While staying at our Washington home base, we “moochdocked”, plugging our coach in to the house power.

15 amp power from a house isn’t enough to run air conditioners or multiple heavy-draw gadgets like the microwave, but is enough to keep our fridge going, power computers, and keep the batteries charged for the 12 volt lights and such.

To do this, I previously used a 15-to-30 amp adapter and a 30-to-50 amp adapter (“dogbone”). But this time I bought an adapter that goes straight from the 15 amps to 50 amps plugs, along with a surge protector:

I also bought a heavy-duty 30-foot, 50-amp extension cord to reach from inside the house to our coach (in addition to the cord on the reel built in to the coach):

I plugged the power cord from our coach into my Power Watchdog smart surge protector, as usual, then connected that to the extension cord, which went through a window into the house:

And into the adapter, which was plugged in to an outlet in the house:

(We did try plugging in to an outside outlet, but it popped the breaker, as that was on the same circuit as a freezer in the garage.)

We had to be careful not to use too much power at a time. The Power Watchdog was useful in monitoring this, since it has an app that connects via Bluetooth that shows the current power usage. But we managed.

Staying at campgrounds, we won’t need this adapter and extension cable, but useful to have when moochdocking.
