It offers strong cutting power with 3.4 kW and can make up to 205 cuts per charge.

Our Testing Experience
First Impressions
When I first took the Greenworks 82V 20″ Brushless Cordless Chainsaw out of the box, I was impressed by how solid and well-built it felt. The size was just right—not too heavy, but sturdy enough to handle tough jobs. I charged the 4.0Ah battery fully and was eager to see if it would really live up to the promise of making over 200 cuts on a single charge. Setting it up was easy, and I liked the clear oil tank that made it simple to check the oil level before starting.
Daily Use
Using the chainsaw every day around the yard and on some small tree projects was surprisingly smooth. The automatic oiler kept the chain well-lubricated without me having to constantly stop and check. I noticed the wrap-around handle gave me great control, especially when making tricky cuts. The mechanical chain brake felt safe and responsive, which gave me confidence during use. The motor was quiet compared to gas chainsaws I’ve used before, but it still packed a powerful punch when cutting through thick branches and 4×4 lumber.
Key Features in Action
The brushless 3.4 kW motor really stood out during my testing. It handled heavy cutting without bogging down, which is impressive for a cordless tool. The heat-treated steel bucking spikes helped anchor the saw firmly while cutting, making the process easier and safer. I also appreciated the flip-up oiler feature with the transparent tank; it made refilling quick and hassle-free. Plus, the dual port rapid charger meant I could charge two batteries quickly, so I never had to stop working for long.
Long-Term Performance
After several weeks of regular use, the Greenworks chainsaw showed no signs of slowing down. The battery life remained strong, and the saw kept cutting smoothly without any issues. The build quality held up well, with no loose parts or wear on the handle or chain brake. Overall, it proved to be a reliable and efficient tool that could easily compete with gas-powered chainsaws. For anyone who needs a cordless option that doesn’t sacrifice power or convenience, this saw is a great choice.
