Best Greenworks 40V 12 in Cordless Electric
As an Amazon Associate we earn from qualifying purchases.
A search for best greenworks 40v 12 in cordless electric points to one product: a 12-inch Greenworks chainsaw that runs on a 40V lithium-ion battery. The listing under this ASIN is the version sold with a 2.0 Ah battery and charger, and the title names tree felling, firewood cutting, storm cleanup, limbing and pruning as its uses. The listing gives one runtime figure, 50 cuts on a single charge in 4×4 treated wood, and it gives two different weights. This post covers what the listing states, what it leaves out, and when this saw is the wrong buy.
Quick answer
- The listing describes a 12-inch chain on a 40V battery platform. The version with a 2.0 Ah battery and charger is the one named in the title.
- The only runtime figure is 50 cuts on a single charge in 4×4 treated wood. The listing gives no minutes and no motor type.
- The weight is listed as 10.9 pounds in the spec table and as 6 lbs in a bullet. Plan for the heavier figure until the manufacturer clarifies.
- Skip it if you need a stated motor type, a runtime in minutes, or a maximum cutting diameter. The listing gives none of them.

Who it suits
This saw fits a yard owner who clears limbs, trims small branches and deals with storm debris a few times a year. The listing names those jobs in its title and bullets, and it describes the saw as suited to yard work, emergencies and camping. The listing presents the size, the battery and the light weight as the main reasons to buy, so those are the points to check against your own jobs.
Before you buy, answer three questions. First, what is the diameter of the wood you cut most often, compared with the 12-inch bar? Second, do you already own a Greenworks 40V battery, or will you need to add one? Third, can you carry 10.9 pounds, or 6 pounds as one bullet suggests, for the length of your typical job? If the answers point to larger wood or longer sessions, the listing does not give enough figures to settle the question, and a saw with stated specifications may suit you better.
The listing says the 40V battery works with other Greenworks 40V tools. If you already own a Greenworks 40V mower, trimmer or blower, the shared battery is the strongest reason to look at this kit. The listing does not say whether a second battery of a different size fits the saw, so check that before you buy extra packs. If you are weighing the platform for other tools, our Greenworks 40V electric lawn mower guide covers the same battery line in a different tool, and our Greenworks vs EGO Power+ string trimmer comparison looks at Greenworks string trimmers against a rival line.
Before the first cut
The listing does not replace chainsaw safety guidance, and the extension pages used in this post make the same points about any saw. Penn State Extension states that “Kickback is a leading cause of chainsaw-related injuries.” It also says that “The chainsaw should be equipped with safety features such as a chain brake, throttle lock, and anti-vibration systems.”
Oklahoma State University Extension gives two short rules that apply to this saw. The first is “Make sure the chain brake is on.” The second is “Keep both hands on the saw.” The same article says “Kickback occurs when the rotating chain hits a solid object or the chain is pinched in a cut,” which is the reason the grip matters.
The listing does not mention a chain brake. The Agricultural Safety and Health page describes “Chain brakes, a feature of gas chainsaws, reduce the risk of injury, if activated, by stopping the saw’s chain immediately if kickback occurs.” That line is about gas saws, so it does not tell you whether this battery saw has a brake. Ask the seller or read the manufacturer’s manual before you assume it does.
Cornell Small Farms adds a caution about low-kickback chains. It says that kickback-reducing devices are things to select for, and that “These devices will reduce but will not prevent kickback.” The listing does not describe this saw’s chain as low-kickback, so this post does not make that claim. Cornell also advises: “Watch the guide bar nose. Do not let it touch logs, branches, or the ground when the saw is running.”
For face protection, the Agricultural Safety and Health page says to “Wear either a full-face shield or safety goggles or safety glasses with side shields to protect your face from flying wood chips, twigs, and sawdust.” Penn State Extension also warns that “Avoid cutting above shoulder height: Overhead cutting increases the risk of kickback and recoil.”
Chain condition matters as well. Penn State Extension states that “Sharpness of the chain: A dull chain requires more force to cut and is more likely to cause kickbacks.” The listing’s tool-free tensioning makes adjustment quick, but the listing does not describe a tension check, so use the manufacturer’s manual for that step rather than relying on the bullet alone.
Skip it if
- You need a runtime in minutes or a stated motor type. The listing gives only the 50-cut figure and does not name the motor.
- You plan to cut logs close to the full 12-inch bar length in one pass. The listing gives no maximum cutting diameter, so you would be working from guesswork.
- You want the saw to run on batteries from another brand. The listing says only that the 40V platform works with Greenworks 40V tools.
- You already own a 40V battery and want the tool alone. The listing shows a tool-only option, so choose that version rather than the battery-and-charger version.
What the listing does not say
Battery and charger. The title says the saw comes with a 2.0 Ah battery and charger. The listing also shows a tool-only option, and the saved text does not spell out every difference between the two versions. Check the version before you buy.
Runtime. The only runtime figure is up to 50 cuts on a single charge in 4×4 treated wood. The listing gives no minutes, no charge time and no cut counts in other wood, and it does not say what it counts as one cut.
Weight. The listing gives two figures and does not reconcile them. The spec table says 10.9 pounds. A bullet says “Only 6 lbs (2.7kg) with wrapped grip: easy to carry for outdoor/camping use, no fatigue during long sessions.” The two figures disagree, and this post shows both rather than picking one.
Motor and speed. The listing does not state whether the motor is brushed or brushless, and it gives no chain speed.
Oil and tension. The listing names an auto-oiler and tool-free tensioning. It gives no oil capacity and no instructions for checking chain tension.
Warranty. The listing says the tool and battery carry a 3-year warranty. It does not say what the warranty covers or how to make a claim.
Horsepower. The spec table prints 0.73. The listing does not explain how that figure was produced, so this post does not compare it with any other saw.
How we chose
This post covers one product. Its ASIN is B09Y6D7CTY, and the listing is titled Greenworks 40V 12 in Cordless Electric Chainsaw, 2.0 Ah Battery and Charger. The keyword and the ASIN were assigned together in this batch. The listing was read on 2026-10-23, and only its title, bullets and specification lines were saved. Shopper feedback on the page was not recorded and is not used anywhere in this post.
The post does not rank this saw against other chainsaws, and it does not call it the best or the most powerful 12-inch saw. It is in the post because it matches the keyword and because the listing gives enough stated specifications to describe the product accurately, with the gaps shown.
The safety section draws only on university extension and Cornell Small Farms pages that were opened on 2026-10-22 and checked against their text. Where the listing is silent on a safety feature, the post says so rather than filling the gap.
What we could not verify
The sources we opened do not cover this model’s specifications. The listing is the only source with figures for this saw. The listing also links a user manual as a PDF, and the sources used here are HTML pages, so the manual’s contents are not covered.
As a result, this post cannot confirm the motor type, the chain speed, the oil capacity, the charge time, the maximum cutting diameter or the battery weight. It also cannot confirm the 50-cut figure, which is the listing’s own claim.
The extension pages describe chainsaws in general. None of them describes this model, so the safety section is general guidance and not a statement about this saw’s features.
FAQ
Is the Greenworks 40V 12 inch chainsaw good for firewood?
The title names firewood cutting, but the listing gives no maximum log size and no firewood cut count. Compare the 12-inch bar length with the log diameters you plan to cut, and keep the bar nose away from the ground and other wood while the saw runs, as Cornell Small Farms advises.
Does the kit include a battery and charger?
Yes, for the version named in the title, which is the 2.0 Ah battery and charger. The listing also shows a tool-only option, so confirm which version you are buying.
How many cuts does one charge give?
The listing says up to 50 cuts on a single charge in 4×4 treated wood. That is the only runtime figure in the saved text. This post has not verified it, and the listing does not explain what counts as one cut.
Does the battery work with other Greenworks tools?
The listing says the 40V platform works with Greenworks 40V tools. It does not say the battery works with tools from other brands, so do not assume it does.
How much does the saw weigh?
The listing gives 10.9 pounds in the spec table and “Only 6 lbs (2.7kg)” in a bullet. Plan for the heavier figure if you carry the saw up a ladder or for long periods, until the manufacturer clarifies which is right.
Does this saw have a chain brake?
The listing does not mention one. Penn State Extension says a chainsaw should be equipped with safety features such as a chain brake. The Agricultural Safety and Health page describes chain brakes as a feature of gas chainsaws, so read the manufacturer’s manual or ask the seller to confirm before you buy.
Bottom line
Buy this kit only if you can carry the heavier 10.9-pound figure and you already run Greenworks 40V batteries or plan to start with them. If you need a stated motor type, a runtime in minutes or a maximum cutting diameter, look for a listing that states them and check the manufacturer’s manual before you buy.
