 Buying guide

Is this going to be your first purchase and you are not sure what to look out for before purchasing a 40V chainsaw, go through our extensive buying guide. You will find useful tips. 


When purchasing a 40V cordless chainsaw, the first consideration should be its safety features. Safety features like a low kickback mechanism or emergency chain brake, scabbard or bar sheath, and handguard are vital for a 40V cordless chainsaw.

Hence, when we were selecting the chainsaws listed in this review, we ensured that these safety features are incorporated. Other safety gear is also vital for the user to get before using the chainsaw. Some of them are safety boots, pants, safety glasses, earmuffs, and head protection.


Most brands produce other power tools such as mowers, weedeaters, and many others, and most times, they have compatible batteries or chargers; this becomes an added advantage for such buyers.

Brushed or brushless motor:

The advantage of a brushless motor in the 40V chainsaw is enormous. It ranges from increased efficiency, power/torque, numbers of cut per charge, lifespan, and reduced friction. The 40V WEN, 40V Ryobi, and 40V 16 inch GreenWorks chainsaws fall in this category.


In purchasing a 40V chainsaw, the cost is also a prime factor to consider. Including a charger and a battery,  innovation such as a brushless motor, and the chainsaw blade length, affects the cost. The GreenWorks 12 inch chainsaw that comes without a charger and battery is the cheapest on our list at $80. The cheapest chainsaw with the brushless motor innovation is the Ryobi 40V chainsaw. 

Other costs like that of spare battery, charger, and oil should be considered, amidst maintenance costs.  

Bar Length:

The bar length of the 40V cordless chainsaw also determines the wood thickness the chainsaw can conveniently cut. The highest bar length in this review is 16 inch which will conveniently cut a 14-inch thickness.

Comfort and Weight:

While purchasing a 40V chainsaw, check out for the weight and the features that promote comfort. For instance, the Greenworks 12 inch chainsaw listed above weigh less than 8 pounds. Apart from the portability, all the chainsaws except the Ryobi 40V chainsaw have the automatic oiler for ease in chain tensioning adjustment without the tools. The wrap-around features are also a common feature possessed by most chainsaws in this review for efficient cutting in several angles. Overall, these features should ensure minimal fatigue after extended use. 

Do you still have questions, check through the frequently asked question below.


  1. Are battery-operated chainsaws worth the money?

However, when looking at the overall size and balance, cutting speed, overall ergonomics, and lesser price, Greenworks appears superior. Therefore, depending on the features you desire most in a chainsaw, you can determine the better one for you.  

  • What better gas or battery chainsaw?

Answer: Generally, the better chainsaw depends on the factor under consideration. Most professional chainsaw users compare the chainsaw in terms of power, and definitely, the gas chainsaw cuts trees with much power compared to the battery-powered ones. Nevertheless, with much innovation by battery-powered manufacturing companies in producing brushless motor engine chainsaws, there is much efficiency, more torque/power, almost like the gas chainsaws.

While in terms of noise, weight, and maintenance, the battery chainsaw is better. Thus, for professional and heavy-duty tasks, gas chainsaws are a better option. While, battery-powered ones are suitable for yard cleaning and other small duty. 

From this review, we believe you have made the right pick from our Best 40V chainsaw. With the right 40V chainsaw in your arsenal, you can be sure of making cuts with high efficiency and speed and less fatigue after extended use. Have a happy sawing with utmost comfort and less noise.
