Hey guys thought you might be able to help me out with this one.. I've got myself an aerobed for camping trips which comes with a rechargeable pump - this pump can be charged from the AC adapter or operated directly from a 12v lighter adapter. What it tells my I can't do is operate the pump when plugged into AC or damage may result.. I can't really figure out why they've done this but am looking for a workaround.
The car adapter outputs 12v and is rated to 6.6 amps, the wall adapter outputs 12v and is rated to 400mA. Am I able to trick the pump into not damaging itself when operated from AC by just using a 12v adapter rated to 6.6 amps?
