FYI, this line of Duracell power packs also retail under a number of other different names (two I've seen are AC Delco and Eliminator, the last of which is linked earlier in this thread). I was originally after the AC Delco version that includes an air compressor, but I couldn't find one for under $150, which made the Cobra an easy decision.
