Can I use my United States plug in Indonesia?
A straight answer for United States devices on a Indonesia trip — plugs, voltage and frequency compared.
Adapter and a voltage check
Indonesia uses Type C and Type F sockets at 230 V / 50 Hz, so your Type A and Type B plug will not fit. You need a travel adapter, and any device that is not marked 100–240 V needs a converter.
Side by side
| United States | Indonesia | |
|---|---|---|
| Plug types | Type A and Type B | Type C and Type F |
| Voltage | 120 V | 230 V |
| Frequency | 60 Hz | 50 Hz |
| Socket standard | NEMA 1-15, NEMA 5-15, NEMA 14-30, NEMA 14-50 | SNI 04-3892.1.1-2003 |
What to pack
- A travel adapter from Type A, Type B to Type C, Type F — the shapes are incompatible.
- A converter (not just an adapter) for any device that is not marked 100–240 V.
- Nothing extra for frequency: chargers and laptops are unaffected, though mains clocks and older motors can run fast or slow.
- A second adapter if you travel with a partner — they are cheap and easy to lose.
