yard work when a complete, more compact kit matters more than a long bar; check its battery capacity against your expected runtime. Beginners focused on pruning should look at a 6- or 8-inch mini chainsaw, such as the SEESII compact options, while learning safe handling and recognizing their limits. For a more demanding setup, the SEESII 40V 18-inch with two 5.0Ah batteries is the best premium-style fit in this lineup for buyers who want a longer bar and spare battery, provided they can manage the saw safely. If you already own a compatible DeWalt or BLACK+DECKER battery platform, compare those models’ exact battery requirements before choosing a tool-only or platform-based option. My final rule is simple: buy for the wood you cut most often, and do not choose extra bar length or power at the expense of control.
