Tonga to Bosnia and Herzegovina: Complete Plug & Adapter Guide (2026) Adapter Needed

Getting ready for your journey from Tonga to Bosnia and Herzegovina? 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 Bosnia and Herzegovina's outlets (Type C, F). You'll want to grab a universal travel adapter or one specifically designed for Bosnia and Herzegovina before you depart.

The voltage and frequency in Bosnia and Herzegovina (230V, 50Hz) are close to Tonga (240V, 50Hz), so your appliances should work without a converter.

Don't forget that Bosnia and Herzegovina 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.
