What is this rather large inverter that is installed in my 2021 400 Boondock supplying power to? The only thing I know about is the 110 outlet next to my bed that supplies 110volts, without shore power, on battery alone. Is there anything else?

Isn't that the inverter/charger? you need that in order to charge or use your battery

No, the charger is in the WFCCO under the sink. It does two things, converts 120 to 12 and charges the batteries. The blue inverter above is just an inverter.

Typical 400 Inverters supply the Bed Cubby and Bed Area Television outlets

I have a 2021 400 BD and am not aware of a television inverter outlet. Our television so far as I could tell was strictly DC powered, and there is no AC outlet anywhere near where it was located (I removed the television and replaced it with a DC charging station).
The only inverter outlet in our trailer is in the bed cubby.2021 400 BD / 2016 VW Touareg / Austin, TX -
@CruiserCamperChris the picture of your converter shows it to be a modified/improved Powermax converter/charger, not the stock WFCO.

@CruiserCamperChris yes, the only outlet the inverter supports is the bed cubby. I can also confirm that the power supply for the television is also 12 volts. I use it as a power supply for my rear view camera when traveling.2021 Tab400 boondock, 2019 Jeep Grand Cherokee Trailhawk

@Binghi we also have a 2021 400 and yes the television is a 12v television and there is no 120v outlet under the television. I believe they had that in earlier models, then removed it, then added it again to later models. On ours the bedroom cubby is the only on powered by the inverter. Having an inverter powered outlet under the television would be very nice and I've mulled around with adding one.2021 T@b 400 BD "Vixen Gail"

The inverter outlet I want is the one over the kitchen sink and counter. That would be great to power an electric kettle for coffee and tea when you’re boondocking.2021 400 BD / 2016 VW Touareg / Austin, TX
