Jump Starter 5500A, 12V Car Battery Jump Starter with USB Quick Charge (Up to 10.0L Gas or 9.0L Diesel Engine), Battery Booster with 3 Modes Flashlight and Jumper Cable(Grey-5500A+Charger Block)

BUY THIS RIGHT NOW This charged to 100% right on my kitchen counter. Took less than an hour. I went outside this freezing morning, raised the hood of my heavy Lincoln suv, attached this red to black, and turned the key. My suv started immediately on the first try. I detached immediately then drove around and stopped at some stores. The battery worked fine at restart without needing another jump. This was so simple it seemed suspicious. You know how much a tow truck would have charged me? They'd take one look and know I'd pay whatever they asked just to be done and over with this inconvenience. This helped me do it myself. I am buying this for everyone I know.

This thing is a beast!! My 2023 Prius has been having issues in the cold weather. A coworker tried to jump me with their pack but it wasn't strong enough. This one can jump 4-5 times per charge! The power gets my car started in 30 seconds. I would recommend this to everyone to keep in their cars for emergencies. Compact, way easier to handle than cables, and you don't have to rely on anyone! The ONLY drawback on this is the length of cable, it's probably just enough for a standard battery but since my car is weird (no plug hybrid) my positive connection is in the fuse box and I have to pinch a ground screw for the negative. It works, but it could be easier. Overall, this is one of the best purchases I've ever made on Amazon.

Bought it for. Frend and it works very very well ...

I have used this twice once having a a little bit of juice and as soon as I hooked it up my vehicle cranked up instantly. I just recently used it on a -1degree temperature and my vehicle was completely dead and it started up after about 15 minutes. This small compact device was worth it.

Muy bueno ya lo he usado 2 veces con la bateria muerta.

Only lasted 1 charge cycle. I wrote this review saying it only lasted 1 charge cycle. The company reached out to me, asked a few questions to determine issue, then promptly issued me a refund. Very good response!

Actualy it works. My first attempts faild because I didn't follow instructions. After connecting clamps I should wait until red-green light turns into stable green. Then it started 3.5L Santa fe easily.

Fortunately I've not needed to use this but bought to have in the car incase I ever did. I like the concept and the option to also use as a backup power source for a phone if the power is out. The case is compact and easy to store in the boot.
