Keep your loved ones safe

Perfect size to keep in your vehicle for emergencies or just use at home when needed. I gave it to my mom as she travels a lot for doctor's appointments and I get worried she might end up stuck somewhere without help. Very light weight and easy to use.

On one of the coldest days of month while I was about to leave work a coworker's car wouldn't start so he asked me to move my car next to his and give him a jump. I said I've got something better and I got the car battery jump starter out the trunk and did the connections and his car started right up. It does what it supposed to do and the price was good. I ditched my jumper cables because the Tenker car battery jump starter is all I need. I recommend it.

Powerful

I kept having battery trouble and asking my co workers for a boost so I decided to purchase a jump box. It has saved me several times already. It works quick. It gives me a piece of mind knowing I don't have to wait for help is my car decides not to start.
