With frequent power outages due to storms, the ability to charge our phones and have a powerful light it is great! Add to that the air compressor and jump cables its a must in our home and vehicle

The unit holds a charge for a long time. We love the set it and forget it when it comes to airing up tires. I haven't needed to jump off our vehicle but it jumped off several vehicles on our trip. Great product!!!

Great product! I forgot to charge my speaker but this handy dandy tool has some USB ports so we were able to enjoy our music and air up our bikes too! My daughter has used it to jump her car before buying a battery. We love it!

air hose is poorly designed, very difficult to put back into unit cut my finger trying to shut door. don't think it would inflate 3 tires as claimed. jumper was weak and would barely turn over my lawn tractor.

Suppose to weigh 10 lbs. Actually wrighs 16.8 lbs. Too heavy for a disabled 77 yr. Old to pick up or move around. Otherwise has every function you would need. Very disappointed that i could not handle the size.

This is the second one I bought. The first one lasted3 years then just quit. I replaced it with this one and it has been about 6 weeks and the thing won't turn off!

I had purchased one a couple of years ago, it was an excellent booster and also the tire pump is excellent. I purchased this as a present for my grandson he would be very happy with this tool..

This works well and has plenty of USB ports, the only thing I wish it had was an actual electrical outlet/socket to directly plug in items like my old one did.

We had a power outage soon after my purchase, and was able to keep USB items charged. Haven't tried the car start option yet, but It revived my m/c battery, instead of having to purchase another. In that, this FatMax has already paid for itself!

Works great, all in one charger. Bought one for my husband 2 years ago, now have bought 3 more for each of my kids for gifts per their requests ( and per my husband's so they will quit borrowing his)
