Mexico.

127 V · 60 Hz on Type A, Type B.

Same flat-blade Type A and B sockets as the US and Canada, but the nominal supply is 127 V at 60 Hz — close enough that North American gear works without a thought. Older buildings often have only two-slot Type A outlets, so a three-pin earthed plug may need a cheater adapter. Europeans need an adapter and dual-voltage devices.

The voltage window

A nominal 127 V supply may legitimately sit anywhere between 114 and 140 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
