  • Great jump starter in the palm of your hand
It’s a great jump starter that packs a lot of features in such a small device. Great capacity, led displays voltage and wattage. Covered inputs and outputs. The light illuminates the engine bay to be able to connect the clamps in a low light situation. It’s so small that you can fit it in a backpack and use it as a power bank as well. Overall it’s another great product by lokithor. ... show more

  • Compact Jumped
I love the size of this thing. It will be great to bring on trips when size is a constraint. It works great, Ive been using to it jump equipment. Has an override feature so it can jump items with completely dead batteries.

  • Excellent quality jump starter to carry
This is an excellent jump start unit to carry around for emergencies, it adds peace of mind. It's built very solidly, and includes additional features like a flashlight and can charge your phone when traveling. It charges via USB, so is easy to plug in, and seems to have great power. I don't doubt this would revive the car once or twice in an emergency, maybe even more as the battery life seems great. It's compact and easy to carry in a bag or stick in the backseat. For being so small and lightweight, it packs a punch and is very easy to use. Would recommend anyone to have one for emergencies, especially in colder areas. ... show more

  • Worked on the first try
I've had this unit for a few weeks, but only today got a chance to try it for real. Our next door neighbor's Honda CR-V battery was dead, and AAA said they would be a while due to the holiday. I welcomed the chance to try out this jump starter. Biggest challenge was finding the hood release on the car! After that, we attached the cables to the battery, and hit the "Start" button. The unit did its countdown, then went green - good to go! My neighbor got in and started the car on the first try, now off to get a new battery. This was super convenient. The car was actually parked face in to the garage, so we would have needed extra long jumper cables to jump start from another car. Super happy how this worked out, and I'm getting two more of these for my kids to have on hand - great for emergencies! (If I had to do it again, I'd buy the bundle that includes a nice storage case.) ... show more
