I got the AC! warning alert on the display and the inputs would not reflect the wattage being ued. When I had all the items shown plugged in, there was no issue, only after I decided to plug only the AA charger into the AC port did I see the error. The load did not exceed the capability of the battery.

I ended up taking he battery out and reseating the connections and thus fare seems to show the wattage used now. I do see the AC! icon appear momentarily when turning on the port, not sure is this is normal.

Also I noticed a red and black wire taped to the side with a rubber cap. Not sure if this is grounding wire?

You do pay a premium for the design of the built in pure sine wave inverter and LCD display. You could build one yourself, but would not be as elegant as this design. Which I don’t mind paying for.
