[This review was collected as part of a promotion.] I bought this to replace a 12V powered pump I keep in my trunk. Not having to turn on car power or start car to keep battery from being drained is a life changer. I topped off 2 vehicles, 2 bicycles, and a motorcycle in about 10 minutes. Love the auto stop and presta valve holder. Used a 4AH battery and was still basically full when done.
[This review was collected as part of a promotion.] I purchased the battery inflator to replace an older model from another brand. This tool works so much better than the old one.It is literally faster and lighter, even with the battery installed!
[This review was collected as part of a promotion.] First off, I’d buy this again. However, it’s not perfect. Pro: Small & light. Runs off 12V and 40V batteries. Auto shutoff when pressure is reached. Has both high and low pressure inflate, and low pressure deflate. Has a built-in light. Comes with a Presta valve adaptor. Con: Kinda noisy. Does not keep the last pressure setting when turned off, so pressure has to be reset every time you use it. Instructions are not very good so you have to spend some time fiddling with it to figure out how it works. 12V cord and high-pressure hose storage is not easy to use. This is a good unit, but there are enough minor Cons to knock off one star.
It is an ok compressor/inflator, but do not rely on its pressure readout. It is wildly inaccurate. I had to "over inflate" by up to four pounds to get to the real, desired pressure. As I already have a few Greenworks products and the requisite batteries, I will keep it. If you are not already committed to Greenworks, you might want to look elsewhere.
No, I would not recommend this to a friend.
