Plugging your phone charger into a hotel room in Bali and noticing that the wall socket looks exactly like the one in your living room in France is the pleasant surprise that awaits most travelers. However, a few technical details should be checked before departure to avoid an evening without battery or, worse, a damaged device.
The hidden switch on wall sockets in Bali
You just plugged in your charger, but the LED doesn’t light up. Before thinking there’s an electrical problem, take a closer look at the socket. In many recent accommodations in Bali (hotels, villas, guesthouses), each wall socket has a small integrated switch that cuts off the power.

This button, often red or white, is off by default. Simply flip it to “ON” for the power to come through. French-speaking travel guides rarely mention this detail, even though it is the primary cause of unnecessary panic upon arrival.
Some accommodations also use a centralized wall switch that controls a group of sockets. If nothing is working in the room, look for a switch near the door before calling the reception. To better understand the electrical sockets in Bali, this simple reflex resolves most situations.

Type C, type F: which electrical socket is used in Bali
Indonesia uses type C sockets (two round pins), identical to those found in France, Belgium, or Germany. Specifically, if your charger has two round pins, it fits directly into the socket without an adapter.
Type F (with side grounding contacts) also exists in some buildings. A standard French type E plug (with the protruding grounding pin) may pose a problem: this pin does not have a corresponding hole in a type C socket. In practice, most phone, laptop, and camera chargers use flat type C plugs without a grounding pin. They connect without difficulty.
The case of devices with grounding plugs
A French hairdryer or straightener equipped with a type E plug (protruding grounding pin) will not fit into a standard type C socket. This is the only case where an adapter becomes necessary for European travelers. A C/F to E adapter costs a few euros and is easily found before departure.
Voltage and frequency in Bali: check the compatibility of your devices
International databases now list Indonesia as 230 V / 50 Hz, in line with harmonization with the IEC standard. Many blogs still mention 220 V out of habit, but the difference is negligible for your devices.
Why is this good news? The French network also operates at 230 V / 50 Hz. Your European devices are therefore compatible without a voltage converter.
Read the label on your charger before leaving
Turn over your charger or power supply. You will find a mention like “Input: 100-240V ~ 50/60Hz”. If this range is indicated, the device accepts current from almost all countries in the world, including Bali. No need for a converter.
The devices that pose a problem are those designed for a single voltage (for example, “120V” for a device purchased in the United States). In this case, a voltage converter is mandatory, or you risk burning out the motor or internal circuit.
- Phone, tablet, laptop chargers: almost all are multi-voltage (100-240V), directly compatible
- Resistance devices (hairdryers, irons, travel kettles): often single-voltage, must be checked on the label
- Electric razors and toothbrushes: generally multi-voltage, but the mention varies by brand
Universal adapter or USB power strip: what to pack in your suitcase
Since standard European plugs work directly in Bali, a classic adapter is only useful if you are traveling with devices that have grounding plugs or if you are visiting multiple countries (Thailand, Vietnam, Australia) where the formats differ.
A universal adapter with built-in USB ports remains the most versatile choice for a multi-destination trip. It replaces several adapters and allows you to charge your phone and tablet simultaneously without monopolizing the wall sockets.
- For Bali only with standard European devices: no adapter needed in most cases
- For a Southeast Asia circuit (Thailand, Vietnam, Indonesia): a universal adapter covers all formats encountered
- To charge multiple devices at the same time: a small travel power strip with USB ports avoids searching for free sockets in the room
- A voltage converter is only useful for single-voltage devices, which excludes almost all modern electronics
Power outages and electrical network instability in Bali
The Balinese electrical network experiences micro-outages, especially outside the main tourist areas and during the rainy season. Neighboring islands (Nusa Penida, Gili) are even more exposed to these interruptions.
Mid-range and higher hotels generally have backup generators that kick in within seconds. In guesthouses or more modest villa rentals, an outage can last from a few minutes to several hours.
Protecting sensitive devices
Voltage fluctuations related to outages and power restorations can damage a laptop or external hard drive. A power strip with surge protection weighs little in a suitcase and protects your equipment. It’s an investment of a few euros that can save irreplaceable photo files.
If you work remotely from Bali, a good capacity external battery complements this protection well. It allows you to continue using your phone and tablet during outages without relying on the electrical network.
The electrical compatibility between France and Bali is one of the simplest in Southeast Asia. Check the label on your resistance devices, locate the switches on the wall sockets, and slip a small surge protector power strip into your luggage. The rest plugs in directly.
