Singapore Plug Type and Voltage: Do You Need an Adapter?
Plugs in United States
120 V · 60 Hz
Sockets in Singapore
230 V · 50 Hz
Singapore sockets take the three-pin Type G plug (13 A, rectangular pins, standard SS 145). Large round-pin Type M sockets (15 A, SS 472) are mostly for air conditioners and water heaters. Never force a two-pin plug into a Type G socket by pushing open the shutters.

Adapter needed
- Plug adapter
- A → Type G
- Voltage
- 120 V → 230 V
- Voltage converter
- Not for 100–240 V chargers
- Frequency
- 60 Hz vs 50 Hz
Chargers do not mind 50 or 60 Hz. Motors and analogue clocks built for one frequency can run slower or faster on the other.

Single-phase household voltage. Plug letters follow the IEC system; the main type is listed first.
How this works
Singapore's mains supply is 230 V at 50 Hz, and standard sockets take the Type G plug: three rectangular pins, 13 A, made to Singapore Standard SS 145 (the same layout as the UK's BS 1363). A few high-power appliances such as air conditioners and water heaters use the larger round-pin Type M (15 A, SS 472). Plugs sold in Singapore are controlled goods that must carry the Safety Mark under Enterprise Singapore's Consumer Product Safety Office.
An adapter only changes the shape of the plug. You need one whenever your plug is not Type G. A voltage converter changes the voltage, and you only need one for a single-voltage appliance moving between a 100 to 127 V country (the US, Canada, Japan, Taiwan, Mexico) and a 220 to 240 V country like Singapore. Most phone, laptop and camera chargers say "Input 100–240V, 50/60Hz" and need only an adapter.
Plug letters (A to O) follow the system from the IEC's World Plugs guide, which the IEC retired in 2026. Country plug types, household voltages and frequencies in the table come from the compiled list on Wikipedia's Mains electricity by country (checked 10 October 2026), which cites national standards bodies and utilities. Where a country uses several types, the main one is listed first.
FAQs
What plug type does Singapore use?
Type G, the three-pin plug with rectangular pins, rated 13 A, the same as in the UK, Ireland, Hong Kong and Malaysia. Some air conditioners and water heaters use the larger round-pin Type M.
What is the voltage in Singapore?
230 V at 50 Hz. Devices labelled 100–240V work without a converter; appliances made only for 110 V or 120 V (common in the US, Canada, Japan and Taiwan) need a step-down converter or they can be damaged.
Do I need a plug adapter in Singapore from the US?
Yes. US plugs are Type A or B, so you need a Type A/B to Type G adapter. US phone and laptop chargers are usually 100–240V and work with just the adapter; a 120 V-only hair dryer needs a converter as well.
Do I need an adapter in Singapore from the UK or Malaysia?
No. The UK, Ireland, Hong Kong and Malaysia also use Type G plugs at 220 to 240 V, so British and Malaysian plugs fit Singapore sockets directly.
Can I use a Singapore hair dryer in Japan?
Not well. Japan is 100 V, so a 230 V-only Singapore hair dryer runs weakly or not at all, and you need both a Type G to Type A adapter and a step-up converter. A dual-voltage travel dryer is the simpler option.
