For a 110v extension cord, and to avoid the error code, is 15 amp rated cord enough or do I need to get the 20 amp ones?
I keep a 12 gauge extension cord in the trunk for emergencies, it works fine for charging. Household wiring is generally 14 gauge for 15amp and 12 gauge for 20 amp. You won't have a problem if the extension cord is the same gauge as the wires in the wall. Don't go higher than 14, and I'd use 12 to be safe.
