In Timor-Leste, they use Type C, E, F, and I plugs and sockets. The mains voltage is 220 V, and the frequency is 50 Hz.
So, you’ll definitely need a travel adaptor in Timor-Leste. Their plugs and sockets aren’t the same as our Type G back in the UK.

Sockets in Timor-Leste
In Timor-Leste, you’ll find Type C, E, F, and I plugs and sockets.
Type C

Type C sockets have two round pins and no grounding. Unlike Type G, they take a slimmer plug without an earth pin or fuse.
Type E

Type E sockets have two round pins and a hole for the socket’s earth pin. UK Type G plugs do not fit into Type E sockets.
Type F

Type F sockets have two round pins with two earth clips on the side. UK Type G plugs do not fit into Type F sockets.
Type I

Type I sockets have two flat angled pins and sometimes a vertical earth pin. UK Type G plugs do not fit into Type I sockets.

No adaptor once you’ve landed? Airports and local shops are an option. But nothing beats the peace of mind of having your own ready to use.
Timor-Leste is commonly visited alongside Indonesia and Australia. It’s smart to check plug types — island nations often follow their own systems.
Do You Need a Voltage Converter?
You’ll only ever need a voltage converter if your device’s voltage doesn’t match the country’s. In Timor-Leste you won’t need one — the mains voltage is roughly the same as in the UK.
Always check the mains voltage label before plugging in abroad; if it shows ‘100–240 V, 50/60 Hz’, you won’t need a converter.

Top Travel Essentials to Take With You
It’s often the overlooked bits of kit that help the most. A luggage scale spares you the stress of overweight bags, a power bank keeps you going when outlets are scarce, and packing cubes keep everything in its place. We’ve tested them on the road, and they really earn their keep.
