I can charge any battery powered appliances like that at home. Propane is only sold per bottle, not every petrol station has them(in fact - majority don't), you have to rent the bottle each time, the thing is stupidly heavy and has various restrictions on storage(can't park a car with it in an underground garage for instance, my insurance does not allow me to keep it inside my garage etc). Battery powered is just so much easier unless you're using it commercially and go through a lot of gas I guess.
