What plug type is used in Singapore?
See and understand Singapore's plug shape and socket design.

Singapore uses the Type G power plug, with three rectangular pins arranged in a triangular pattern. The plug follows the British BS 1363 standard and is also used in Malaysia, the UK, and Hong Kong. Its distinctive three-pin design provides a secure connection and grounding for added electrical safety.
Travellers from countries that use Type A, B, C, E, F, or I plugs will generally need a plug adapter to use Singapore’s sockets. However, travellers from Malaysia, the UK, or Hong Kong can usually use their Type G plugs without an adapter. Planning your Singapore trip? Make sure you have the right adapter and check your devices’ voltage requirements before you go. Check our Singapore travel guide for everything you need before arrival.
What is the voltage in Singapore?

Singapore uses a 230V electrical supply at 50Hz. This is the standard single-phase supply specified under Singapore’s electricity regulations.
Whether your device is compatible depends on its voltage rating. Check the small label on your charger or appliance for an “Input” or “Voltage” specification.
How to Check Device Compatibility
Look for one of these markings:
| Device Label | Compatible in Singapore? | What You Need |
|---|---|---|
| 100–240V, 50/60Hz | ✅ Yes | Plug adapter if needed |
| 220–240V, 50Hz | ✅ Yes | Plug adapter if needed |
| 110–120V only | ❌ No | Voltage converter/transformer required |
| 100V only | ❌ No | Voltage converter/transformer required |
Most modern phones, laptops, tablets and camera chargers are dual-voltage and commonly support 100–240V, so they generally only require a plug adapter when the plug shape is different.
Important: A plug adapter only changes the plug shape. It does not convert voltage. If your appliance is not designed for Singapore's 230V supply, do not plug it in without the appropriate voltage converter.
Do you need a travel adapter for Singapore?
Clarify if you need an adapter or converter based on where you're coming from and your devices.
It depends on the plug type used in your home country. Singapore mainly uses Type G plugs, with three rectangular pins arranged in a triangular pattern.
🇲🇾 Malaysia: No adapter usually needed — Type G is also commonly used. 🇬🇧 UK: No adapter needed. 🇭🇰 Hong Kong: No adapter needed. 🇺🇸 US/Canada: Yes, you’ll need a Type G adapter. 🇯🇵 Japan: Yes, you’ll need a Type G adapter. 🇦🇺 Australia/New Zealand: Yes, you’ll need a Type G adapter. 🇪🇺 Most European countries: Yes, you’ll generally need a Type G adapter.
Important: A travel adapter only changes the plug shape. It does not convert voltage. Singapore uses 230V, 50Hz, so also check your device’s voltage rating before plugging it in.
Plug adapter vs voltage converter: what's the difference?
Clear up confusion: when you need just an adapter, and when to pack a converter.
A plug adapter changes the shape of your plug so it fits Singapore’s Type G outlets; the voltage and frequency stay the same. A voltage converter, on the other hand, changes the electrical supply itself, such as reducing Singapore’s 230V supply to 110V for single-voltage electronics.
Imagine you’ve brought a US laptop: the power brick usually says “100–240V”—in this case, a Type G plug adapter is all you need. But if you bring a US curling iron labelled “110V only,” you’ll need both a plug adapter and a suitable voltage converter. Using only an adapter with a single-voltage device can damage the appliance and may create a safety hazard.
In general, plug adapters are lightweight and simple, making them ideal for phones, laptops, and other dual-voltage electronics. Voltage converters are bulkier and are mainly needed for specialised 110V-only appliances, such as some hairdryers, curling irons, or straighteners. Always check your device’s voltage label before travelling to Singapore.
How to Choose the Right Travel Adapter for Singapore
Pick the best adapter for your trip scenario—solo, group, or digital nomad.
Match Your Travel Style
-
Solo or Short Trip: A dedicated Type G (BS 1363) adapter is compact and reliable. Look for a properly grounded three-pin design rather than a two-pin option. Ideal for light packers and short holidays in Singapore.
-
Digital Nomad or Gadget Lover: Choose a multi-port adapter with USB-A and USB-C connections. If fast charging is important, check the USB-C output—18W or higher can be useful for compatible devices. Some premium models also offer surge protection and replaceable fuses.
-
Family/Group: Consider a quality travel power strip rated for Singapore’s 230V supply or a universal adapter with multiple outputs. Check the total wattage rating to ensure it can safely support all your connected devices.
-
Multi-Stop Regional Adventure: A universal travel adapter is the most versatile option. Make sure it supports Type G plugs and provides proper grounding, as lower-quality models may not offer the same level of electrical protection.
Before buying, check the adapter’s plug compatibility, voltage rating, wattage capacity and safety certification. Choosing a reliable adapter can help keep your devices powered and your trip to Singapore hassle-free.
Pre-departure checklist and FAQs
Easy-to-read checklist and answers to the most common adapter questions for Singapore.
- Count Adapters: Bring a Type G adapter per device, or use a power strip/multi-port charger rated for 240V to simplify charging.
- Verify Hair/Medical Tools: Carefully check voltage compatibility on hairdryers, straighteners, and medical equipment—these are often single-voltage and could be damaged.
- Backup Plan: Bring a spare Type G adapter as a backup in case one is lost or fails.
- Don't Rely on Hotels: Even if accommodation claims to offer adapters or universal sockets, bring your own to avoid running into shortages during peak periods.
* Hotels: Many hotels provide power outlets or USB charging points in guest rooms.
* Cafés: Some cafés offer free access to power outlets for customers.
* Shopping malls: Look for charging stations in common seating area
Final takeaway for a stress-free Singapore trip
Your condensed strategy—for staying charged and problem-free in Singapore.
Staying powered up in Singapore is easy when you prepare before you go. Singapore uses Type G plugs, 230V and 50Hz, so check your devices and pack the right adapter for your trip.
For most phones, laptops and other modern electronics labelled 100–240V, a Type G travel adapter is all you need. If you’re bringing a 110V-only appliance, check whether you also need a suitable voltage converter.
Pack your adapter, charging cables and a power bank, and you’ll be ready to explore Singapore without worrying about running out of battery.
