Cigarette Lighter Power Supply

[BrianG]

Most cars are rated for 14.4v from the alternator when the engine is running. A few might be a little higher, but not much. Most chargers have a 15v limit. If it happens to be higher, turn on your headlights or blower fan to suck a little juice and bring the V back down a tad.

i highly doubt that to be the case, ALTHOUGH, when i was using my esavage dual charger, i noticed it to get very hot when in the car and cool as the air when it was off my power supply. i never did run it directly off my battery though (which is 2-3yrs old)

but, could it be something to do with not being a solid voltage/current, and it ripples and this could damage the charger? i have no idea how they work, but thats why people suggest not using car starter/jumper pack thingys.
