Customer Ratings & Reviews

Powerful, reliable, fits perfectly in the glovebox. Last season it fired up 3 cars and still had enough to charge my cellphone. If you’re looking for a jump pack don’t hesitate, buy a Cobra.

Small, lightweight, and worth its weight in gold!! Not only does the jumpstart your car and emergency it also is a flashlight, I can charge your phone and buy on the go. After by myself one and seeing how good it is about three more for everybody In my family. Anybody want to car should get one. And it also makes a great gift.

This portable charger has been a life saver. It has all the features our large one has but is so much more convenient. Easy to leave in the console of your vehicle. Easy to use. Not heavy like the larger ones. Absolutely love it. Plenty of power to jumpstart vehicles.

So far so good. Nice compact design makes it easy to carry around. So far had a need to start my ATV a few times and had no problems doing so. Have not had a chance to check it with a bigger engine but from how easy it was able to start ATV I would expect it to start a V8 with a weak battery.

My car battery was flaky over the weekend. And this held us over til we could get to the shop on tuesdat

I wasn't convinced this tiny battery held enough power to start my car but just days after purchasing the battery my car battery died. Within minutes, the battery transferred enough power to start my car. And there was plenty left for another time! I recommended this to my coworker and he's satisfied too.

This is an excellent product to keep in your car for those unexpected emergency

Plenty of juice for charging cell phone and tablet.

Pursued this to jump an older car the battery had died in. Goes with me everywhere, used it numerous times to help out folks needing a jump. Great product to have - true workhorse.

With this jumpjack I no longer have to buy rspensive batteries for all of my yard equipment. I simply use the jumpjack instead. It also charges my mobile phone when I am away from an outlet or need to take it with me. It’s a real money saver!

I really like this it's small device with so much power

used it to charge my phone and it worked well. it also comes with a flashlight that is useful as well!

I hope I'll never have to use this to jump start my car, but seems to be well constructed. Something I didn't know about this when I ordered it was that it has a USB port and a flashlight. The USB port didn't surprise me, but the flashlight did. I didn't read the product description before ordering. I bought it when it was offered as a daily deal. So I might have some use for this outside the rare dead car battery.

Bought it when it was a deal of the day for a great price. Haven’t needed it yet but nice to know it’s there if I do.

I've never jumped a battery before like this and was a little nervous. It was so quick an easy that I was back in my car and driving off in a matter of minute. It was nice not having to call someone for help!

It looks small but it packs a lot of punch when your car battery dies on you along with enough power to charge a couple of my iPhone and iPad devices. I believe everyone should have an emergency backup power for your car battery and mobile devices.

I owned the previous version of this charger and it worked very well. The biggest difference with this one apart from the physical size, darker color and higher battery capacity is that it comes with a nice case and that you have to charge it using a wall charger as opposed to charging it via a USB cord which is understandable due to the higher capacity. I have a 20,000 mah portable rechargeable device I use for my electronics that uses a USB cord to charge it and it literally takes 24+ to recharge it after being depleted so having the standard charging wall plug in cord is necessary in this case.

This works great. Never a missed charge. For the money this is worth it.

This was exactly what I needed when my battery died and no one was there to jump my car. The device came pre-charged and I was able to jump my car with the first attempt. I highly recommend this product.

Great charger. like the size. fits easily in the glove box of car.
