Black & Decker LCS120 Review


The 20-volt Max lithium-ion battery will provide a lifetime of use and will retain its charge 5 times longer than comparable 18-volt NiCad batteries without the bother of an extension cord. This Black and Decker cordless chainsaw is perfect for anyone that dislikes gasoline engine tools. Many reviewers are happy with the performance of this light weight and easy-to-use chainsaw when doing their yearly spring cleaning.


However, the instructions received with the saw could be written in simpler terms but other than it being a challenge to read and follow directions; once the saw is together it runs beautifully. Perfect cordless saw for light, small jobs but not exactly built for the more traditional jobs like tree cutting. An unfortunate negative factor about cordless power tools is that they don’t usually hold power long enough for the average trimming or lightweight job. Many reviewers recommend getting an extra battery to solve the problem.


Made with the budget-conscience buyer in mind, this cordless Black & Decker LCS120 is designed with the home lawn care person in mind who battles spring cleanups, and does small chores requiring the light weight power and convenience of a battery operated tool in order to accomplish the lighter lawn tasks such as tree trimming without having to spend the big bucks on a gas-powered saw.

Read What User Say

I was in the market for a cordless chain saw for some seasonal trimming and weather-related fallen limbs and decided to go with rechargeable vs. gas powered. I like the power that the LCS120 offers to do its thing. The battery it comes with lasted a while as nothing was overly think. Thankfully, I have the same battery for a cordless blower so was able to change to the second battery without stopping work. They recharge pretty quickly too when you run through a whole charge. Good time to take a break so you don’t get too tired using the thing. However, this thing is amazingly light so you won’t tire too easily. With the battery, you’re just over 5 pounds and it didn’t feel heavy at all after all the work I had to do. The thing I probably like best is you don’t have to worry about how many times you have to pull the cord to start the motor. You have push-button start with a safety to prevent accidentally starting her up. Thank you.

One can’t do a review of this product without mentioning their instructions for putting the whole thing together. Overall, it was easy for me, but I can see where others might have some troubles. This is one thing Black & Decker does well in most cases as they know their target audience. Just have patience. It almost felt like putting a bookshelf from Ikea together. Of course, this one had a chain to install, too, which was probably the most troublesome.

If you need to cut something more than 8-10 inches across, this will do the job, but a heavier duty piece of equipment is probably your better bet, unless you just have one tree to cut and already have this chainsaw. It is an 8” chain, but it struggled a bit with the larger pieces. This is more of a lightweight chainsaw, that functions perfectly well, but is not really meant for the bigger jobs.

You will need a supply of “good quality chainsaw oil” to install before running the thing. While you don’t need gas to power it, the chainsaw oil keeps the chainsaw well lubricated so it runs its best. Just don’t mix it up with the oil for the salad dressing. The track needs to be well oiled to run smoothly. You don’t want it to lock up in the middle of a major sawing operation.

If you already have a gas-powered chainsaw, you’ll quickly learn when to use one over the other. The lightweight B&D model has an upper limit on what it can realistically cut without having to swap the battery out after a couple of really deep cuts. And you don’t want to take out a really heavy gas-powered baby if you’re just cutting up some smaller pieces. At a minimum, you can hang the axe back up in the garage. As it will handle splitting firewood pretty easily for you. Just be sure all the fingers and toes are still there when you’re done.
