I want to power Christmas lights (without a nearby power outlet) for at least 2 hours and was wondering how to go about it. The lights run on 120V AC and draw .34A per strip (about 40 watts) and I want to use 5 strips. I could buy a 12V battery and power inverter to supply 120VAC, but I would like to see if there's a cheaper or easier way.
I could rig up some AA batteries in series and parallel to supply 12V to a power inverter, but since batteries lose voltage as they drain, would I need to buy some sort of "voltage booster" to maintain the 12V? Could I even use a single portable phone charger battery (3.6V) and a voltage booster instead? Or is there some other easier way to do all of this?
