Sockets in the Galápagos Islands
In the Galápagos Islands, you’ll find Type A and B plugs and sockets.
Type A

Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.
Type B

Type B sockets have two flat parallel pins plus a round grounding pin. Unlike Type G, the pins are thinner and there’s no built-in fuse.

No adaptor with you and already abroad? You’re not out of options — many airports and local shops sell them. Still, bringing your own is the simplest way to avoid paying over the odds or ending up with something that barely works.
The Galápagos Islands are usually visited alongside mainland Ecuador and sometimes Peru. It’s a good idea to check the plug info for those places too — they don’t always match.
Do You Need a Voltage Converter?
You’ll probably need a voltage converter in the Galápagos Islands for certain devices, as the mains supply there doesn’t match ours. In the UK we use 230 V, so the voltage isn’t the same.
Check the mains rating on your device before travelling. A mark of ‘100–240 V, 50/60 Hz’ means it’ll work abroad without any converter.
