Stanley j5C09-500-A jump starter/compressor reviews

I've got a similar one ( Black and Decker brand ) that I got at Lowe's or H Depot. Works....pretty slow to put air in tires with it, but it's will do it if you have time. And yes, I have used the jump start part of it....sometimes it works, sometimes not. If the battery is really low on the vehicle you are trying to jump, this thing just can't do it. Overall, I feel it's worth carrying, so it stays in the storage of the trailer while traveling.
