I've hooked up a monitor to run on 12V and have successfully tested it both on an isolated battery, and through my cigarette lighter socket for ~5 minutes. It works well, but I'm concerned about burning out the wiring.
Aside from draining the battery, is there anything to be concerned about from running a 3 amp device at 12V?
