North Korea.

220/110 V · 50/60 Hz on Type C, Type F, Type A.

The IEC records both 220 V and 110 V supplies, at 50 and 60 Hz, arriving through European C and F sockets alongside American-style Type A — so nothing about an outlet can be assumed. In practice foreign visitors meet 220 V C or F sockets in hotels. Power availability itself is the bigger constraint.

The voltage window

A nominal 220 V supply may legitimately sit anywhere between 198 and 242 V (±10%); A nominal 110 V supply may legitimately sit anywhere between 99 and 121 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.

Coming here from somewhere else?

Plug straight in — North Korea runs 220/110 V 50/60 Hz on Type C, Type F, Type A — and your 120 V appliances need to be dual-voltage or transformed, adapter or not.
