I haven't used it yet. It arrived and when i unpacked it I found that it is supposed to be charged for 40 hours. CORD NOT INCLUDED.

Works great! Has saved me numerous times when my car battery died on Christmas. It has filled many tires for me as well.

Easy to use, convenient size. Have used 4 times to start my car with no problems. Very easy to pump up tires, also.

Great all around piece of auto equipment. Jump-start the car, inflate tires, even charge your cell phone. Great price, too.

if you have never used one of these it is so much better than jumper cables even if helping someone else

Brought it home and plugged it in. Wasn’t long before I needed to use it to jumpstart my lawnmower. Works like a champ!

This Stanley Fatmax Jump Box is awesome! It has very bright safety lights, can inflate tires, USB charge 4 devices,, and jump your car fast!

Great product. Has already proved useful when a family member had a dead battery. Very convenient to inflate tires. Extremely easy to use

Its a nice to have but it needs replaced in a few years. This is my second one. Once you have it, you can not live without it.

I would have gave it 5 stars but it does not come with a cord to plug it in the wall to charge so I had to get a extension cord to do it.
