Tonga to Dominica: Complete Plug & Adapter Guide (2026) Adapter Needed
Getting ready for your journey from Tonga 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 Tonga plugs (Type I) 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.
The voltage and frequency in Dominica (230V, 50Hz) are close to Tonga (240V, 50Hz), so your appliances should work without a 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.
