That is true Jim, The outlets require AC to produce the USB's charging current.
We do have two ways to power our AC outlets from the battery
. We have a rarely used 1200 Watt Inverter and a cigarette lighter/12 volt socket, 150 watt inverter. The 150 watt Inverter is frequently used every night we boondock. We also carry a secondary one in the car.
We often use the 150 watt Inverter to power our TV and Sat Receiver when boondocking
. Assuming we shutoff the Convertor (never on when boondocking), electric hot water and Air Conditioner (never on when boondocking). we can easily power every outlet from the 150 watt Inverter and as a result power our USB ports, TV and Sat dish receiver.
The sum total of the Sat Reciever, TV and USB ports is well less than 150 watts.
Usually when we go to bed we unplug the 150 watt Inverter after we're done with TV. Of course one can not leave this Inverter plugged in powering all outlets and plug in a coffee pot for example or a hair dryer. it definitely takes some consciousness.
