Bottom line: Bali’s voltage is 220V, and the sockets are European two-round-pin (Type C/F)—Taiwanese appliances need an adapter (available at local supermarkets for about NT$30-40, roughly USD$1), and be sure to check that your phone/camera/laptop chargers support 220V (most 3C products are compatible, but high-wattage devices like hair dryers and curling irons require special attention to voltage range).
Indonesia and Bali’s standard voltage is 220 volts (220V)—an important detail for travelers planning to bring electronics. Before deciding which devices to pack, ensure they support the international standard of 220 volts so they can be used normally in Indonesia and Bali.
Beyond voltage, the socket type is also a factor. Indonesia uses the European-style two-round-hole socket. Without the right adapter, many hotel sockets 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 one, but not all do, so it’s best to buy one locally 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 that travelers bring abroad (such as phone and tablet charging heads) mostly support “100V-240V wide voltage.” As long as the input voltage range marked on the charger includes 220V, it can be used directly in Bali without needing an additional transformer. Before you go, check the small print on your charger—if it says “Input: 100-240V,” it’s good to go; if it only says 110V, you’ll need to replace it.
If you’re preparing a multi-outlet extension cord like the one shown above, first make sure it supports the 110~220V range before using it. Second, check the plug type—those bought in Taiwan typically have two flat prongs as shown. You’ll also need an adapter (mentioned at the top) to use it safely across different hotels and villas. Lastly, if your devices support PD or QC fast charging, it’s recommended to choose a corresponding high-power charger to significantly cut down charging time and reduce travel anxiety!
Can This “Square-Pin” Universal Adapter Actually Be Used in Bali?
Recently, a traveler in a community group asked: “Can this universal adapter be used in Bali? I’ve heard online that you absolutely need a fully round plug?” The responses from many netizens sharing their real experiences boiled down to a very consistent takeaway:
✔ It works, but in many cases it’s “not stable enough”
Most travelers said:
- It can plug in
- Most hotels allow normal charging
- 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 “round recessed” design. If your universal adapter:
-
Prongs too short
-
Square body behind the prongs
-
Unit too large and heavy
This often prevents it from seating fully, resulting in poor contact.
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 electronics retailers offer a wide range of 220V multi-outlet extension cords, including those with built-in USB ports, making it easy to find one that suits your needs.
It’s recommended to contact your hotel in advance to check if they provide a hairdryer. If not, or if you need a specific model or brand, consider the solutions mentioned earlier, such as buying a local 220V hairdryer or using a voltage converter.
If you bring your own hairdryer, most purchased in Taiwan only support 110V. In Indonesia and Bali, where the standard voltage is 220V, a 110V hairdryer won’t work properly and could even be damaged due to voltage mismatch.
For this situation, the safest and most convenient solution is to buy a 220V hairdryer locally. This ensures it works properly in Indonesia and Bali while avoiding damage from voltage mismatch.

If you insist on using your own hairdryer or curling iron, you can also consider a voltage converter or adapter. A converter can step down 220V to 110V, but make sure to use one with sufficient wattage (W) and meeting safety standards to avoid damaging your appliances or posing a safety risk.
For travelers heading to Indonesia and Bali, understanding voltage and plug information is crucial. Avoid using cheap, unbranded chargers, as poor-quality products can overheat under 220V, posing a safety risk. Prepare the right adapter and a multi-outlet extension cord to keep your electronics working smoothly, so you can fully enjoy your vacation without worrying about compatibility issues!
