Black And Decker 40v Chainsaw Review – Worth Buying or Not?

Black and Decker 40V – A truly amazing electric cordless chainsaw; perfect for your backyard and lawn duties!

This chainsaw comes with a 12-inch-long bar and chain, which obviously isn’t a big chainsaw but is perfect for what it’s designed for. You can cut and trim branches very easily and conveniently, in no time, and you can even cut wood logs that are up to 6 inches thick. It is affordable, has a good built quality, and is simple to use – and most homeowners find it sufficient for all their yard-cutting needs.

A small chainsaw does not have the capacity to cut massive pieces of wood, so don’t expect it to. Due to its battery-powered nature, you won’t be able to get a huge amount of power out of this machine – understandably. Even so, it is great for cleaning up, trimming, and pruning.

We’ve been using this saw for a couple of years now, and based on our personal experiences, our article contains a detailed review of it, along with what we liked and what we didn’t like about it.

Black and Decker 40V Chainsaw: What separates it from Its Competitors in 2023?

First of all, it’s an excellent homeowner saw! Not big, but still worth using. I’d say being a cordless electric chainsaw is one of its biggest advantages because people, especially beginners cannot directly go to the gasoline saws. This is because gasoline saws are usually bigger, and require more concentration and attention to use so, newbies often find it a struggle to deal with them.

Moreover, this chainsaw is perfect for women, who are into managing their lawns and backyards by themselves. It is compact, light in weight has a good battery timing that gets charged up in 120 minutes, the ergonomics are perfect, and it’s affordable too.

Reviewing Black and Decker 40V LCS1240 – How Well Does It Perform?

How long does a 40V 4.0 Ah battery last?
A 4.0 Ah battery with 40 volts of power will last for about fifty minutes on a single charge. More powerful machines will have less battery runtime because the bigger the machine, the greater the power it consumes in less time.

4.0 Ah of obviously. The runtime of a 4.0Ah battery is exactly double that of a 2.0Ah battery so it’s better.

Yes, you can. These batteries are designed in a way that they stop consuming power once they’re fully charged which means they do not get overcharged. And so, they don’t get harmed.
