Indonesia: round pins only, no exceptions.
Indonesia is the Southeast Asian country that will not take your plug. Where Thailand, Vietnam and the Philippines all have sockets that swallow flat American pins, Indonesia is pure European round pin — Type C and the grounded Type F — at 230V, 50Hz, from Jakarta to Bali to Lombok.
The specification, in one table
| Item | Indonesia |
|---|---|
| Plug types | C (two round pins, ungrounded) and F (Schuko, two round pins plus side earth clips) |
| Voltage | 230V |
| Frequency | 50Hz |
| What fits | Europlug and Schuko plugs; any adapter sold for continental Europe |
| What does not | US Type A and Type B flat pins, UK Type G, Australian Type I — none of them |
Type C and Type F are interoperable in one direction: a two-pin Type C plug drops into a recessed Type F socket and works, minus the earth connection. That is why one inexpensive adapter is enough for a whole trip — but it also means a grounded appliance can end up ungrounded without any visible sign.
230V, and the line of text that settles it
Read the input specification on the charger body before you pack it. 100–240V ~ 50/60Hz means the device was engineered for Indonesian mains and will behave identically to how it does at home; you are changing the shape of the plug, nothing else. A brick that says only 120V cannot be used here at all, adapter or no adapter, because the adapter passes voltage through untouched.
This is the entire adapter-versus-converter distinction. An adapter is a shape change and weighs almost nothing. A converter is a transformer that actually reduces 230V to 120V, weighs a lot, is rated in watts, and exists for heating elements and motors. The comparison is laid out at travel adapter vs converter.

Works as-is vs needs a converter
Works on a plug adapter alone: phones, tablets, laptops, camera and drone battery chargers, dive-light chargers, e-readers, power banks, electric toothbrushes, cordless shavers, USB fans. Every one of them is a switching supply with a 100–240V range.
Needs a converter or a dual-voltage replacement: hair dryers, flat irons, curling wands, travel kettles, US-market corded appliances with heating elements or AC motors. Replacement beats conversion nearly every time on a long trip — a dual-voltage travel dryer weighs a fraction of a transformer that can carry one.
Planning a route through the region? Singapore and Malaysia use Type G, Thailand uses hybrids, and Australia uses Type I — four shapes on one itinerary, which is the argument for a universal adapter rather than four separate plugs. Full index: plug types by country.

FAQ
What plug adapter do I need for Bali?
The same one as the rest of Indonesia: a Type C round-pin adapter. Indonesian sockets are Type C and Type F, and a Type C plug fits both.
Do US plugs work in Indonesia?
No. Unlike Thailand, Vietnam and the Philippines, Indonesian sockets take no flat pins at all. You need a round-pin adapter for every socket in the country.
Is Indonesian voltage safe for my laptop?
Yes, if the charger reads 100 to 240 volts, which every US laptop and USB-C charger does. Indonesia's 230V at 50Hz is inside that range.
Can I use my European adapter in Indonesia?
Yes. Indonesia uses the same Type C and Type F sockets and the same 230V supply as most of continental Europe, so one adapter covers both.
