United States to South Africa Power Adapter Guide

United States runs 120⁠V and South Africa runs 230⁠V. You need a Type M/N plug adapter; check each input label before connecting; a converter is not suitable for every appliance.

Caution: United States runs 120V and South Africa runs 230V. A plug adapter changes the shape, not the voltage — a mismatched appliance must not be connected directly. High-power heating appliances should be replaced with a suitable local model; check both manufacturers before considering a converter.
