Plugs & Electricity

Sri Lanka uses three plug and socket types, which can vary depending on the age and type of building you are staying in. Understanding each type will help you choose the right adapter before your trip.

Type D (Old Indian Standard): This is a round three-pin plug with three large round pins arranged in a triangular pattern. The pins are 7mm in diameter, spaced 19mm apart. Type D was inherited from British colonial standards and remains common in older buildings, budget guesthouses, and rural areas across the island. It is the same plug used in India, Nepal, and parts of Africa. If you are travelling between Sri Lanka and India, the same adapter will work for both countries.

Type M (Large Three-Pin Round): Type M looks similar to Type D but is larger, with pins that are 8.7mm in diameter. It was originally designed for appliances drawing higher current, such as air conditioners, water heaters, and kitchen equipment. You will sometimes find Type M sockets in hotel rooms alongside Type D or Type G sockets, particularly in mid-range and older accommodation. Some newer buildings use Type M as the standard wall socket.

Type G (UK-Style): The rectangular three-pin plug used in the United Kingdom, Ireland, Malaysia, Singapore, and several other former British territories. Type G sockets are increasingly common in Sri Lanka, especially in modern hotels, resorts, and newly built guesthouses. Many upscale properties in Colombo, Galle, and popular tourist areas have fully switched to Type G sockets. If you are travelling from the UK, you may not need an adapter at all in some hotels.

Multi-Type Sockets: Many modern Sri Lankan hotels and guesthouses have installed multi-type or universal wall sockets that accept Type D, Type M, Type G, and sometimes Type C (European two-pin) plugs. These sockets are designed specifically to accommodate international guests and are becoming increasingly common in tourist-facing accommodation. Always check with your hotel in advance if you want to confirm which socket types are available in your room.

Sri Lanka's electrical supply operates at 230 volts and 50 hertz. This is the same standard used across most of Europe (including the UK, France, Germany, and Spain), Australia, most of Asia, and Africa. If you are travelling from any of these regions, your devices will work without any voltage issues.

Travellers from North America, Japan, and parts of Central America need to pay special attention, as these countries use a 110-120V supply. Plugging a device designed only for 110V into a 230V socket without a converter will damage or destroy the device, and could cause a fire or electric shock. Always check the label on your charger or appliance before plugging it in.

Good news for most travellers: The vast majority of modern electronics are designed with dual-voltage or multi-voltage capability. Check the small print on your laptop charger, phone charger, tablet charger, or camera battery charger. If it says "Input: 100-240V, 50/60Hz" you are safe to use it anywhere in the world with just a plug adapter and no voltage converter. Most Apple, Samsung, Dell, HP, and other major brand chargers are multi-voltage.

Devices that may need a voltage converter: Appliances with heating elements or motors, such as hair dryers, hair straighteners, curling irons, electric razors (older models), and some travel kettles, are often single-voltage. If your device is rated only for 110V, you will need a step-down voltage converter. However, a simpler option is to buy a cheap dual-voltage travel hair dryer before your trip, or simply use the one provided by your hotel. Most mid-range and upscale hotels in Sri Lanka provide hair dryers in the room.

Whether you need an adapter depends on where you are travelling from and what plug type your devices use. Here is a quick breakdown by region:

From the UK, Ireland, Malaysia, Singapore, Hong Kong: You use Type G plugs, which are widely supported in Sri Lanka, especially in modern hotels. You may not need an adapter at all, but it is wise to carry one as a backup in case your accommodation uses older Type D or Type M sockets.

From India, Nepal, Pakistan, Bangladesh: You use Type D plugs, which are natively compatible with the many Type D sockets found across Sri Lanka, particularly in older buildings and budget accommodation. You should still carry an adapter for Type G sockets, which are common in newer hotels.

From Europe (Type C / Type E / Type F): European two-pin plugs (Type C) will sometimes fit into multi-type sockets but are not guaranteed to work in standard Sri Lankan sockets. You will need a Type C to Type G or Type C to Type D adapter. A universal adapter is the safest option.

From the USA, Canada, Mexico, Japan (Type A / Type B): North American flat-pin plugs are not compatible with any Sri Lankan socket. You will definitely need an adapter. Additionally, check whether your devices are dual-voltage (100-240V). If they are single-voltage (110-120V only), you will also need a voltage converter for any appliances with heating elements or motors.

From Australia, New Zealand, China (Type I): Australian and Chinese plugs are not compatible with Sri Lankan sockets. You will need a Type I to Type G or a universal adapter.

When in doubt, a universal travel adapter is always the safest and most versatile choice. It covers you for Sri Lanka and any other countries on your itinerary.

A universal travel adapter is the single most useful electrical accessory you can pack for Sri Lanka. Rather than buying a country-specific adapter, a universal adapter works in over 150 countries and will serve you on future trips as well. Here is what to look for when choosing one:

Key features to look for:

• Multiple plug configurations: Ensure the adapter supports Type A, Type B, Type C, Type G, Type I, and ideally Type D and Type M inputs and outputs.
• Built-in USB ports: Modern universal adapters come with 2-4 USB-A ports and often a USB-C port, allowing you to charge multiple devices simultaneously without carrying separate chargers.
• USB-C Power Delivery (PD): If you need to charge a laptop via USB-C, look for an adapter with USB-C PD support (at least 30W, ideally 65W for faster laptop charging).
• Surge protection: A built-in surge protector safeguards your expensive electronics from voltage spikes, which can occur in Sri Lanka, particularly in rural areas or during storms.
• Compact and lightweight: You will be carrying this in your daypack, so choose one that is small enough to travel comfortably.

Important note: A travel adapter only changes the plug shape. It does not convert voltage. If you have a 110V-only device, you need a separate voltage converter in addition to the adapter. Most modern chargers for phones, laptops, and cameras are dual-voltage (100-240V) and only need an adapter.

You can purchase universal adapters at electronic shops in Colombo, including at Bandaranaike International Airport arrivals, but the selection and quality will be better if you buy one before your trip. Prices at the airport tend to be inflated.

Sri Lanka has experienced power supply challenges in recent years, though the situation has improved significantly since the acute energy crisis of 2022. The country generates electricity from a mix of hydropower, thermal (coal and oil), and a growing share of renewable sources including solar and wind. During dry seasons, when hydropower generation drops, the grid can come under strain.

Scheduled power cuts (load shedding): During periods of high demand or low generation capacity, the Ceylon Electricity Board (CEB) may implement scheduled power cuts in certain areas. These are typically announced in advance through local media and usually last 1-3 hours. Tourist areas and major hotels are often on priority circuits and experience fewer disruptions. As of 2025-2026, scheduled power cuts have become much less frequent than during the 2022 crisis, and most tourists will not experience them.

Unscheduled outages: Brief power interruptions can occur anywhere, particularly during heavy monsoon rains and thunderstorms. These are usually resolved within minutes to a few hours. Rural areas and smaller towns may experience outages more frequently than cities.

Hotel generators: Most mid-range and upscale hotels, resorts, and larger guesthouses have backup diesel generators that kick in automatically during a power outage. If uninterrupted power is important to you (for example, if you are working remotely), confirm with your accommodation that they have generator backup before booking.

What to do during an outage: Keep a small torch or headlamp in your daypack. Charge your phone and power bank whenever you have the opportunity so you are not caught with a dead battery. If you are using a CPAP machine or other medical device that requires continuous power, bring a portable battery backup and inform your hotel in advance so they can prioritise your room's power supply.

Keeping your devices charged while travelling around Sri Lanka is straightforward with a little planning. Here are practical tips for staying powered up throughout your trip:

Carry a power bank: A portable power bank (10,000-20,000 mAh) is essential for long travel days. The scenic train journey from Kandy to Ella takes 6-7 hours, and while some newer carriages have power outlets, most do not. Long bus journeys, safari drives, and full-day excursions to sites like Sigiriya or Anuradhapura also mean extended periods away from a power source.

USB charging opportunities: Many cafes, restaurants, and co-working spaces in tourist areas offer USB charging points or accessible wall sockets. It is polite to ask before plugging in. Some modern tuk-tuks and private hire vehicles also have USB charging ports.

Protect your devices: Use a surge protector, especially in budget accommodation or rural areas where the power supply may be less stable. Voltage spikes can damage sensitive electronics like laptops and camera equipment. A small power strip with built-in surge protection also gives you extra outlets if your room only has one or two sockets.

Camera batteries: If you are a keen photographer, bring at least two camera batteries and charge one while using the other. Wildlife safaris in Yala or Udawalawe and long hikes to places like Horton Plains will drain batteries quickly, especially if you are shooting video.

Drone batteries: If you are flying a drone in Sri Lanka (permits required), bring multiple batteries and a multi-charger. Drone batteries take longer to charge and you will want to be ready for each day's flying opportunities.

Solar chargers: For off-the-grid adventures or extended trekking, a portable solar panel charger can be useful. Sri Lanka receives strong sunlight year-round, making solar charging viable even during the monsoon season on dry days.
