Sockets in Guinea
In Guinea, you’ll find Type C, F, and K plugs and sockets.
Type C

Type C sockets have two round pins and no grounding. Unlike Type G, they take a slimmer plug without an earth pin or fuse.
Type F

Type F sockets have two round pins with two earth clips on the side. UK Type G plugs do not fit into Type F sockets.
Type K

Type K sockets have two round pins and a grounding pin that sticks out from the socket itself. UK Type G plugs do not fit into Type K sockets.

Realised abroad that you’ve left your adaptor behind? You’ll often find them in airports and shops nearby. Still, carrying your own is cheaper and more reliable.
Guinea is usually visited together with Sierra Leone and Guinea-Bissau. Plug types and voltage can vary, so it’s worth checking before you travel.
Do You Need a Voltage Converter?
You don’t need to worry about a converter in Guinea; the voltage is virtually identical to what we use in the UK.
Always check the voltage label before you plug in abroad. If it reads ‘100–240 V, 50/60 Hz’, your kit will work just fine without a converter — most modern laptops, tablets and chargers already do.

Top Travel Essentials to Take With You
Beyond your adaptor, a few clever travel items can make life on the road so much easier. A luggage scale saves you money, a power bank keeps you powered up, and packing cubes keep your clothes tidy. They’re simple, practical, and genuinely useful.
