But not the large South African plug). This adapter does not change the Voltage. Please check the voltage standard for the travel destination and use a Voltage converter with the adapter if needed. (example, Europe use mainly 230 Volts). Many electrical devices such as AC/DC chargers for Laptops, cameras etc. allow a multi range Voltage (110-240 Volts) and eliminate the need of a Voltage converter. Sometimes electrical device have a switch for either 120 or 230 Volts (remember to set back! ). Please check the specifications on your equipment. Powering a 120 Volts device with 230 Volts can destroy the equipment and cause fire.
