Marshall Islands to Guinea-Bissau: Complete Plug & Adapter Guide (2026) Adapter Needed

Traveling from Marshall Islands to Guinea-Bissau means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Guinea-Bissau so you can keep all your devices charged and ready.

There's no plug compatibility between Marshall Islands and Guinea-Bissau. Marshall Islands devices use Type A/B connectors, while Guinea-Bissau sockets are Type C. An adapter is a must-have for this destination.

Voltage is another key difference. Marshall Islands uses 120V while Guinea-Bissau uses 220V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

Don't forget that Guinea-Bissau hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
