The Husqvarna Power Axe 350i is the most capable 40V saw in this lineup, with an 18-inch bar that lets you buck 16-inch hardwood rounds in a single pass — something no other saw in this class can claim. Its brushless motor, combined with a Boost Mode that adds 25 percent extra power on demand, actually delivers cutting speed comparable to a 50cc gas saw. The included 7.5Ah battery is the largest capacity pack among all nine models, giving you sustained runtime for serious firewood processing sessions that last several hours before needing a swap.

The X-Cut chain maintains its sharpness noticeably longer than standard Oregon or proprietary chains, reducing the frequency of filing stops. The tool-less tensioning system works well when the chain is warm, though a few users report that the plastic tension assembly can deform if the chain pinches during a cut. The charger, unfortunately, takes 6-7 hours for a full recharge, so you’ll want a second battery pack if you plan to work through an entire weekend day. The saw weighs just 7.7 pounds with the battery installed — lighter than most 16-inch gas saws — and the pass-through battery design keeps the center of mass over your forward hand, reducing arm fatigue.

This is a legitimate gas-replacement saw for property owners who cut firewood or clear trails multiple times per year. It’s not overkill for a suburban yard, but the 18-inch bar, massive battery, and price tag reflect a tool built for sustained output rather than occasional limb trimming. If your workload includes 8-inch-plus trees and full truckloads of firewood, this is the 40V saw that keeps pace without you ever touching a pull cord.

The Power Axe 225i brings the same engineering DNA as the 350i but in a lighter, more maneuverable package that excels at limbing and pruning work. The active cooling system keeps the battery temperature regulated during sustained cuts, preventing the thermal shutdown that plagues lesser saws when you push them through a dense hardwood.

Boost Mode is included here too, and it makes a tangible difference when cutting 6- to 8-inch dead elm or oak rounds. Real-world reports consistently show the 4.0Ah battery delivering roughly two hours of intermittent cutting before needing a recharge, which is enough to fill the back of a Toyota 4Runner with firewood. The tool-free chain tensioning is quick and requires no fiddling, though a few users mention the chain can loosen slightly during the first few cuts of a session and needs a quick re-tension after the initial break-in period.

The 225i is the best choice for anyone who needs a reliable, everyday battery saw for storm cleanup, pruning, and property maintenance without the bulk and cost of the 350i. It’s quiet enough to use in suburban neighborhoods without disturbing neighbors, and the lack of exhaust fumes makes it comfortable to work with for extended periods. If you already own other Husqvarna battery tools, the interchangeable battery system adds real value by consolidating your power platform.

SKIL’s PWR CORE 40 chainsaw stands out because of its Auto PWR JUMP charging technology, which pushes the 2.5Ah battery from zero to 30 percent in just 15 minutes. In practice, this means you can work through a battery in 30-45 minutes of intermittent cutting, plug it in during a quick break, and be back to full power faster than any other saw on this list. The digital brushless motor is efficient and delivers smooth cutting through 8- to 10-inch wood without bogging, though it lacks the raw torque of the Husqvarna or DongCheng units when pushing through dense hardwood.

The saw itself weighs 11.5 pounds with the battery installed, which is on the heavier side for a 14-inch saw. The tool-free chain tensioning dial is easy to use even with work gloves on, and the automatic oiler keeps the chain well-lubricated without needing constant adjustment. The anti-kickback brake is responsive and cuts power almost instantly, which adds confidence for newer users. SKIL backs the tool with a 5-year limited warranty, one of the longest in this category.

The upside is that the same battery works across SKIL’s entire PWR CORE 40 platform, including their pole saw and string trimmer, so the investment scales if you’re building a cordless yard-tool ecosystem. For light to moderate weekend use where short charging breaks are acceptable, this saw delivers excellent value.

The Greenworks 40V 14-inch chainsaw has been a consistent top seller for years because it nails the basics at a competitive price point. Its TruBrushless motor delivers 2x more torque than brushed alternatives, and the company rates it for up to 75 cuts through 4×4 lumber on a single 2.5Ah charge — a claim that aligns with real-world reports of 45-60 minutes of mixed cutting. The saw is lightweight at 7.6 pounds, making it one of the easiest full-size 14-inch saws to maneuver for overhead pruning and ladder work.

The automatic oiler is reliable and keeps the chain lubricated through extended cuts, though the translucent oil window is small and can be hard to read in low light. The tool-free chain tensioning uses a simple knob system that works well but requires periodic checks — some users report the bar nut can loosen over time if not tightened firmly.

This saw is ideal for homeowners who need a reliable, low-maintenance tool for seasonal pruning, storm cleanup, and cutting smaller firewood. It starts instantly, runs quietly, and produces zero exhaust, so you can use it in tight spaces without worrying about ventilation. The Greenworks 40V battery platform includes a wide range of outdoor tools, so if you already own a Greenworks mower or trimmer, this chainsaw is a natural and cost-effective addition to your arsenal.

The Worx WG384 distinguishes itself from every other saw in this guide with its automated chain tensioning system — you don’t turn a dial or loosen a nut; the saw adjusts chain tension itself during operation. This is a genuine convenience for users who don’t want to fiddle with adjustments mid-job, though some users note that the auto-tension system doesn’t hold the chain as tightly as a manual adjustment, and the chain can occasionally pop off when cutting dense, knotty wood. The saw uses two 20V 2.0Ah Power Share batteries in series to deliver 40V of power, and those batteries are compatible with Worx’s entire 20V and 40V tool ecosystem.

The dynamic brushless motor provides consistent torque, and the chain speed is listed at 26 ft/s — adequate for cutting limbs and logs up to 10 inches thick. The Quick Stop chain brake is responsive and must be disengaged before pulling the trigger, adding a layer of safety that’s especially welcome for newer operators. The saw weighs 10.4 pounds and has a well-balanced design, though the battery level indicator on the tool is a nice touch that lets you gauge remaining runtime at a glance.

Battery life is the main limitation: the two included 2.0Ah batteries provide about 45 minutes of intermittent cutting before both need recharging. The included dual charger can top them up simultaneously, but the total runtime per cycle is shorter than what you get with a single 4.0Ah pack from Greenworks or Wild Badger Power. If you’re already invested in the Worx Power Share platform — or if automatic chain tension is a priority for you — the WG384 is a solid mid-range performer. For heavy cutting, you’ll want to supplement with larger-capacity Worx batteries.

The RYOBI 40V HP Brushless chainsaw is a tool-only purchase, which means you need to bring your own 40V RYOBI battery and charger to the equation. For users already invested in RYOBI’s 40V platform — which includes mowers, trimmers, blowers, and hedge trimmers — this is the most cost-effective upgrade path available. The saw itself weighs just 6 pounds, making it the lightest saw in this entire guide, and the HP brushless motor delivers impressive torque for a tool this small. Real-world users consistently report that it performs on par with small gas saws for tree felling and limbing up to 10-inch diameter.

The tool-free chain tensioning is straightforward, and the automatic oiler keeps the bar lubricated effectively. The saw feels well-balanced despite its light weight, and the safety features — including a lock-off switch and a responsive chain brake — inspire confidence even for users transitioning from gas saws. The 14-inch bar handles most residential cutting tasks, and the brushless motor’s efficiency means you get good runtime even with a mid-capacity 4.0Ah battery, yielding about 45-60 minutes of active cutting per charge.

The biggest catch is the absence of a battery and charger in the box, so if you’re starting fresh, the initial investment will be higher once you factor in buying a compatible pack. The 30-day limited warranty is also notably shorter than what SKIL and Greenworks offer, which is a consideration if you want long-term peace of mind. But for RYOBI loyalists, this is an excellent, lightweight, and surprisingly powerful chainsaw that integrates seamlessly into an existing battery ecosystem.

The DongCheng 40V 16-inch chainsaw comes with two 4.0Ah batteries in the box — a total of 8.0Ah of runtime capacity, which is second only to the Husqvarna 350i in total energy. The kit also includes a fast charger that can replenish both packs in under 20 minutes each, meaning you can cycle through batteries continuously with minimal downtime. The high-torque brushless motor and 16-inch bar make this saw capable of handling 14-inch logs in a single pass, and the chain speed is rated at 14 m/s (about 46 ft/s), which is among the fastest in this group.

The tool-free chain tensioning uses a convenient external dial that allows for quick adjustments, and the automatic oiler keeps the chain well-lubricated during extended cutting sessions. The saw includes an anti-kickback chain brake that engages in under 0.1 seconds, and the lock-off switch prevents accidental startups. Build quality is solid for the price point, with a well-balanced design that weighs under 10 pounds with batteries installed. Some early units had issues with the chain oiler, but recent batches appear to have resolved that problem based on updated customer feedback.

This saw represents exceptional value for anyone who needs sustained runtime for medium-to-heavy cutting without paying Husqvarna or Greenworks prices. The dual-battery system is a genuine advantage for users who want to cut for extended periods — you can drain one pack while the other charges, keeping the saw running all afternoon. The DongCheng 20V/40V battery platform also works with the brand’s other outdoor tools, so if you’re willing to adopt a less mainstream ecosystem, the savings are substantial.

The Wild Badger Power 40V 16-inch chainsaw delivers a remarkable chain speed of 49 ft/s — the fastest in this entire guide — which means it slices through wood with minimal operator effort. The brushless motor produces 1.5 horsepower, and the 4.0Ah battery provides enough runtime for cutting 6-inch limbs and logs for about an hour of continuous use. At just 11 pounds, it’s well-balanced and easy to maneuver, and the ergonomic grips reduce fatigue during longer sessions.

The tool-free chain tensioning works smoothly, and the automatic oiler keeps the bar lubricated effectively, though some users note that the oil output is on the lighter side — you may need to check the window more frequently. The safety brake stops the chain instantaneously, and the lock-out switch prevents accidental startups. The saw is part of Wild Badger Power’s 40V platform, so batteries are interchangeable with the brand’s mowers, trimmers, and blowers, adding value if you expand your tool set later.

The biggest concern with Wild Badger Power is customer service consistency — a small number of users report difficulty getting support for missing items or defective units, though the saw itself generally receives strong reviews for performance and value. The 49 ft/s chain speed is a genuine standout feature that makes this saw punch well above its price bracket in cutting aggression. If you’re willing to accept the trade-off of a less established brand for class-leading chain speed, this is the saw to beat in the value tier.

The Litheli 40V 12-inch chainsaw is the smallest and lightest saw in this guide, designed specifically for pruning, limbing small branches, and cutting firewood up to 8 inches thick. Its compact form factor makes it ideal for users who prioritize maneuverability over raw cutting capacity — you can easily use it with one hand for overhead trimming or while standing on a ladder. The magneto motor delivers a chain speed of 26 ft/s, which is adequate for the bar length and keeps the cut moving without excessive vibration.

The 2.0Ah battery is rated for up to 36 cuts through 4×4 lumber per charge, which aligns with real-world reports of about 45 minutes of mixed trimming work. The tool-less chain tensioning uses two easy-to-turn knobs, and the 120ml automatic oiler includes a translucent window for checking oil levels at a glance. The saw stops within 0.1 seconds after releasing the trigger brake, and the bumper spike helps reduce fatigue during sustained cuts by transferring force to the wood.

Extra batteries for the Litheli platform can be hard to find, which limits your ability to hot-swap for longer jobs. The saw also struggles with dense hardwoods over 10 inches thick; its 550-watt motor simply lacks the torque for heavy bucking. But for its intended role — quick, quiet pruning and small-branch cleanup — the Litheli is a capable and affordable entry point into 40V cordless cutting.
