From Tonga to Portugal
When travelling from Tonga to Portugal: None of your Tonga plug types fit in Portugal. You will need a travel adapter. Voltage is different (240V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency is the same at 50Hz.

About electricity in Portugal
Portugal runs on 230V/50Hz with Type C and F sockets, the standard continental European setup.
Grid & history
Portugal has one of Europe’s highest renewable shares: hydro, wind, and solar together cover most of the year’s demand. Strong interconnects with Spain mean Iberian outages are rare, though when they happen they tend to affect both countries (as in April 2025).
Availability
The grid is highly reliable. Madeira and the Azores run on local grids, but supply is steady.
Sockets & hotels
Type F (Schuko) is the standard, and Type C plugs slot in without an adapter.
Energy mix
Hydro and wind dominate.
Practical tips
- A European C/F adapter works everywhere.
- Voltage is the standard 230V, and modern chargers handle it.
