How To Power a 12 Volt Cooler Off a Trailer Battery
Published 04/12/2023
Question:
I have one of these Hopkins HM47675 that I use with my truck, Works great to power a 12 cooler while in the bed of the truck. Wondering if you sell a similar item that would allow me to power the same cooler from the trailer side connection?

Expert Reply:
For powering your 12 volt cooler of the trailer battery you will want to install a 12 Volt Outlet Kit # RM-9332 directly to the battery. There is not a connector like the Hopkins # HM47675 which can connect to a trailer side 7-way and give you a 12-volt outlet. The trailer connector will typically have a resistor or charger which will prevent the power from going back through the connector.
