India Power Plugs, Wall Sockets & Electrical Outlets
In India, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded), Type D (BS 546, three large round pins in triangular pattern, grounded) and Type M (BS 546 (15A), three large round pins in triangular pattern, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to India.

Do You Need a Travel Adaptor for India?
If you're travelling to India from a country that doesn't use Type C, Type D, or Type M plugs, you will need a travel adaptor. The India power plug landscape is dominated by three-pin, round-pin designs that differ significantly from the flat-pin plugs used in the UK, US, Australia, and many other regions. Packing a universal adaptor with round-pin configurations will cover most hotels, homes, and public charging points across the country.
Voltage and Frequency in India
India runs on a 230V supply at 50Hz, which is standard across most of Asia, Europe, and Africa. Travellers from countries using 220-240V systems typically don't need a voltage converter, since their devices are already designed for this range. However, visitors from 110-120V countries, such as the United States or Canada, should check whether their appliances are dual-voltage before plugging in, as a mismatch could damage single-voltage equipment.
Plug Sockets, Voltage & Adapters in India
India primarily uses Type D and Type M plugs, both grounded three-pin designs descended from the old British BS 546 standard, alongside the ungrounded two-pin Type C Europlug for smaller electronics. A standard 3-pin plug top in India will typically have three large round pins arranged in a triangular pattern, with the top pin serving as the grounding pin and the lower two carrying live and neutral current.
Do All Sockets in India Look the Same?
Not quite. Type D and Type M sockets look similar at a glance but are not interchangeable, because Type M pins are noticeably larger and built to handle far greater current. Type D is the everyday grounded plug used for household appliances, computers, and general electronics rated at 5 amps, while Type M is reserved for higher-power equipment like air conditioners and geysers rated up to 15 amps. Meanwhile, Type C Europlugs are common for compact chargers and small devices, though they fit loosely in some outlets and lack grounding entirely.
- Type C (Europlug): two round 4mm pins, ungrounded, rated 2.5A, suited to low-power electronics like phone and laptop chargers.
- Type D (BS 546): three round pins in a triangular layout with a larger grounding pin, rated 5A, the standard grounded plug for most Indian households.
- Type M (BS 546 15A): a heavier-duty version of Type D with larger pins, rated 15A, used for high-consumption appliances such as air conditioners and ovens.
Frequently Asked Questions
Yes, unless your home country already uses Type C, Type D, or Type M plugs. Most international visitors will need an adaptor with round pins to fit India's grounded three-pin sockets, especially for higher-power appliances that require Type M outlets.
In most cases, yes. India's 230V, 50Hz supply matches what phone chargers are designed to handle, since they're typically rated for 220-240V input. You'll still need a physical plug adaptor to fit the Type C, D, or M sockets, but a voltage converter usually isn't necessary for phone charging.
Most are. Type D and Type M sockets, which are the dominant plug types in India, are both grounded three-pin designs featuring a dedicated grounding pin. The exception is Type C, an ungrounded two-pin plug used mainly for small Class II devices that don't require grounding.
India operates on 230V at a frequency of 50Hz. This is consistent with the electrical standards used across much of Europe, Asia, and Africa.
