In Chile the standard voltage is 220V and the standard frequency is 50 Hz. The standard voltage in the UK is 230V which means you can use all your electrical devices in Chile without any problems or the need for a voltage adaptor. The standard voltage in the US is about 120V, so travellers from the states may need to use a voltage adaptor in Chile. Nowadays most devices such as mobile phone chargers, USB chargers and laptop chargers are multi voltage which means they will switch automatically to the network voltage. However, some high power devices such as hair dryers don’t usually handle different voltages. Always check the label to see what voltage range the device works within. If you try to use a device with the wrong voltage it will most likely break.
