IF you are talking 110 volt multi-outlet surge suppressor type power strips like you would use on a computer, or whatever, certainly. I plug my computer into a surge suppressor power strip as a matter of routine. I dislike the stench of fried computers...
The 110 volt AC duplex outlets in an Airstream are much the same as the outlets in your house.
Of course, as with your house, you don't want to overload the circuits, or cause a shock hazard. With an Airstream or a house, you are limited to how many amps you can draw without popping a breaker...
Keep in mind that running the Air Conditioner in a 30-amp Airstream does not leave much power for other things. A primary problem would be trying to use a hair dryer at the same time the AC is running--pretty much bet you will pop a breaker and have to reset it after you turn one or the other off...
