I don't think there's any smarts built into these, they're cheap public model product of lower quality than the regular low quality cig adapter they normally use

Some electronics are sensitive enough to "hear" alternator noise which indicated that the engine is on. Course that doesn't work on hybrids. And I REALLY doubt this thing has anything like that inside.

Thinking about it, those switching regulator chips often have an enable input on one pin, maybe you can just connect that to the 12v via a voltage divider so that it only enables at alternator voltage. Still wont work on hybrids.
