Bottom Line: Bali’s voltage is 220V, and sockets are European two-round-pin (Type C/F)—Taiwanese appliances need an adapter (available at local supermarkets for about NT$30-40, or roughly USD$1), and make sure your phone/camera/laptop chargers support 220V (most 3C devices are compatible, but high-wattage items like hair dryers and curling irons require extra attention to voltage range).
Indonesia and Bali use a standard voltage of 220 volts (220V)—key info for travelers planning to bring electronics. Before packing, ensure your devices support the international 220V standard so they work properly in Indonesia and Bali.
Beyond voltage, plug type is another factor to consider. Indonesia uses the European-style two-round-pin socket. Without the right adapter, many hotel outlets may be unusable.

Do You Need an Adapter?
You can buy adapters at local supermarkets; they’re called ‘Adaptor’ in Indonesian (pronounced: ah-dap-tor). You can also ask your hotel if they provide adapters, but not all do, so it’s best to grab one at a local store to be safe—they’re cheap, around NT$30-40 (about USD$1).
Typically, you’ll need at least one adapter plus a 220V-compatible multi-outlet power strip to ensure all your devices work in Indonesia and Bali. Remember, when choosing a power strip, don’t skimp—opt for a trustworthy brand to safely power all your electronics.
How to Prepare a USB Charger?
Modern USB chargers (like those for phones and tablets) typically support a wide voltage range of 100V-240V. Just check the input voltage on your charger—if it includes 220V, you can use it directly in Bali without a separate transformer. Before you go, look for small text on the charger, such as ‘Input: 100-240V’—that means it’s universal. If it only says 110V, you’ll need a replacement.
If you’re planning to bring a multi-outlet extension cord like the one pictured above, first make sure it supports the 110~220V range. Second, check the plug type: in Taiwan, these cords come with two flat prongs, so you’ll also need an adapter (as mentioned earlier) to use them safely in different hotels or villas. Finally, if your devices support PD or QC fast charging, consider a high-power charger to significantly cut charging time and reduce travel anxiety.
Can This ‘Square-Prong’ Universal Adapter Actually Be Used in Bali?
Recently, a traveler in a group asked: ‘Can this universal adapter be used in Bali? I’ve heard online that you need a fully round plug.’ Many members shared their real experiences, and the consensus is quite clear:
✔ It works, but often ‘isn’t very stable’
Most travelers report:
- It can plug in
- It works for charging in most hotels
- But the plug tends to be loose and wobbly
- If it’s too heavy, it may even fall out
The reason is that Indonesia (including Bali) commonly uses European Type C / Type F sockets, many of which have a ‘recessed round’ design. If your universal adapter:
- Prongs too short
- Square body behind the prongs
- The adapter itself is too big and heavy
This makes it hard to fully insert, resulting in a loose connection.
What many seasoned travelers do: just buy one locally 😆
In this discussion, many netizens mentioned:
“Indonesian convenience stores and supermarkets sell them, and they’re very cheap.”
Small, ultra-light, and actually more stable.
Where to buy a 220V multi-outlet extension cord?
If you’re looking for a 220V multi-outlet extension cord, they can be hard to find in physical stores, but there are plenty of options online. Many e-commerce platforms and online electronics stores offer a wide range of 220V multi-outlet extension cords (including those with USB ports), making it easy to find one that suits your needs.
Can I bring my own hair dryer or curling iron?
Most hotels provide hair dryers for guests, though a few do not.
It’s a good idea to contact your hotel before you go to ask if they provide a hairdryer. If they don’t, or if you prefer using a specific brand or model, you’ll need to consider the options mentioned above, such as buying a local 220V hairdryer or using a voltage converter.
If you bring your own hairdryer, keep in mind that most hairdryers purchased in Taiwan only support 110V. In Indonesia and Bali, the standard voltage is 220V, so a 110V hairdryer won’t work properly and could even be damaged due to the voltage mismatch.
The safest and most convenient solution in this case is to buy a hairdryer that supports 220V locally. This way, you can ensure it works properly in Indonesia and Bali, while avoiding damage from voltage incompatibility.
Other Areas/Villa Accommodation Recommendations
If you really want to use your own hairdryer or curling iron, you can also consider using a voltage converter or adapter. A converter can step down 220V to 110V, but make sure to use one that provides sufficient wattage (W) and meets safety standards to avoid damaging your appliances or creating a safety hazard.
For travelers heading to Indonesia and Bali, understanding these voltage and plug details is essential. Avoid using cheap, unbranded chargers—under 220V, low-quality products can overheat and pose a safety risk. Packing the right adapters and a multi-outlet extension cord will keep your devices running smoothly, so you can fully enjoy your vacation without worrying about compatibility issues.
