The current used in Gran Canaria and throughout the Canary Islands is 220 Volts AC 50Hz and plugs have two round pins as found on the European continent.
Travellers from the USA will require a voltage converter, however the higher standard hotels do have provision for 110 Volt appliances like shavers.
Travellers from the UK will require a plug adapter and this is best bought in the UK as they are hard to find in the Canaries, although if you do forget – El Corte Inglés department store is probably your best bet. Main sockets require round-pin plugs.
