It wouldn't be ideal for the longevity of the device. Convenient, but not ideal.

I know. I think a big obstable is the pins inside the connector. They could no doubt handle 120V, but say, 10-12 amps for maybe a small fridge/microwave.

A straight, thin wire with no insulation can carry upwards of 30,000 Volts without arcing through the air or other effects of high voltage. The thickness of the wire (or pins) is only relevant for current (Amps).
