What plug sockets does Gibraltar use?
Short answer
Gibraltar uses UK-style three flat-pin sockets (type G) at 230V. Visitors from the UK need no adapter, while visitors from Spain and the rest of Europe need one.
Detailed answer
Most modern phone and laptop chargers work on 230V without a converter. Because Spain uses two round-pin sockets, travellers staying on both sides of the border may need adapters for each.
