StarkPower 12V, iSparQ 600A Lithium-ion Jump Starter with USB, LED, Charger

I have a 100 ah 12 volt battery made by StarkPower and I love it, So I decided to give this a try. Within a week of getting it we had some -20 weather and my GF's Honda civic died. I hooked this baby up and It started right away without hesitation. VERY IMPRESSED! as for the other features, the flashlight is blindingly bright and the charge ports all work great. I have not charged a laptop yet, but I'm sure it will do fine. This baby is going everywhere with me. Thanks again StarkPower, I love your stuff!

I bought this several months ago, but have had little opportunity to use it, so I waited to write a review until I knew what it could do. I've used it to charge a phone and a tablet and everything worked as promised. The reason I got it was to use it as a jump-starter for our cars. This morning, my wife BMW X3 experienced battery failure -- it wouldn't even "click". It was very easy to hook up and it started the 3.0 liter 6-cylinder engine immediately and with no hesitation. Based on our experience this morning, I would be very comfortable recommending this to anyone else.

This little box is pretty amazing ! It does all kinds of things from jumping a dead battery to charging up your mobile devices. This is one of the best investments I've ever made.

I mainly bought this as a travel charger for USB devices, but it has also jumped a beefy 4-cylinder pickup truck. Started right up!!

This is great. I've used it to charge electronics so far. Haven't used it yet to jump start my car, but I store it in the trunk for the day that I need it!

Could not start a dead battery as advertised. The red cable hot hot after few try outs. Went back to conventional old fashioned charger and got it to start.Lousy!

When we ordered this product, the one we received initially did not work and evidently we had an incorrect phone number for requesting a replacement. Eventually all was rectified and we received a completely new unit. It has worked beautifully! We needed this for multiple vehicles from 4 wheeler to boat to airplane. Jon with StarkPower has gone out of his way to make sure we were happy with the starter/charger. We are very pleased with it at this point. The new unit does everything promised and so we have no problem recommending this to others, as it had been recommended to us. It's small size and light weight belies just what an amazingly powerful little workhorse it is. Great for so many applications.

booster exploded while jumping an audi caught customer car on fire, $3345 in damages!!! will not buy again
