It is one of the smallest items on a packing list and one of the most frustrating to forget: the right plug adapter. Arrive in Bali without one and your first evening can involve a hunt through a minimart for an overpriced travel plug. A couple of minutes of preparation saves the hassle, so here is exactly what Bali's electrical system looks like and what you need to bring.
Plug types: C and F
Bali, like the rest of Indonesia, uses the European-style two-round-pin plugs known as Type C and Type F. Type C is the standard two-pin 'Europlug', and Type F (the 'Schuko' type) is the same two round pins with extra side grounding clips. The two are interchangeable in practice — a Type C plug fits a Type F socket and vice versa — so a single round-pin European adapter covers you across the island.
If you are coming from the UK, Ireland, the USA, Canada, Japan, or Australia, your plugs will not fit Bali's sockets, and you will need an adapter. Travellers from most of continental Europe already use compatible round-pin plugs and usually need nothing at all.
Voltage and frequency
Bali runs on 230 volts at 50 hertz. This is the same standard used across Europe, the UK, Australia, and much of Asia, so devices from those regions work directly with just a plug adapter. The important caveat is for visitors from countries that run on roughly 110–120 volts, such as the United States, Canada, and parts of Latin America.
Adapter versus converter — the crucial difference
An adapter only changes the shape of the plug so it fits the socket; it does nothing to the voltage. A converter (or transformer) actually steps the voltage up or down. Most modern travel electronics — phone chargers, laptop power bricks, camera and tablet chargers — are 'dual voltage', meaning they accept anything from about 100 to 240 volts. Check the small print on the charger: if it reads '100–240V', you only need a plug adapter, even coming from the USA.
The danger zone is single-voltage appliances rated only for 110–120V, typically older or high-wattage items like some hairdryers, curling irons, and travel kettles. Plugging one of those straight into Bali's 230V supply with only a plug adapter will damage it, sometimes spectacularly. For those you need a proper voltage converter — or simply leave them at home and buy or borrow a local equivalent.
- Charger says 100–240V: plug adapter only.
- Appliance says 110–120V only: you need a voltage converter, or leave it home.
- Already on round-pin European plugs: you likely need nothing.
What to actually pack
Bring at least one universal travel adapter with round European pins, and ideally a small power strip or multi-port USB charger so a single adapter can power several devices at once — handy when you are travelling as a couple or a family with a pile of phones, watches, and cameras to recharge each night. A compact USB-C charger with multiple ports is the single most useful gadget for modern travellers.
Power reliability and surge protection
Mains power in Bali is generally reliable in the main tourist areas, but brief outages and occasional voltage fluctuations do happen, especially during heavy rain in the wet season or in more remote parts of the island. Larger hotels and villas often run backup generators. If you travel with expensive or sensitive equipment, a small surge protector adds cheap peace of mind.
Buying adapters locally
If you do forget, do not panic — adapters are widely sold in Bali at minimarkets, electronics shops, and even some convenience stores near tourist hubs, though selection and quality vary and prices in tourist zones run higher than at home. It is still cheaper and far less stressful to pack the right adapter before you leave.
In short: pack a round-pin European plug adapter, check that your chargers read 100–240V, and leave single-voltage heat appliances at home. Sort that out and every device you own will charge happily under the Balinese sun.
