High-quality cordless chainsaw that's great for small/medium gardens.
- BestReviews
The thing that makes this unit great is its reliability and longevity. On top of that, you can take it wherever you want without having to think about extension cords and gas refills. In other words, when it comes to convenience – this is the ideal solution. On the other hand, it does have certain limitations due to the lack of power. The other thing we liked is the price. While many cordless models tend to have a pretty hefty one, this model is surprisingly reasonably priced. Now, that doesn’t mean it’s a cheap piece of equipment per se, but it’s definitely a worthy investment for people that are going to use its full potential. Also, the 2-hour recharge time doesn’t seem as long as one would expect.

The most notable feature of the Black and Decker 40V chainsaw is its side-loading 40V battery which powers the saw without the need for 2-cycle fuel. You still need to add chain oil to keep the Oregon 12″ bar and chain lubricated, but the battery and electric motor are what’s driving the saw as it cuts.

The fact that this is for light work means that it should stand up to regular use. All components have been fitted well, and the construction of the large tension adjuster is also noteworthy, allowing for tool free adjustment.
- Power Tools Ninja
The BLACK+DECKER 40V MAX lithium ion chainsaw comes with a long-lasting lithium ion battery that has a long run time and a longer life than many comparable batteries. It also has a tool-free chain tensioner adjustment option for easy maintenance.
- The Consumer Guide
The Black+Decker LCS1240 can do more work with less effort than small chainsaws, with it's 12" bar and 40V motor.
- Outdoor Ideas
The convenience of portable, cordless maneuverability gives these Black & Decker cordless Chainsaws a well-deserved place in our top ten. This battery-powered, cordless saw sports a tool-free chain tension system to provide powerful sawing with fast, efficient cuts, an ergonomic-friendly full wraparound handle, and weighs only 8 pounds, so it is easy and convenient to port anywhere.

This is a powerful chainsaw that is popular for its ability to the convenience of cordless maneuverability. It provides the needed power to cut through live wood and logs. It has a 12-inch bar and chain. This includes a tool free chain tension that provides serious cutting power and fast and efficient cuts. The need for manual oiling of this saw is eliminated with this tool. The tool emits the oil by itself. It constantly oils the bar and chain as needed.

You can control battery life thanks to a charge indicator. Black & Decker electric chainsaw is very compact and lightweight. The battery can be used in other Black & Decker tools.

Comfortable full wrap-around handle. Low-kickback for fast and smooth cuts.
- Wood Working Toolkit
Oregon low kickback bar and chain minimizes vibration and improves cut speed. Window provides easy visibility for gauging oil level and 40-volt lithium-ion battery can hold a charge for up to 18 months.
- Yard Care Life
The Black and Decker LCS1240 is the cheapest model we reviewed while still a great quality small saw.
- The Pro Cutter
This chainsaw possesses a saw arm of 12 inches, allowing it to cut stumps and branches of up to 12 inches in diameter. Equipped with an automatic oiling system, it stays lubricated as long as it’s filled with oil. Like the other B+D chainsaw reviewed on our list, this chainsaw can have its tension adjusted without the use of a tool.
- ConsumerExpert.org
Small handy elegant design. Less chain tension with auto lubrication system.
- Tech Rater

It is so lightweight and ergonomic that you can cut in many angles. In addition, there is a low kickback bar to reduce the risk of getting injured for the chainsaw user. Lastly, it also has auto-tensioning and auto-oiling features.

What experts didn't like
Small bar size, modest performance, moderate battery life.
- BestReviews
As with all other cordless models, most people will struggle with the certain limitations such as power or battery capacity. The other thing that is being frowned upon by many users is the lack of oil capacity. In other words, make sure you keep the bar and chain oil handy because of the small reservoir capacity. It’s not a major downside, but it’s definitely one worth pointing out. The battery sometimes needs time to cool off before starting the recharge cycle. It will error out most of the time while it’s hot.

The bucking spikes are plastic, so there’s not a ton of leverage you can get with the saw if you happen to be cutting into larger diameter logs.

One downside to this particular battery and charger set, is that the recharge time is between 4 – 4.5 hours for a full charge from empty. This time is significantly longer than some competing battery powered chainsaws.
- Power Tools Ninja
Might leak oil hence advisable to empty the oil tank after use.

Oiling system feeds too much oil on a bar, so you might need to fill it quite often.

Significantly pricier. Relatively smaller chain bar.
- Wood Working Toolkit
Battery only lasts about 30 minutes with continuous use and chain speed is lower than a gas chainsaw.
- Yard Care Life
Extra sharp some time prove dangerous.
