    Presumably, it means "Auxiliary Power Unit", which is a term that might be used by ex-military and prepper-type people from what I have found.

    Actually, an APU is an auxilliary power unit, which is usually used aboard an aircraft. It is a power source that is built into the air frame in case no external power source is available.
