Guinea-Bissau to Sierra Leone: Complete Plug & Adapter Guide (2026) Adapter Needed

Heading from Guinea-Bissau to Sierra Leone? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Your Guinea-Bissau plugs (Type C) won't fit Sierra Leone's outlets (Type D, G). You'll want to grab a universal travel adapter or one specifically designed for Sierra Leone before you depart.

The voltage and frequency in Sierra Leone (230V, 50Hz) are close to Guinea-Bissau (220V, 50Hz), so your appliances should work without a converter.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
