. It's an 80-volt mower, and it works exceptionally well. I chose it because it was on sale at Lowes, but if I were buying right now, I'd opt for this model from Greenworks. It's basically the same as the mower I own — except for the color, and I actually like green better anyway — so I'm confident that it will perform just as well.
The 80-volt platform offers more than enough power for my lawn, which is a pretty typical size for a suburban lot, and even the 2Ah batteries will last for about three full mows. Amazon is offering, one with two 2Ah batteries and one with a single 4Ah battery. Those add up to the same capacity, so you can just pick whichever is cheaper. Batteries can be purchased separately, too, and will work in any of that brand's 80-volt tools.
The power is perfectly sufficient for cutting all manner of standard Midwestern weeds, and upon recently picking up a competing brand's string trimmer owned by my father, I was surprised to discover that this Black+Decker version was astonishingly lightweight in comparison, making it easy to use it one-handed to get to the lowest weeds in my front-yard drainage ditch.
I'm perfectly happy with this as my sole weed whipping solution, however, I will say that its edging capability should probably only be expected to be used for maintenance-type situations. If you're really looking to edge into some overgrown lawn, you'll probably need something more heavy-duty. —I picked up an older equivalent of this mower a few years ago after moving into a house with a relatively small lawn .
It's much quieter than any gas mower I've ever used, to the point where I don't even bother with ear protection; it's like pushing a medium-sized box fan around the yard. This is a nice bonus for me since one of my neighbors works nights and I don't have to worry about waking him if I decide to mow in the middle of the day. It's lightweight and easily folds down to about the size of the deck when not in use, plus it requires virtually zero maintenance.
