India Plug Type: Sockets, Voltage and Adapters
The India plug type you need is Type D, with Type M sockets turning up on higher-power appliances. The supply is 230V at 50Hz, which is the same as the UK, so British visitors need a plug adapter but not a voltage converter.
That distinction trips people up constantly, so it is worth separating early: an adapter changes the shape of your plug, a converter changes the voltage. Travelling from the UK to India you need the first and not the second. Travelling from the US you may need both, depending on what you are carrying.
Quick Answer
- Official plug types: D and M
- Also fits: Type C (the two-round-pin Europlug) goes into most Type D sockets
- Voltage: 230V
- Frequency: 50Hz
- UK travellers: Adapter yes, converter no
- US travellers: Adapter yes, converter only for 120V-only devices
The Standard Voltage and Frequency in India
India operates on a standard supply voltage of 230V with a frequency of 50Hz. This is the same as Europe, Australia, and the United Kingdom, but differs significantly from the 110-120V and 60Hz system used in the United States, Canada, and some South American countries.
The Indian Standard IS12360 specifies an acceptable voltage range for single-phase supply between 207V and 253V. This acknowledges that the real-world supply can fluctuate slightly. Most modern electronics handle this without issue, but it’s worth knowing.
What Plug Type Does India Use?
India’s official standards are Type D and Type M. You will also encounter Type C constantly, which is where most of the confusion comes from.
| Type | Pins | Rating | Where you meet it |
|---|---|---|---|
| Type D | 3 round, triangular | 6A | The standard socket in hotels and homes |
| Type M | 3 round, triangular, larger pins | 16A | Air conditioning, fridges, washing machines |
| Type C | 2 round, parallel | 2.5A | Not official, but physically fits most Type D sockets |
Type D is the one that matters for travellers. Three round pins in a triangle, and it is what your hotel room socket will almost certainly be. It is also used in Sri Lanka, Nepal and parts of Africa.
Type M looks like a scaled-up Type D. The two are not interchangeable: a Type M plug will not fit a Type D socket, though it is used for fixed high-power appliances rather than anything you would plug a charger into.
Type C, the two-round-pin Europlug, is not one of India’s official standards, but the pins are close enough to Type D that it slots into most Indian sockets. This is why some guides list India as “C, D and M” and others list only “D and M”. Both are describing the same reality — one is listing the standard, the other is listing what actually works. In practice a Europlug will usually charge your phone in India; it just is not what the socket was designed for, and it will sit loose.
A universal travel adapter covers all three and is the safest option.
Do You Need a Voltage Converter?
Whether you need a voltage converter depends on your device’s voltage rating. Always check the label on your appliance or power adapter first.
If it says “INPUT: 100-240V,” it’s dual voltage and works safely with India’s 230V supply. You only need a plug adapter. Most modern smartphone chargers, laptops, and cameras fall into this category.
If your device is rated for 230V only (common with UK and European appliances), you also only need a plug adapter — the voltage matches.
You need a voltage converter when your device is rated for a different voltage — for example, a 110-120V US appliance. Plugging a 110V device directly into a 230V outlet can cause it to overheat and may damage or destroy it. A step-down converter reduces the 230V supply to the 110-120V the device requires.
| Appliance voltage rating | Indian supply | What you need |
|---|---|---|
| 100-127V (US single-voltage) | 230V | Step-down voltage converter and plug adapter |
| 220-240V (UK/EU) | 230V | Plug adapter only |
| 100-240V (dual voltage) | 230V | Plug adapter only |
Which India Plug Adapter Do You Need?
Regardless of voltage compatibility, you almost certainly need a plug adapter for India. US plugs (Types A and B) and UK plugs (Type G) do not fit Indian sockets.
Look for one described as “UK to India” or “Type G to Type D”. A universal adapter works too and is worth it if India is one stop of several. Expect roughly £5-12 for a decent one with USB ports, as of September 2026. Buy it before you fly.
Remember that a plug adapter only changes the physical shape. It does nothing to the voltage, so it will not protect a 120V-only device from a 230V socket.
Frequency Considerations
Voltage is the main concern, but frequency can also affect certain appliances. India runs at 50Hz, while the United States uses 60Hz.
A clock designed for 60Hz may run slightly slower on a 50Hz supply. Devices with motors or precise timing — electric shavers, fan heaters — may also be affected. For most modern electronics with power adapters (laptops, phones), the label will confirm support for both 50Hz and 60Hz, which is standard.
Tips for Using Electronics Safely in India
A few practical tips for using electronics safely in India:
- Always check the label on your appliances and power adapters to confirm voltage and frequency compatibility. This is the single most important step.
- Avoid overloading outlets or adapters. Too many devices into one outlet can cause overheating.
- Consider a surge protector if you are concerned about voltage fluctuations. The nominal voltage is 230V but variations can occur.
- Unplug devices when not in use, especially overnight.
- Be especially careful with high-power appliances like hair dryers, curling irons, and travel kettles. If you are unsure about compatibility, use the hotel’s appliance or buy one locally.
- Make sure any plug adapters you use are rated for 230V.
- Some adapters are not suitable for appliances requiring an earth connection. Double-insulated equipment is marked with a symbol indicating it does not need earthing.

Summary
India uses 230V at 50Hz, with Type D and Type M sockets. You will need a plug adapter, because neither UK Type G nor US Type A/B plugs fit. Whether you also need a voltage converter depends on your devices: check the label. If it says 100-240V, the adapter is all you need. Always check before you plug in.
Frequently Asked Questions
What is the voltage in India?
India operates on a standard supply voltage of 230V with a frequency of 50Hz. This is the same voltage used in Europe, Australia, and the United Kingdom, but different from the 110-120V and 60Hz system used in the United States and Canada.
What plug type does India use?
India’s official plug types are Type D and Type M, both with three round pins in a triangle. Type D is the standard socket you will meet in hotels and homes; Type M has larger pins and is used for high-power appliances. Type C, the two-round-pin Europlug, is not an official Indian standard but physically fits most Type D sockets, which is why some guides list it alongside D and M.
Do I need a voltage converter for India?
It depends on your device’s voltage rating. If your device is labeled “100-240V” (dual-voltage), you only need a plug adapter. If your device is designed for 110-120V only (common in US devices), you need a voltage converter to safely use it with India’s 230V supply.
Can I use my UK electronics in India?
Yes, UK electronics work in India with just a plug adapter, as both countries use 230V at 50Hz. You don’t need a voltage converter. However, UK Type G plugs don’t fit Indian sockets, so you’ll need an appropriate plug adapter.
Will my phone charger work in India?
Most modern phone chargers are dual-voltage (100-240V) and will work in India with just a plug adapter. Check the label on your charger to confirm it shows the 100-240V range.
Do US travelers need a voltage converter in India?
US travelers need a voltage converter only for single-voltage devices rated for 110-120V. Most modern electronics like phones, laptops, and cameras are dual-voltage and work with just a plug adapter. Hair dryers and other heat appliances often need converters.
