Electricity access and reliability
– Destinations / countries with power cut off times
There are basically two main systems that are used –
110 volt (actually 100-120 volt) – used in USA, Canada, Japan (and some parts of Spain)
220volt (actually 200-250 volt) – the rest of the world.
In simple terms, the power supply available at the socket is roughly twice as powerful in 240 volt countries as in 110 volt countries.
Electrical appliances are manufactured to be used at 110 volts, or 220 volts or both (they may have a 110-220v switch, or work automatically on either).
If you have a 220 volt appliance, and you plug it into a 110v source, the product will not receive as much power as it was designed to use – therefore it will work slowly or not at all.
If you have a 110 volt appliance and plug it into a 220 volt power source, the product will receive more power than it was designed to use – this will cause damage to the product, the protective fuse and/or the power source!!
It is a good idea to travel with dual voltage appliances – i.e. those that can work on 110 or 220 v systems.
