Please note that our travel adapters do not convert voltage. The travel adapters simply adapt plug from your electronic device and let you connect the device to an electric outlet in a different plug type socket. These adapters do not convert the voltage coming in from the socket. You’ll need to make sure that the device you are connecting using an adapter is compatible with the voltage of the country you are using it in. However, common travel items such as laptops, smartphones, cell phones, tablets, iPad etc are compatible with worldwide voltage and have the input voltage rating of 100-240V and do not require the use of a voltage converters.
Voltage converters or transformers actually convert the input voltage of 220-240V to 110-120V or from 110-120V to 220-240V for devices that do not support the worldwide voltage range of 100-240V. Voltage converters/transformers come in various sizes in their power rating from 50W to up 20,000W. Depending on what kind of item you are looking to use, you’d need to purchase an appropriate size voltage converter or transformer. Some examples of devices that are only available in single voltage are blenders, mixers, power tools, coffee machines and even some hair dryers or hair straighteners. When traveling with these items carefully look at the spec rating on the item and look for INPUT voltage range and if its only single voltage (for instance US devices are 120V only) then look at the power rating in WATT and then use an appropriate size voltage converter or transformer with your device if you are travelling to a 220V country.
