The fan is on a two-pin round one, the kettle is on a three-pin, and the socket by the bed that would be the only convenient one for a laptop is occupied by a lamp you cannot unplug. This is a normal Thai hotel room and the fix is a five-baht adapter bought from a shop that is now closed. Last verified 5 September 2026. ## What Thailand actually runs **220 volts, 50 hertz.** That is European voltage, so if your device is 220 to 240V you are fine everywhere in the world and need no converter at all. **Most modern chargers and laptops handle 100 to 240V automatically,** and the vast majority of things people carry now do. A hairdryer is the classic exception: hairdryers are almost always single-voltage and the small printed voltage on the underside is not a suggestion. **So the question is not "will this voltage work", it is "does this device need a converter",** and for anything with a power supply brick the answer is almost always no. ## Which plug shapes work **Type A, two flat parallel pins, is the US and Japanese shape and it works.** This is the most convenient thing about Thailand for anyone who has US or Japanese equipment. **Type C, the round two-pin Euro plug, works.** This is the standard across most of continental Europe and it fits Thai sockets too. **Type O, the round three-pin Indian plug, also appears.** It fits in some Thai sockets. **Type G, the UK three-pin rectangular plug, does not work** and this catches British and Irish travellers more than anyone else, because they assume every country has the same sockets as home. **Type D, the Indian three-pin, does not work.** ## What to actually buy **A universal travel adapter, and only one.** They are sold everywhere including [7-Eleven](https://easythailandvisa.com/thailand-7-eleven-convenience-store/), they cost 100 to 300 baht, and a multi-plug adapter with USB ports is genuinely more useful than three separate things. **Buy a multi-port USB charger rather than a multi-plug adapter.** This is the advice that has become true in the last five years: almost everything you carry charges over USB, and a single mains charger with two or three USB ports replaces a bag of adapters entirely. **Buy it before you need it.** The first shop that sells adapters is usually open, but it will not be open at midnight, at an airport at 1am, or anywhere on a Sunday in a small town. This is a "buy in the first hour" item. ## Grounding, which is the one people get hurt by **Many Thai sockets, particularly older ones, are two-pin ungrounded.** A grounded three-pin plug will usually fit, usually with a bit of force or an earth-pin lifter, and the ground connection may go nowhere. **Do not use a cheap adaptor that does not carry earth through,** particularly for anything with a heating element or a motor: a hair dryer, an iron, a kettle, a fan, a vacuum. These are exactly the appliances where a missing earth matters, and the cost of an adapter that carries it is a small fraction of the cost of a different piece of plastic. **And if a plug gets hot, smells, or needs unusual force, stop using it.** A hot or discoloured socket in a tropical climate is a bad sign and it is worth reporting to reception rather than working around. ## Power cuts and what to do about them **Brief outages happen, more in the provinces and more in the wet season,** and they are usually short. The Thai grid is not as reliable as Singapore's and is considerably more reliable than parts of the Philippines or Nepal. **Carry a charged power bank, not a spare battery,** because a power bank is also your answer to the airport queue, the long night bus and the day you are lost. **Never leave a fridge open thinking it will stay cold through a cut,** which is a thing everyone tries once. **And in a homestay or a long-term rental, ask what happens during an outage,** because in a building with a backup generator the difference between a two-minute flicker and three hours in the dark is entirely down to whether the place has one. ## The thing that is not a problem **Voltage is a solved issue for essentially all modern equipment and you do not need a converter.** The whole problem reduces to a five-baht piece of plastic, and the real risk is the one where somebody brings a single-voltage hairdryer to a 220V country and does not check the label. Read the label on anything with a motor or a heating element. Everything else you are carrying is fine. **More on this** - [What Happens If Your Arrival Card Does Not Match Your Passport](https://easythailandvisa.com/arrival-card-mismatch-immigration/) - [Your Bank Called to Say the Card in Thailand Was Captured,](https://easythailandvisa.com/atm-and-card-fraud-in-thailand/) - [March in Bangkok Is Not a Travel Month and the Air Quality](https://easythailandvisa.com/bangkok-air-pollution-when-not-to-come/)
