Indonesia plug type and voltage: charging on the road
Round pins, 230 volts, and the power bank rules for the flight.
By the Local SIM Indonesia team, checked October 3, 2026
The short answer
Indonesia runs on 230 volts at 50 hertz, and most sockets take the round-pin European type C and F plugs; other plugs need an adapter. A charger marked 100 to 240 volts works as it is; a single-voltage device, like a hair dryer, needs a converter. Power banks travel in the cabin bag only, at the 100 Wh limit or with airline approval.
- Voltage: 230 volts at 50 Hz, the standard across the country.
- Sockets: round-pin type C and F, the European two-pin design; a plug of another shape needs an adapter.
- Chargers: most phones and laptops are marked 100 to 240 volts and work as they are; a single-voltage device, such as some hair dryers, needs a converter.
- Where to charge: hotels and airports have sockets free to use, almost all restaurants have one, and the trains put a plug in every class.
- Power banks: cabin bag only, at the standard 100 Wh limit, or up to 160 Wh with the airline's approval; keep the terminals from touching metal.

Good to know (Packing)
Power banks in the air
Power banks travel in the cabin bag only, and a bag checked at the gate must give them up: they stay with you in the cabin. The standard limit is 100 Wh, up to 160 Wh needs the airline's approval, and airlines can set stricter rules.
Single-voltage devices
A hair dryer or straightener built for a single low voltage, such as 110 to 120 volts, needs a converter, not just a plug adapter; if the label shows a single voltage, leave it at home.
Where you can charge
Hotels, airports and almost all restaurants have sockets you can use, and Indonesia's trains provide a plug in economy and business class alike.

What is the Indonesia plug type?

Do I need a voltage converter in Indonesia?
Not for a charger marked 100 to 240 volts: Indonesian mains is 230 volts, and those chargers handle it. A device marked for a single low voltage, such as some hair dryers, needs a converter, and the tourism ministry advises travellers from 110 to 120 volt countries to bring one.
Can I bring a power bank to Indonesia?
Yes, in the cabin bag only. The standard limit is 100 Wh per battery, larger ones up to 160 Wh need the airline's approval before the flight, and airlines can set stricter limits of their own.
