Tonga to San Marino: Complete Plug & Adapter Guide (2026) Adapter Needed

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

The voltage and frequency in San Marino (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 San Marino specifically, look for one that supports Type C/F/L outlets. USB charging ports built into the adapter are a nice bonus.

Frequently Asked Questions

Yes. Tonga uses Type I plugs and San Marino uses Type C/F/L. Since these are incompatible, you will need a travel adapter.
