Got a S-10, haven’t started it in about four or five months, battery totally dead, saw the jump starter kit, thought I would give it a chance, thinking for sure it probably won’t work or at least it would require multiple attempts; read the instructions, connect the cables correctly, turned the key……started right up, no problem! Great for someone who travels a lot, someone who has an older vehicle (& battery), great for college students. Can’t go wrong with the Portable Power Bank; if you don’t like it, you can always return it!

Great product! Great to have when you need it.

Seems ok so far, I have not tried to start a vehicle with it yet, but it did charge my phone

Item looks great! Have not been able to use it yet but expect it to be awesome!

so far it works but I think only on vehicles that ran today and the batteries are dead and won't start down the road. I tried it on a vehicle that was down almost a month but it took 3 tries to get it started and it drained the jump pack's battery. I recharged it and it works still.

The item is just as advertised, of that I am happy. Would definitely recommend.

Looks good, haven't used it yet.

Directions are printed so small I can hardly read them. If not for already having one of these it would be really hard to read instructions.

its a great product, i gave it 4 stars because the only thing it needs to make it perfect is a nice little zip up carrying case instead of the box
