Should a Relay be Used With Wagan Power Inverter

Question

Question:

I have an OEM switch for my vehicle, but its only rated at 3 amps. Id use it to control a relay to apply/remove power to the inverter. Can you recommend a suitable relay for this?

Though I can see why you might think you need a relay, I do not recommend using one with the Wagan Power Inverter with Three AC Receptacles # WC3720.

This inverter has a simple On/Off switch; I assume you want to use a relay to conserve power from your battery but the same thing can be accomplished simply by turning the relay off. Just be sure to use the correctly rated fuse and wire gauge for the length of wire you need (which is included in the installation manual I've linked) to get the best performance from the inverter.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
