I have a big 220v outlet in my wall where an old in-wall air conditioner was removed. The 220v outlet has power but is basically useless as is.
I imagine there must exist some sort of adapter I could plug in that would convert the outlet from 220v to a standard 110v receptacle, possibly even two 110v outlets, each on a different pole.
Unfortunately I've yet to find anything. Searching inevitably leads to adapters designed for international travel which won't work because 220v in Europe (and elsewhere) is single phase and 220v in the USA are two 110v lines in opposite phases with a common neutral line.
