Plug and Jump universal

Plug and Jump universal external power adapter (12/24V) for Cessna, Piper, Beechcraft. Verify that your aircraft has the 3 pin external power adapter (it is only on later model Cessnas such as N model. Not sure about earlier models). Note that it does not convert 12V to 24V, so you must supply the correct voltage. Also note that the external power receptacle typically doesn’t power avionics (as they are on a separate bus).

I bought it for $120+tax and it is now $140+tax new. I’ve only used it once or twice, as it is as new. Selling for $50 because you can purchase the Cessna specific adapter on Aircraftspruce for $74, so it seems a little overpriced.
