If you're planning to travel to Singapore, it's important to know the electrical voltage to ensure your appliances will work safely. Singapore's electrical supply is 220V-240V, or 230V, with a frequency of 50Hz. This is a higher voltage than in some countries, so you may need a voltage converter or transformer for your appliances, as well as a travel adapter. Plugs from the US, Western and Eastern Europe, and most of Asia are not compatible with Singaporean power sockets, which are of the British BS1363 three-pronged square pin type (Type G).

What You'll Learn
Singapore's voltage is 220-240V
Singapore's voltage supply is 220-240V, with a frequency of 50Hz. This is the standard voltage for electrical supply in the country, and it is important to be aware of this when connecting electrical appliances.
The voltage in Singapore is within the 110-240V range that a dual voltage appliance operates on. This means that if you are travelling to Singapore with electrical appliances, you will not need a voltage converter or transformer, just a travel adaptor. However, it is important to check the voltage and frequency of your appliances before connecting them to the power supply in Singapore. If you connect an appliance that is rated at a different voltage, it can be extremely dangerous.
For example, if you are bringing appliances from the US, they will likely use a different voltage and frequency. In this case, you would need to purchase a power converter or transformer to use your appliances safely. You can find power converters and transformers at most HomeFix/SelfFix shops in Singapore.
It is also important to note that Singapore uses the British BS1363 three-pronged square pin type socket, or Type G plug. This is different from the plugs used in the US, Western and Eastern Europe, and most of Asia. As a result, you may need to purchase a travel adapter to use your electrical appliances in Singapore. These are readily available in Singapore and can also be purchased online in advance.

US appliances may need a power converter
The standard voltage in Singapore is 220-240V, 50Hz. If you are bringing a US appliance that runs on a voltage outside of this range, you will need a power converter.
For example, if you have a US appliance that runs on 120V, you will need a step-down transformer to reduce the voltage to the correct level for use in Singapore. It is important to ensure that the power converter has the correct specifications, with an input of 220-240V 50Hz and an output of 110-120V/60Hz.
It is also important to note that Singapore uses the British BS1363 three-pronged square pin type socket. Plugs from the US will not fit into a Singapore power socket, so you will need to purchase a plug adapter or a power converter with the correct plug type.
When using a power converter, it is crucial to get the specifications right. The input and output voltages of the converter must match the requirements of your appliance. Additionally, as frequency (Hz) is difficult to change, it is important to ensure that the converter can output the correct frequency for your appliance.
You can purchase power converters and plug adapters at most HomeFix/SelfFix shops in Singapore, or you can buy them before your arrival to avoid any inconvenience.

The country uses Type G plugs
The electrical voltage in Singapore is 220-240V at 50Hz. If you have equipment that runs on a higher voltage, you should not connect it to a Singaporean power supply without a suitable transformer (voltage adaptor). The country uses Type G plugs, which are similar to those used in the United Kingdom. These plugs have three thick rectangular pins in a triangular pattern. This type of plug is designed with safety features, such as shutters on the sockets, to prevent accidental contact with live parts.
Type G plugs are commonly used in Singapore due to the country's electrical safety regulations. The Energy Market Authority (EMA) oversees these regulations, ensuring that all electrical appliances sold and used in Singapore meet the required safety standards. The Singapore Standard SS 638, based on the British Standard BS 7671, allows for a 6% variation in the supply voltage. This means that the actual voltage can range from 216.2 volts to 243.8 volts.
If you are travelling to Singapore, it is important to note that plugs from other countries, such as the United States, Western and Eastern Europe, and most of Asia, may not be compatible with Singaporean power sockets. You will need to use a travel adapter for these plugs. Universal adapters are a good option to ensure compatibility, and they can be purchased online or at major airports.
Additionally, some appliances may require a voltage converter or transformer if they are not dual voltage rated. A dual voltage rated appliance will typically display something like 'INPUT: 110-240V'. Single voltage rated appliances, on the other hand, will need to operate at the same voltage as Singapore's supply voltage of 230V. It is important to check the appliance's rating plate to determine if a converter or transformer is needed.

The frequency is 50Hz
The electrical voltage in Singapore is 220-240V, with a frequency of 50Hz. This is the standard voltage for electrical supply in the country, and it is important to note that the frequency is different from that of some other countries, such as the US, which operates at 60Hz.
The 50Hz frequency in Singapore is a reference to the alternating current (AC) frequency of the electrical supply. This means that the direction of the current changes periodically, 50 times per second, in an oscillating manner. This is a common standard in many countries and is often used in conjunction with a 220-240V voltage standard.
The 50Hz frequency is an important specification to consider when using electrical appliances in Singapore. It is crucial to ensure that any electrical devices or appliances being used are compatible with this frequency. Devices designed for use in countries with a different frequency may not function properly or may even be damaged if used with the incorrect frequency.
In some cases, devices may be dual voltage rated, which means they can operate within a range of voltages, typically from 110-240V. However, even with dual voltage capability, the frequency compatibility must still be considered. Using a device with an incompatible frequency can affect its normal operation and may even be dangerous.
It is always recommended to check the specifications and ratings of electrical appliances before using them in a different country. If necessary, travellers can purchase voltage converters, transformers, or travel adapters to safely use their devices in Singapore while adhering to the local 50Hz frequency standard.

The voltage is within the 110-240V dual voltage range
The electrical voltage in Singapore is within the 110-240V dual voltage range. The standard voltage in Singapore is 220-240V at 50Hz, which means that a dual voltage appliance can be used in the country without a converter or transformer. However, you will need a travel adapter as Singapore uses the British BS1363 three-pronged square pin type socket, also known as Type G.
If you are travelling to Singapore, it is important to check the voltage and plug type of your appliances to ensure they are compatible with the local electricity supply. A dual voltage rated appliance will typically display something like 'INPUT: 110-240V' on the body of the appliance or its power supply. If you are bringing a single voltage rated appliance, it will need to operate at the same voltage as Singapore's supply voltage, which is 230V.
If your appliance is not compatible with Singapore's electricity supply, you may need to use a voltage converter or transformer. Most voltage converters and transformers come supplied with plug adapters, but it is important to check the maximum power rating to ensure that any appliance you intend to use does not exceed this rating.
It is also worth noting that the frequency of the electricity supply in Singapore is 50Hz, which may be different from other countries. The frequency can affect the normal operation of electrical appliances, so it is important to consider this when bringing electrical devices to Singapore.
