Guinea-Bissau to Cuba: Complete Plug & Adapter Guide (2026) No Adapter Needed

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

Both Guinea-Bissau and Cuba use Type C plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

Voltage is another key difference. Guinea-Bissau uses 220V while Cuba uses 110V. 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.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Cuba specifically, look for one that supports Type A/B/C/L outlets. USB charging ports built into the adapter are a nice bonus.
