Every tree owner knows the frustration: a gas saw that refuses to start after sitting for three months, or the cloud of two-stroke exhaust that follows you around the yard. Electric chainsaws have matured past those compromises, offering instant start power that rivals gas displacement numbers you recognize. The deciding factor today is no longer battery versus gas — it’s which electric platform delivers consistent torque through a full bar of wood without triggering thermal shutdown.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. I track brushless motor efficiency curves, battery cell cooling architectures, and chain pitch compatibility across the category to separate genuine gas equivalents from underpowered pruners.
When you need a saw that starts every single time and cuts through hardwood without the ritual of mixing fuel, the right electric chainsaw for cutting trees becomes your most reliable outdoor tool, not another maintenance burden.
How To Choose The Best Electric Chainsaw For Cutting Trees
Buying an electric chainsaw requires matching three variables to your typical tree size: available battery platform power, bar length versus log diameter, and whether the motor can sustain full torque through continuous cuts without overheating. Skip one variable and you end up with a saw that stalls halfway through a trunk or runs out of charge before you finish limbing.
Bar Length and Chain Pitch
The bar determines the maximum log diameter you can cut in a single pass — a 16-inch bar handles logs up to roughly 14 inches, while an 18-inch bar can manage 16-inch trunks. Chain pitch (measured in inches between drive links) affects cutting speed and smoothness: 1/4-inch pitch delivers fine, precise cuts ideal for limbing, while 3/8-inch low-profile pitch clears chips faster on larger wood. A mismatched pitch for your bar length creates unnecessary friction and slower cutting.
Battery Voltage and Amp-Hour Capacity
Higher voltage platforms — 60V versus 40V — generally translate to higher sustained torque because the motor draws more power before hitting current limits. But voltage alone doesn’t tell you runtime: amp-hours (Ah) multiplied by voltage gives watt-hours, the real energy reservoir. A 40V 4.0Ah pack holds 160 watt-hours, while a 60V 2.0Ah pack holds only 120 watt-hours despite the higher voltage. For serious cutting on trees over 10 inches, target at least 180 watt-hours per battery cycle.
Brushless Motor and Active Cooling
Brushless motors eliminate carbon brushes for higher efficiency and longer life, but the real differentiator is whether the motor has active cooling — a fan that pulls air over the windings. When you bury the bar in a hardwood trunk for 30 seconds of continuous load, an uncooled motor can pull current and reduce power to protect itself. Saw platforms with active cooling maintain full torque longer and recover faster between cuts.
Automatic Oiler Output and Tank Size
Chain lubrication determines both cut quality and bar wear. An automatic oiler that delivers consistent flow at high and low RPM keeps the chain riding smoothly on the bar. Oiler output measured in milliliters per minute varies dramatically across models — saws with larger oil tanks (over 6 ounces) let you cut through multiple trees before refilling, while small tanks force you to stop mid-job. If you cut dry, seasoned hardwood, oil consumption rises, so a larger tank is a practical advantage.

In‑Depth Reviews
1. Husqvarna Power Axe 225i
Husqvarna’s 225i brings the brand’s pro heritage into a cordless package that weighs only 6.8 pounds with its 4.0Ah battery installed. The pass-through battery design keeps the saw balanced in your hands, reducing fatigue during extended overhead limbing. A boost mode activates 25% more power on demand, which helps when you hit a knot or slightly oversized branch that would stall a standard 40V saw.
The active cooling system is the hidden engineering advantage here — it pulls air across the battery and motor to maintain consistent power output even after several minutes of continuous use. Real users report cutting 6 to 8-inch dead elm for nearly two hours on a single charge, which suggests the cooling allows the battery to deliver closer to its full rated watt-hours without thermal throttling. The tool-free chain tensioning is smooth and holds adjustment through vibration better than some plastic-dial systems.
For a 14-inch bar saw, the 225i punches well above its displacement class. The limitation is bar length — you won’t cut through 14-inch logs in a single pass, and the small oil tank requires filling roughly every one to two battery cycles. Buy this if you value lightweight handling and want a saw that starts instantly and runs quietly enough to use in noise-sensitive areas.
What works
- Active cooling prevents thermal throttle
- Boost mode adds real torque for tough knots
- Pass-through battery balances perfectly
What doesn’t
- Small oil tank needs frequent refills
- 14″ bar limits single-pass log size
2. DEWALT DCCS672X1
The DCCS672X1 represents DEWALT’s second-generation 60V FLEXVOLT chainsaw, and the improvements over the first generation are immediately apparent. The brushless motor delivers 26% more peak power than a 40.9cc gas chainsaw, with torque figures that approach 2.5 times the gas equivalent. This isn’t marketing math — real users report cutting through 12 to 20-inch maple trees for six hours, swapping batteries between cuts.
The 18-inch bar gives you the reach to fell trees up to 16 inches in diameter without flipping the saw, and the auto-oiling system provides continuous lubrication with a quarter-turn oil cap for fast refills. Chain adjustment uses an onboard wrench stored in the rear handle, which is less convenient than tool-free systems but more secure under heavy vibration. The inertia-activated chain brake is responsive and adds safety during kickback events.
Where this saw loses some ground is battery life under sustained load — the included 3.0Ah FLEXVOLT pack gives you roughly 1.5 to 2 hours of moderate cutting, but heavy bucking on hardwoods drains it closer to 45 minutes. Owners already invested in the 60V FLEXVOLT platform will find this the obvious choice. For new buyers, the price of additional 9.0Ah batteries adds up fast.
What works
- True gas-level torque on hardwood
- 18″ bar handles large diameter trees
- Onboard wrench for secure chain adjustment
What doesn’t
- Included 3.0Ah battery drains fast on heavy cuts
- Rear handle design is heavier than top-handle options
3. Milwaukee 2727-21HD
Milwaukee’s 2727-21HD is the most powerful electric chainsaw on this list when measured by raw motor output — 5.3 horsepower from the M18 FUEL brushless powerhead. That figure translates into real-world capability: real users cut through 18-inch diameter seasoned ash logs on a single 12.0Ah battery charge, and the saw handled Russian olive root systems without stalling. The 16-inch bar is conservative for the motor output, which means the saw never labors even when buried in a thick trunk.
This tool is designed for the M18 platform’s high-output batteries. The 12.0Ah HD battery provides 2 to 3 hours of mixed cutting, while smaller 5.0Ah packs tend to overheat and shut down under continuous load — that’s an important buying consideration if you already own Milwaukee tools with smaller batteries. The overload protection circuit kicks in to prevent motor damage when you push too hard, but it recovers quickly once you ease off the trigger. The dual bar bolts and metal clamp system provide better bar retention than single-bolt designs.
The main downsides are weight and balance. At nearly 21 pounds with a 12.0Ah battery, this saw is heavier than most cordless competition, and the battery placement behind the rear handle creates a nose-heavy feel during horizontal cuts. The trigger area has an awkward cutout that some users find uncomfortable with gloved hands. The oiler also has a known tendency to leak when stored with the bar pointed down, a common complaint across multiple owner reports.
What works
- Highest motor horsepower on the list
- Handles 18″+ hardwoods without stalling
- Overload protection prevents motor damage
What doesn’t
- Heavy at 21 lbs with big battery
- Requires high-output 12.0Ah battery for full runtime
4. Worx WG385
Worx markets the WG385 Nitro as “better than 45cc gas,” and while that’s a bold claim for a 40V saw, the chain speed of 59 feet per second combined with the brushless motor’s torque curve makes it feel close in practice. Users repeatedly describe the cutting action as “butter” — the slim 3/8-inch low-profile chain clears chips efficiently without bogging down on 10-inch hardwood logs. The 16-inch bar is ideal for the power output, allowing single-pass cuts on logs up to 14 inches.
The battery engineering here is worth noting: Worx claims up to 150 cuts on 4×4 hardwood per charge with the included 4.0Ah pack. Real-world owners report cutting through 25 pieces of mixed wood and still having one bar of battery left, which places the effective runtime around 45 minutes to an hour of continuous cutting. The tool-free chain tensioning dial is one of the best implementations on the mid-range market — it uses a metal gear rather than plastic, so it holds tight under vibration without loosening mid-cut.
The kickback brake is triggered by inertia and stops the chain within milliseconds. The battery charge indicator on the tool body is a practical touch — you can see remaining power at a glance without pulling the pack. The main criticism is the bar oil cap, which can leak when stored upright; owners recommend storing the saw on its side. The charger is also slower than premium platforms, taking over two hours to fully recharge the 4.0Ah pack.
What works
- Fast 59 ft/s chain speed for clean cuts
- Metal gear tensioning holds adjustment
- Battery indicator on tool body
What doesn’t
- Bar oil cap leaks when stored upright
- Charger is slower than 60V platforms
5. DEWALT DCCS670T1
The DCCS670T1 is the first-generation 60V FLEXVOLT offering from DEWALT, and it remains a compelling option because of its 3-horsepower brushless motor that punches well above the 16-inch bar’s expected performance. Real-world users report cutting through 16 to 18-inch hardwood without slowing the chain, and one owner documented dropping a 30-inch tree using both sides of the bar — a testament to the motor’s ability to handle oversized cuts when you work around the bar length limitation.
The tool-free chain tensioning and bar tightening knob use a single interface, which simplifies chain adjustments in the field. The auto-oiling system delivers consistent flow at all RPMs through a quarter-turn oil cap that makes refilling quick. The chain brake is responsive and includes a hand guard that activates on kickback. The included 2.0Ah battery provides decent runtime for light trimming, but owners doing serious cutting almost universally recommend upgrading to a 9.0Ah FLEXVOLT pack for real productivity.
Weight is a strong point — at under 1.5 pounds for the tool alone (battery not installed), this is one of the lightest 60V saws available. The compact design makes it easy to maneuver in tight spaces. The primary drawback is oil leakage: many owners report bar oil seeping out during storage, a common trait among chainsaws but more pronounced on this model than some competitors. The included 2.0Ah battery is also undersized for the motor’s appetite, so factor in battery upgrade costs when budgeting.
What works
- Extremely lightweight for a 60V saw
- Tool-free tensioning and bar knob are intuitive
- Handles 18″ hardwood without bogging
What doesn’t
- Bar oil leaks during storage
- Included 2.0Ah battery drains very fast
6. Greenworks GCS80420
Greenworks positions the GCS80420 as a professional-grade saw with its 80-volt platform — the highest nominal voltage of any cordless chainsaw on this list. The 2.7-horsepower brushless motor produces torque comparable to a 42cc gas chainsaw, and the 18-inch bar gives you the reach to fell trees up to 16 inches without repositioning. Greenworks claims up to 150 cuts on 4×4 lumber per charge, though real-world experience with an 80V 4.0Ah battery shows more like 60 to 80 cuts on hardwood before the pack needs swapping.
The automatic oiler runs consistently at all chain speeds, and the easy-adjust tensioning system uses a side-access dial that doesn’t require removing the bar nut — a faster design than traditional side-tension systems. The push-button start with no choke or primer makes operation straightforward, and the noise level is noticeably lower than gas saws in the same class. Owners upgrading from the 60V Greenworks platform will appreciate the interchangeability of batteries across the 80V lineup.
The most common real-world complaint is an internal breaker that trips when you force the saw through a cut too aggressively — the motor beeps and stops for about 15 seconds before resuming. This is a thermal or current protection feature that gas saws don’t have, and it requires adjusting your cutting technique to let the saw do the work. The saw is also fairly heavy at 10.8 pounds without battery, and the charger for the 80V platform is not particularly fast — expect 90 minutes to fully recharge a depleted 4.0Ah pack.
What works
- Highest voltage platform (80V) for sustained torque
- 18″ bar handles large diameter trees
- Comparable power to 42cc gas saw
What doesn’t
- Internal breaker stalls when forced too hard
- Battery cannot be pushed — must let saw work
7. Caterpillar DG631
Caterpillar’s DG631 brings a 60-volt brushless motor and 18-inch bar to a price point that undercuts most premium 60V competitors. The “Brushless Motor 2.0” design claims 40% more power than standard brushless motors, and the chain speed of 78.7 feet per second is genuinely fast — it cuts through softwood like pine almost effortlessly. The included 5.0Ah battery and charger make this a true kit that doesn’t require extra investment to start cutting immediately.
The tool-free chain tensioning uses a dial system that maintains adjustment even after extended use, a design improvement over some cheaper tensioners that loosen under vibration. The inertia chain brake is responsive and engages quickly on kickback. The slim chain profile reduces friction compared to wider 18-inch chains, which helps the 60V motor maintain speed through longer cuts. The saw weighs 13.1 pounds with the battery installed, which is competitive for an 18-inch bar saw.
The weak point is the supplied bar and chain — multiple owners report that upgrading to an Oregon 16-inch bar and chain dramatically improves cutting smoothness and reduces kickback. The battery charging time of 90 to 120 minutes is also long compared to fast-charging platforms like DEWALT or Milwaukee. There are scattered reports of battery failure after 10 to 20 charge cycles, though this appears to affect early production units more than recent stock. Check the manufacture date before purchasing.
What works
- Fast 78.7 ft/s chain speed for clean cuts
- Full kit includes 5.0Ah battery and charger
- Tool-free tensioning holds adjustment well
What doesn’t
- Stock bar and chain need upgrading for best performance
- Slow 90-120 minute charge time
8. Makita XCU11Z
The Makita XCU11Z is a tool-only offering designed for owners already invested in the 18V LXT platform. The 14-inch bar and 1,520 feet-per-minute chain speed are modest on paper, but the Makita-built brushless motor delivers impressive torque for its voltage class — users report cutting through 6-inch hardwood limbs and 6×6 lumber without struggling. The rear handle design makes it maneuverable for pruning and small tree work.
Real-world runtime depends heavily on battery capacity. With a 5.0Ah LXT battery, owners report 30 to 45 minutes of moderate cutting, which is sufficient for clearing storm damage or processing a few small trees. The saw is noticeably quieter than gas alternatives, and the absence of fumes makes it usable in enclosed spaces. The chain tensioning uses a side-access screw that requires a tool, which is less convenient than tool-free dials but more secure under load.
The XCU11Z is not designed for felling large trees — the 14-inch bar limits single-pass cuts to around 12 inches, and the 18V platform runs out of steam on logs over 10 inches in diameter. The rubber grip and ergonomic handle design are comfortable for extended use, but the saw needs a larger 5.0Ah or 6.0Ah battery to be productive. If you already own Makita 18V tools, this is a cost-effective way to add a capable pruning saw to your lineup.
What works
- Excellent torque for an 18V platform
- Quiet, fume-free operation
- Compact and maneuverable for tight spaces
What doesn’t
- 14″ bar limits single-pass log size
- Tool-based chain tensioning less convenient
9. SKIL PWR CORE 40 TH1200C-11
SKIL’s PWR CORE 40 is the most budget-friendly entry on this list, but it’s not a compromise for the right use case. The 12-inch bar and 40-volt brushless motor deliver the equivalent of a 27cc gas saw, which is plenty for limbing branches up to 5 inches and cutting trunks up to 8 or 10 inches. The 1/4-inch pitch chain provides smooth, precise cuts that leave cleaner surfaces than coarser chains — ideal for pruning where tear-out matters.
The battery technology here is surprisingly advanced for the price point. SKIL wraps each individual lithium cell with a cooling material that keeps temperatures down during discharge, resulting in 25% longer runtime and double the battery life cycle compared to uncooled packs. The IPX4 weather resistance rating means the saw can handle rain and wet conditions without electrical failure — a meaningful feature for outdoor work. The auto-lubricating chain extends bar life, and the tool-free chain tensioning dial is accessible even with work gloves.
Real-world users consistently report that the 2.0Ah battery lasts about an hour of intermittent use, and the quick 15-minute charge time means you can work continuously by rotating two batteries. This saw is not for felling large trees — owners who push it beyond 10-inch logs find the motor bogging down. But for a homeowner who needs to clean up storm damage, prune overgrown limbs, and cut firewood from small diameter trees, the TH1200C-11 delivers surprising value in a lightweight, fatigue-reducing package.
What works
- IPX4 weather resistance for wet conditions
- Quick 15-minute charge time
- Lightweight and easy to maneuver
What doesn’t
- 12″ bar limits to branches and small logs
- Battery life is short for continuous use
Hardware & Specs Guide
Battery Voltage and Watt-Hours
Voltage determines how much power the motor can draw before hitting current limits. Higher voltage platforms (60V, 80V) deliver more sustained torque under load compared to 40V or 18V systems. But watt-hours — voltage multiplied by amp-hours — is the true measure of energy stored. A 40V 4.0Ah battery (160 Wh) will run longer than a 60V 2.0Ah battery (120 Wh) despite the lower voltage. For cutting trees over 10 inches in diameter, target at least 180 watt-hours per battery cycle to avoid mid-job swaps.
Chain Pitch and Gauge
Chain pitch is the distance between drive links, measured in inches. Standard pitches for electric chainsaws are 1/4-inch (smooth, fine cuts for limbing), 3/8-inch low-profile (most common, good balance of speed and control), and 0.325-inch (aggressive, for larger logs). Gauge refers to the thickness of the drive links fitting into the bar groove — 0.043-inch and 0.050-inch are standard. Using the wrong gauge causes the chain to sit too loose or too tight in the bar, leading to poor cutting and accelerated wear.
Brushless Motor Torque Curve
Brushless motors eliminate carbon brushes for higher efficiency, but not all brushless motors are equal. The torque curve — how much twisting force the motor delivers at different RPMs — determines whether the saw maintains cutting speed when you bury the bar in hardwood. Motors with peak torque at lower RPMs are better for bucking large logs, while motors that deliver torque across a wide RPM range are better for mixed cutting tasks. Active cooling (a fan over the motor windings) prevents thermal throttling during sustained cuts.
Automatic Oiler Flow Rate
Chain lubrication is non-negotiable for bar and chain life. Automatic oilers should deliver between 5 and 12 milliliters per minute depending on bar length and cutting conditions. Saws with adjustable oilers let you increase flow for dry hardwood and reduce flow for softwood or light pruning. Oil tank capacity matters — a 6-ounce tank lasts roughly two to three battery cycles, while smaller 3-ounce tanks require refilling mid-job. Always use bar and chain oil (not motor oil) to maintain proper viscosity and adhesion to the chain.
