As you can see, this can be a big mistake. Not knowing the voltage can result in an expensive air conditioner replacement. Low voltage means high current in the compressor motor. Enough to burn one up. Not to mention frying the magnetron in your microwave.
Volt meters are CHEAP insurance:
Amazon.com: Prime Products 12-4055 AC Voltage Line Meter: Automotive
Amazon.com: Camco 55263 120V AC Line Voltage Meter: Automotive
Any voltage in the red will damage your inductive loads (air conditioner and microwave) over time, cause unreliable operation in your electronics (radio, TV and computers), and make resistive loads (water heater, refrigerator (on AC) and your converter) woefully inefficient.
Had I plugged into the one that read "high", it would have cost me about $3000 in repairs.
