I picked up this "PowerStation" at Costco for $75. Inside is a 18ah sealed battery, it has it's own float charger, USB port, air compressor, light, and 12v cigarette plug. All it needed was Anderson Powerpole. Anyway, here it is, it's to the back of the box near the 110v in. Pretty happy with it, and it's fairly light.
