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.
Guinea-Bissau is usually visited together with Guinea and Senegal. It’s a good idea to check those pages too — plug types and voltage may differ.
Do You Need a Voltage Converter?
A voltage converter only helps if the supply is different. In Guinea-Bissau the mains voltage lines up with the UK, so there’s no need.
Before you plug in abroad, make sure to check the voltage label. Devices marked ‘100–240 V, 50/60 Hz’ can handle different voltages, so no converter needed.

Top Travel Essentials to Take With You
It’s often the overlooked bits of kit that help the most. A luggage scale spares you the stress of overweight bags, a power bank keeps you going when outlets are scarce, and packing cubes keep everything in its place. We’ve tested them on the road, and they really earn their keep.
