Shown here is a absolute neccesity to anyone with accessory lighting. Leave your lights on again? this little guy is more capable than ever with 21800mah 5000a starting capabilities. We put it to the test at the last truck show we were at jumping 10+ trucks and still having half a battery. also included in the pack is 2 different work lights, phone charger plug in and 150 psi air compressor. with small design I slip mine under my back seat so im never left stranded and I highly recommend everyone else does to. Get lit up with AGR!!!!!!!
