I have had the Smart plug installed on my Airstream trailer for a year and a half and it has been as advertised. It is a heavier duty and better looking alternative to the standard shore power cord and connection.

The cord is easy to handle and has an optional cover for the end of cord to prevent corrosion and dirt from getting into to the connections.

It slides straight in to the connection receptacle on the trailer and firmly locks into place with out any twisting or turning a plastic collar. The end of the cord has a blue LED light to let you know when you are hooked to power.

I would recommend SmartPlug to anyone wanting to upgrade their shore power cord and connections.“
