I was curious if anyone has experience with something like this. Seems like a decent option rather then tapping into an ignition on power source. Thinking about using it for a mobile radio. Seems like as long as I didn’t exceed the amperes a few devices could be connected to it.
Powerwerx DC Automatic Power Switch/Timer
Never turn on or off your radio(s) again! The APS-12 is basically a voltage controlled switch. When the vehicles engine shuts off, the unit senses the drop in voltage and starts the APS-12 timer to automatically shut off after 2 min. to 12 hrs.
