Costa Rica to Comoros: Complete Plug & Adapter Guide (2026) Adapter Needed

Planning a trip from Costa Rica to Comoros? One of the first things to sort out before you travel is whether your electronics will work at your destination. Power outlets, plug shapes, and voltage standards vary around the world, and Comoros is no exception.

There's no plug compatibility between Costa Rica and Comoros. Costa Rica devices use Type A/B connectors, while Comoros sockets are Type C/E. An adapter is a must-have for this destination.

Be aware that Costa Rica runs on 120V at 60Hz, while Comoros uses 220V at 50Hz. This voltage difference matters for appliances like hair dryers, curling irons, and electric shavers that aren't dual-voltage. Check the label on your devices. If it says "100-240V," you're fine. Otherwise, you'll need a voltage converter.

Don't forget that Comoros 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.
