Didn't the first wave of these have the Champion brand name? I haven't seen them in years either.
Really small jump boxes are becoming popular now. I bought one back when they were a bit newer and no reviews existed for such a product. Luckily it has been absolutely great. I see no reason to carry around the larger portable type units (almost the size of a car battery), let alone a roll around monstrosity, when these mini jump units work so well. I wouldn't bring it to start a diesel though...
