The entire electrical system (including the A/C) in the camper/motor home is a 110 volt system. The A/C requires a 30 amp circuit and that is why the power cord has the end that it does (it’s not a 220 volt end)…because if it had a standard two prong connector it could be plugged into a 20 amp 110 volt service and pop the breaker or worse. You can, however, as mentioned above purchase an adaptor (+/- $10 at any RV supply) that you plug the unit into that will allow you to plug into a standard two prong 10 volt, 20 amp circuit. Everything should run fine, but if you try to run the A/C you may pop the circuit breaker. I hope this helps. P.S. If you try to plug the unit into a 220 volt circuit, you’ll fry everything reducing the value to zero.
