Well, not so much intelligent, but those that run off an alarm battery and are able to 'boost' a flat car or motorcycle battery from scratch.

There was a promotion around ten years ago on a shopping channel that mentioned these could start a car whose battery that was almost dead by leaving for a few minutes, but of course connecting a smaller unit in parallel with a low resistance sink is unlikely to assist unless there is some intelligence going on with the drain.
So, is there somebody out there that knows of the circuitry these things have inside, or can divulge the theory behind the 'magic' ?
