Quick verdict
An 18 inch chainsaw from the Greenworks 82V commercial line with a 2.7 kW brushless direct drive motor, an 82 ft/s chain speed, a mechanical chain brake, steel bucking spikes and a 4.0 Ah battery and charger in the box. It suits anyone felling small trees, bucking real firewood or clearing storm damage who wants gas-class pace from a battery. The caveat is the platform: 82V packs do not fit Greenworks 80V tools or the reverse.

Who this chainsaw is for
Greenworks sells its 82V line to landscapers and to homeowners who want landscaper gear, and the 82V 18 inch chainsaw kit is the clearest case for it. It pairs a 2.7 kW brushless direct drive motor with an 18 inch bar, a mechanical chain brake, steel bucking spikes and a wrap-around handle, and it ships with a 4.0 Ah battery and charger. Greenworks rates it as the equivalent of a 55 cc gas saw. It is aimed at felling small trees, bucking firewood and clearing storm damage, work that most 40V saws finish slowly.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The kit contains the saw with an 18 inch bar and chain, one 82V 4.0 Ah battery and a charger. The motor is a 2.7 kW brushless direct drive unit, and Greenworks quotes a chain speed of 82 feet per second with a maximum of 13,000 rpm held under load. The saw has an automatic oiler with a flip-up cap and a transparent oil tank, heat treated steel bucking spikes, a mechanical chain brake and a wrap-around front handle. Greenworks rates it for up to 210 cuts through a 4×4 on one charge and says it runs three times quieter than gas with low vibration. The packs are not compatible with Greenworks 80V tools; the two lines are separate. Weight, chain pitch and gauge and charge time are not stated in the listing.
Cutting and power
A chain speed of 82 feet per second is gas-saw territory and higher than most consumer battery saws publish. Combined with 2.7 kW, it means the saw pulls through rounds up to the bar length without the pause-and-push rhythm of a smaller battery tool. The bucking spikes let you pivot the saw into a large log the way a gas saw does, and the wrap-around handle gives a proper grip for felling cuts and for working on the side of a log. Owners of Greenworks 82V saws describe cutting pace close to a mid-size gas saw in seasoned hardwood and a motor that holds rpm instead of sagging, which is exactly what the direct drive design is for.
Runtime and batteries
An 82V 4.0 Ah pack holds about 330 watt-hours, and Greenworks rates it for 210 cuts on a 4×4. In firewood terms that is a good session of bucking, not a full day, and a second pack is the first thing a heavy user should budget for. The 82V packs run the rest of the Greenworks 82V commercial range, including blowers, trimmers and mowers, but nothing from the 80V consumer range, which has caught out buyers who assumed the two were interchangeable. Charge time is not stated.
Build, handling and ergonomics
The transparent oil tank with a flip-up cap means you can see the level and refill without a cap wrench. The mechanical chain brake is the standard hand-guard design and Greenworks lists it plainly. The saw is described as lightweight and low vibration; it will still be heavier than a 16 inch homeowner saw once the 4.0 Ah pack is fitted, and the long bar rewards a two-handed, braced stance. The tensioning method is not described in the listing.
Living with it
Keep the oil tank full, since a saw this fast chews a dry bar quickly, and use real bar and chain oil. Sharpen often; a sharp chain on a high speed saw is the difference between clean chips and dust. Confirm chain pitch, gauge and drive link count from the bar before ordering spares. Greenworks publishes a warranty for the 82V tools and batteries on the product page; the commercial line typically carries different terms from the consumer line, so read them.
Alternatives to Consider
The EGO Power+ CS1810 18 inch saw is the main rival on a far larger battery platform, sold tool-only. The Greenworks 80V 18 inch chainsaw kit costs less and shares packs with the consumer 80V range, with a lower power rating. For a buyer who wants a gas-class saw and does not mind gas, the Echo CS-590 Timber Wolf 20 inch is the benchmark at this bar length.
Verdict
Buy the Greenworks 82V 18 inch kit if you fell small trees, buck real firewood or clear storm damage and want gas-class chain speed with a battery and charger in the box, and you are either starting fresh or already on 82V. Skip it if you own Greenworks 80V packs, since they will not fit, or if your cutting is light enough that a 40V 16 inch saw would cover it for less.

Greenworks 82V 18-Inch Cordless Chainsaw with 4.0 Ah Battery and Charger FAQs
No. Greenworks states plainly that this saw is not compatible with its 80V products. The 82V line is the commercial range and uses its own packs and chargers.
Greenworks rates it for up to 210 cuts through a 4x4 on a single charge. Firewood rounds in hardwood use far more energy per cut, so plan on a good session of bucking rather than a full day, and consider a second pack.
Greenworks lists tree felling among its uses, and the 18 inch bar, steel bucking spikes and wrap-around handle are the right equipment for small to medium trees. Large timber remains the job of a professional gas saw and a trained operator.
No decibel figure is given. Greenworks says it runs three times quieter than gas, and battery saws of this size are far less noisy than a two-stroke, but a fast chain in hardwood still calls for ear protection.
