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.
Sierra Leone is often combined with regional trips to Liberia and Guinea. It’s a good idea to check plug types — standards can vary even between neighbours.
Sockets in Sierra Leone
Sierra Leone uses Type D and G plugs and sockets.
Type D

Type D sockets have three large round pins in a triangular shape. Unlike Type G, they lack a fuse and the pins are round rather than rectangular.
Type G

Type G sockets have three rectangular pins arranged in a triangular pattern, with a built-in fuse for safety. They are the standard used in the United Kingdom.
Do You Need a Voltage Converter?
Converters only matter when voltages clash. In Sierra Leone the supply is pretty much the same as the UK’s, so you’re sorted.
Make sure to look at the voltage label before travelling. Devices marked ‘100–240 V, 50/60 Hz’ will operate abroad without any converter.

The right travel gear can save you money, stress, and time. A luggage scale means no nasty shocks at check-in, a power bank keeps your phone ready for maps and tickets, and packing cubes make it easy to find what you need. We recommend them because they work.
