Electricity is 220V, 50 cycles AC. Note that electronics such as laptops and iPods (anything with a hard drive) are occasionally affected by altitudes above 4500m.

Plugs

Plugs have at least five designs: three-pronged angled pins (as in Australia), three-pronged round pins (as in Hong Kong), two flat pins (US style but without the ground wire), two narrow round pins (European style) and three rectangular pins (British style). US plugs work in Tibet without the need for an adapter.
