I have a standard 110 outlet with two plugs. Is there any way to convert the two 110s to one something a bit stronger? I have a 6-20 at my office that does 10 miles per hour and that would be perfect for me at home. Seems like it's possible since there's two plugs and 4 wires and it can obviously handle two things plugged in at once. My box is too far from the garage to practically get thicker wiring. Any thoughts appreciated.
