    Game Saver

    I charged this up and put it in my car the morning of heading to tailgating. One of the people we were tailgating with, had their trunk open and the auxiliary power on for music for hours. When they went to start their car, the battery was dead. I brought out the booster pack, which was easy for them to use and worked like a charm. They canceled their call for the Auto Club and bought the same product the next day. Others there were intending to purchase their own as well.

  • Does it have an air compressor for your tires as well

    No, the GB20 is solely a Jump Starter and does not have air compressor capabilities. Please see the NOCO AX65 instead, as that is our combination Jump Starter + Air Compressor model.

  • It is safe for transport on comercial flights ?

    The GB20 is FAA-compliant and can be taken on a plane in your carry-on luggage. No lithium batteries are allowed to be checked in luggage. This Boost model is under 100Wh, the limit set by the FAA. We also recommend contacting the airline you are flying with to see if they have any additional restrictions. ** TSA has the ability to deny any item they deem unsafe at the time of check-in with airport security, regardless of the FAA regulations.
