Electricity power in Bali: voltage, plugs and what to expect

Bali uses a 230-volt, 50-hertz electricity supply, the standard for Indonesia. Two round-pin sockets, Type C and Type F, are the common types in Bali, and many plugs used in mainland Europe fit them. Travellers with other plug shapes should pack a suitable travel adaptor. Check the small print on each device as well as its plug: an adaptor changes the shape of the connection, not the voltage or frequency.

For a short trip, the decision is usually simple. Match the plug, confirm the device accepts Bali’s 230 V, 50 Hz supply, and decide which items must stay charged if power is interrupted. Look for the input range printed on a charger or appliance; a range that includes 230 V and 50 Hz covers Bali’s supply. A single-voltage appliance needs different treatment or should be left at home. Electricity is generally available across Bali, but no supply can be treated as uninterrupted, as the outage of 2 May 2025 showed.

Which plug adaptor to bring to Bali

Type C has two round pins. Type F also has two round pins, with metal earthing clips on the sides of the plug and socket. Both appear across Bali, but a plug that looks close to the socket is not proof that it is secure or suitable. Do not force a plug into a socket or rely on a loose connection to hold it in place.

Choose an adaptor that accepts the exact plug you are bringing and is rated for the device you intend to connect. A compact adaptor for a phone charger is not automatically a good choice for a larger appliance. If you carry several chargers, a multi-port charger with a suitable local plug adaptor can reduce the number of sockets you occupy; check its input marking before packing it.

Travelling with a laptop, camera battery charger, headphones and a phone can make one wall socket feel limiting, particularly when several people share a room. A short, properly rated extension lead lets the devices sit together on a desk. Keep charging equipment away from wet surfaces around a pool or bathroom. A travel adaptor with several outlets still draws power through one socket, so it does not give the room more electrical capacity.

Before departure, list the devices you genuinely use, such as phone, camera, laptop, electric toothbrush, shaver or any medical equipment, and count their plug shapes. Do not assume that one universal adaptor will fit every item. Spare adaptors are useful when one is misplaced between stays, but a collection of adaptors packed without checking the device labels adds bulk without solving a voltage problem.

Check voltage and frequency on each device

Look for “Input”, “Voltage” or a range printed on the charger, appliance label or power brick. A label that includes 230 V within its range and 50 Hz is compatible with Bali’s supply. A device marked only for 110–120 V is not made suitable by a plug adaptor. If the rating is unclear, do not guess: leave that appliance behind or confirm its requirements with its manufacturer before travel.

Small electronic chargers often have a wide input range, which is why a phone can charge with only a plug adaptor. Heating appliances need more care. A hair dryer, straightener or curling tool may be designed for one voltage only, even when its plug can be adapted. If it has a dual-voltage switch, the position should match the appliance instructions. Do not assume a dual-voltage setting is present simply because a travel adaptor is marketed for international use.

Frequency appears less often in travel conversations than voltage, but it matters to equipment designed around the timing of the supply. If an appliance label says 60 Hz only, the 50 Hz supply in Bali may affect whether it works well, particularly for equipment with a motor or clock. A travel adaptor does not convert frequency. For medical devices or powered mobility equipment, use the manufacturer’s compatibility guidance rather than a general travel rule.

A voltage converter is a separate device from a plug adaptor. It changes the voltage for a compatible load, and it must be rated for the appliance’s electrical demand. For a one-off holiday, the practical choice is often a dual-voltage version of the item, equipment already provided by the accommodation where appropriate, or travelling without a non-essential single-voltage appliance.

What Bali power interruptions can affect

An interruption is more than a dark room. If a property’s water pump, internet equipment, cooling or access controls depend on electricity, those services may also stop while power is off. Whether they continue on backup, or recover immediately, depends on the building and its equipment. Ask the accommodation host what remains available during an outage if uninterrupted cooling, internet access or powered medical equipment is essential to your stay.

The largest recent disruption was an island-wide outage on 2 May 2025. Reports linked it to a disruption in the undersea cable system that carries power between Java and Bali, and the utility said it was not related to a cyberattack. Supply returned gradually overnight, and most of the island was reconnected by the following morning. This was a specific system event; it does not establish how often an individual guesthouse, villa or neighbourhood loses power.

The scale of that event matters for planning, because it showed that a disruption can affect the island broadly rather than only one room or street. A traveller should not read a past outage as a forecast for their dates. Instead, avoid relying on a single charged phone as the only way to reach an arrival address, booking details or transport plan. Keep essential information available offline and carry a charged power bank if you depend on your phone for navigation or communication.

If lights go out in your room, first ask the host or reception whether the interruption is limited to the building or is affecting the surrounding area. A room circuit, a building fault and an area outage are different problems, and a guest is rarely best placed to diagnose the property’s electrical system. Do not open a meter cabinet or handle wiring. The person responsible for the property can check its supply and deal with any fault.

Power arrangements also differ between properties. Ask the accommodation how its supply is metered and what happens if power stops. If the outage affects only your room while nearby areas remain lit, tell the host promptly so that the meter or a local circuit can be checked. If the outage is wider, report it to the host rather than repeatedly switching room equipment on and off.

Plan charging around a multi-stop Bali trip

Moving between bases changes where you can charge, not the electrical standard. A night in southern Bali followed by a stay inland or on the north coast still uses the same nominal voltage and plug types. The practical difference is access: a room with one convenient socket, a shared family room and a villa with several rooms each create a different charging routine. Keep the charger, adaptor and power bank together in one pouch so they do not end up in separate bags during a transfer.

On a travel day, charge the phone, navigation device and power bank before leaving a room rather than expecting to find a free socket during a stop. This matters most when the next leg is long, when arrival happens after dark, or when the phone holds your route and accommodation details. A power bank is a reserve for small electronics, not a way to run a laptop or a room appliance. Check its own input rating before relying on it.

For an overnight stop before or after a flight, keep one charging set accessible instead of packing every cable deep inside checked luggage. The Bali airport arrival guide helps with the arrival sequence; this electricity page answers the separate question of how to power the devices you bring. If your first night follows a long flight, a phone with an offline copy of the accommodation address is more useful than a bag full of spare electronics.

Travellers using an eSIM or local SIM rely on the phone for more than calls: it may hold maps, ride-hailing access, translation and account verification. Keep the phone charged before a transfer and save important addresses or confirmation details for offline access. The Bali SIM and eSIM guide covers connectivity choices, and electricity planning supports that choice by keeping the device ready to use.

Questions travellers ask about Bali electricity

Can I use a UK phone charger in Bali?

Usually, if the charger’s label includes 230 V and 50 Hz within its input range. Its plug may still need an adaptor if its shape differs from the local sockets. Read the label rather than relying on the brand or the look of the charger.

Do I need a voltage converter or only an adaptor?

If the appliance label includes 230 V within its input range and 50 Hz, a plug adaptor is generally the only remaining issue. If the appliance is designed only for another voltage, an adaptor alone does not make it suitable. A converter is only appropriate when its rating and the appliance’s requirements match.

Are power cuts common in Bali?

The chance of an interruption at a particular property cannot be inferred from one island-wide event. Bali experienced a major outage on 2 May 2025, and supply largely returned overnight. That event is useful context, but it does not predict the conditions during your visit.

What should I do if the power goes out where I am staying?

Contact the host or reception and ask whether the outage is confined to the property or is affecting the area. Let the person responsible for the building check the meter and electrical installation. Keep your phone and power bank available, and do not handle wiring or electrical cabinets.

Does an adaptor make every appliance safe to use?

No. It only provides a physical connection between plug shapes. The appliance still needs to accept the local voltage and frequency, and the adaptor must suit the plug and the electrical load. Check those details before connecting heating appliances or other high-demand equipment.

Make electricity part of your packing check

Pack one adaptor for each plug shape you need, verify the input marking on chargers and appliances, and leave single-voltage equipment out unless you have a suitable solution. A power bank and offline copies of key trip details cover the practical gap if a room or wider area temporarily loses supply. For a broader preparation list, use the Bali packing list.
