Moki Travel Adaptors DO NOT convert voltage. Ensure appliance you plan to use meets the voltage requirements for the region and check with appropriate foreign authority if any concern. If your local adaptor or appliance specifies on its label plate 100-240V, 50/60Hz it should be appropriate to use in any region without the use of a voltage converter. Any unmarked appliance should be considered unsafe and should not be used. Some regions / countries use multiple socket configurations.
