Customer Ratings & Reviews

This can be used for car or truck. Small but very useful.

it's light and easy to carry. great function，easy to use.

Both your phone and a car jump starter! You can't beat it!

The device comes in handy. I carry it with me on road trips just in case. If the battery is completely dead in the vehicle, it will not boost it off. It does boost off if there is still about 7V left on the battery. I charge my phone with it more than anything.

Amazing little gadget. My father’s car wouldn’t start. His battery was completely dead after leaving the lights on all night. He tried charging the battery the old method ways. He wouldn’t believe me this device would do the job. All I did was plug it to the battery and turn the key. That car started right away.

Got this for a steal via a Deal of the Day. Fortunately I haven't had the need to use this yet but it does help that if I need to jump (or if I need a jump), the possibility of onboard computer functions will not be in danger of being shorted out due to a battery to battery power surge. This thing is a good idea.

Used it to help start my lawn tractor when the battery was a bit weak. Aside from charging my iPhone, this is a good emergency backup charger for your car. Haven’t used it to start a completely dead battery yet.

I bought this as a gift for my son. He has not told me whether he likes it or not.

This works really well. It does take a long time to get an initial charge but then charges many things. I took this on Ragbrai and it was amazing. I have also jumped 2 things with the jumper cables. This goes with me everywhere

Love this item! Charges your car and your phone. Doesn't work so well if your car battery is completely dead or needs to be replaced. But if your headlights and interior lights come on then you should be ok.

Was able to start my diesel truck with this. My batteries were not completely dead but the starter would not engage. One of my truck batteries had a bad cell.

This charger has been quite useful for charging the phones and iPads when a normal power source has not been available. Luckily, we haven't had to try to jump starting ability of it yet.

I purchased this to jump start my car, and it worked quicker than I expected. instructions are simple. I plan on keeping one of these in each of my vehicles for the winter.

Enough to start 5.3 and 3.6 liter, V8 and V6 Chevy engines in mild California winters. I plan to pack this charger on all future road trips.

I bought it to be prepared for any emergencies in the car. Luckily, I haven't used it for actual situation, but this product gives me a peace of mind for sure!!

I have many old cars so never know when I need one of these! It works great as well as charges my mobile devices since my cars don't have cigarette lighters!

Hopefully, I don't have to use it but I'm confident to have this device in the event my battery won't start.

I haven't put it to a major test yet but I think it will be great as a back-up for my Honda Silverwing.

You can’t beat this for a price but it takes longer to jump a car then and normal jumpstart box.

Cannot even get help if you have no way to charge a dead battery. Did not want my wife to rely on a stranger in an emergency!
