GreenWorks 20312 Cordless Chainsaw Review Review


Upon first glance, this looks like a little green monster, and seems to dare you to try it out. As a cordless, battery-powered chainsaw, the GreenWorks 20312 Cordless Chainsaw speaks softly, but carries (saws) a big stick, delivering smooth, clean cuts, a long chain life, and a new attitude about battery-powered, cordless saws.

Let’s talk a little bit more about this lean, green machine and what it offers in terms of power, performance, and durability. We just might convince you open your horizons and try this out—because as they say, once you go cordless, you don’t go back.


Let’s be honest: Having a cordless tool like the GreenWorks 20312 Cordless Chainsaw makes life much more convenient for the higher, up-in-the-tree jobs. There’s no dealing with a cord in the way, there’s no worries about how far it will go. And at less than 7 pounds, it’s like lifting up your Yorkie. But without all the yipping. But that’s just the beginning of all of the features this chainsaw has to offer.

GreenWorks 20312 Cordless Chainsaw takes ion-lithium technology to the next level with 30% more torque and up to 70% less vibration than gas powered chainsaws, and applies an innovative brushless motor technology that allows for a longer life, better efficiency and less noise, that makes this saw a perfect tool for users of any sawing experience – novice or veteran.

This chainsaw packs a heavy-duty Oregon bar and chain, chain brake, metal bucking spikes, and an automatic oiling system that gives this saw a commanding, durable presence, whether doing small yard work chores or helping in natural disasters. This saw does the job quickly and efficiently.

Other Features

There’s an automatic oiler that is facilitated by first unscrewing the tethered cap at the left side of the saw and filling it with chain oil. You can control the chain tension and chain removal by two dials on the right side of the saw that are easy to use. The chain is very impressive as it seems to retain tension very well. Much like traditional chainsaws, the GreenWorks 20312 saw has a lot of safety features, including a chain brake and a low kickback chain, a hand guard and a trigger that shuts off the saw when not in use.

The power button is a momentary switch, so activating or deactivating the saw is controlled by the internal electronics, which also facilitates the automatic time-out after after a minute or so of inactivity to prevent the battery from discharging. Restarting the saw is a breeze with a push of the button, especially if you are perched at 20 feet in the air. No more pull-starting.

And the performance? Once you get over the typical short learning curve of battery-powered chainsaws, getting to the actual sawing becomes a lot of fun. The quietness of the saw is almost surreal – other than the normal motor whine and cutting through material, the noise is impressively low – which is a great option if you live in a neighbourhood with close neighbours.

The steel Oregon blade and chain on this saw are .043 gauge, designed to provide more cutting power with less motor strain. For a battery-powered saw, this is a great option. This also allows for less hassle in cutting more larger-diameter wood with fewer bog-down.

Good for the Environment

Choosing a battery-powered saw is also an eco-friendly choice. Unlike gas-powered chainsaws, there are no more of those nasty emissions and no messy oil and gas mixing. A battery-powered saw has minimal operating costs. As time and technology improves in the arena of chainsaws, we are seeing more and more eco-conscious consumers toss their gas guzzling saws and switch to electric or battery-powered chainsaws because they are cleaner, more environmentally-friendly, and they are less expensive to operate. Having a cordless chainsaw eliminates the afterthought of dancing around a cord while working.

Why We Liked It

This little green mean machine was easy to power on and able to push through our many different cutting jobs with no issues. The light weight and portability of this chainsaw made it very convenient to do the high-up, hard-to-reach work. Being a quieter model is a nice option, especially with the neighbors. And the brushless technology that means a longer, healthier motor life. And having many safety features gave us peace of mind in doing our work with full confidence. Well done, Greenworks!


For ease of use, GreenWorks 20312 Cordless Chainsaw is portable, mess-free, and performs great for felling trees or lighter trim work, and is one of the quietest saws we have reviewed. The removable battery and lightweight base makes this saw easy to handle and operate for anyone, regardless of experience.
