Trinidad and Tobago to Dominica: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Trinidad and Tobago to Dominica? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

Your Trinidad and Tobago plugs (Type A, B) won't fit Dominica's outlets (Type D, G). You'll want to grab a universal travel adapter or one specifically designed for Dominica before you depart.

Be aware that Trinidad and Tobago runs on 115V at 60Hz, while Dominica uses 230V 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.

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