I bought two of these units about one year ago. One is still functioning. The other failed after 3 months. .500 is a good batting average if you are a baseball player but not so for consumer products. I will not buy another nor recommend the product.

My daughter has one of these because her husband felt it was a good thing for her to have, when her battery died and she was stuck 2 hours waiting for a tow truck. She has used it numerous times for things like pumping up a trailer tire, jump starting their riding lawnmower with it, charging up her cell phone in a power outage, and tonight we just used it again during a five hour power outage as our main source of light. It has a 12 volt cigarette lighter style socket, a USB and wall outlet power source. We can't find anything bad to say about this little unit and I am going to buy one of these for myself when I return home. We Love this unit!!!!

Overall I like it, documentation is sparse, LCD readout is very nice, my main complaint it it does not come with a 12V adaptor so it can be charged form a car 12V outlet.

This thing cranked a car with a dead battery once for me. After that it just did not have enough power for the job. I used it to pump up a few tires (that were soft, not flat) and now it barely does that.

Now after using it 5 or 6 times, I have it on the charger and it won't go past 11.3 volts.

This unit was a replacement for another Stanley jump box that also failed after a month. Don't waste your money on this it will let you down.

BTW, the jump box I owned previously jumped dozens of cars and lasted for several years! It was a generic unit I bought on sale for $20! I am wishing I had not left it in the back of some car I worked on.

Bought it in Feb 2011. It would jump a lawn mower & small car, but not a pickup truck. Used for a while airing tires but by July 2012 the battery went completely dead & the power adapter (that charges the unit) went bad. Replaced the adapter & it still won't charge.

I have a 'Power on Board' 450 amp Jump-Start, that was purchased in 2005 for $45 that is still working good. I wish I could find another like it (even at twice the original price).

Don't waste your money on this Stanley product.
