The P12 chargers work perfectly with the Blue Sea “Sure Eject” which automatically eject the shore-power cord when your vehicle’s engine starts. If you have given up on auto-ejects due to poor reliability, give the Sure-Eject a try. While it fits into the standard cutout that a Kussmaul Auto Eject uses, the Sure-Eject uses a motorized ejector for better reliability. Also, it uses 1-handed cord insertion, and has an indicator light on the cover so you know when power is flowing to the truck. See the Auto-Eject Shore Power sockets web page.
