Voltage and socket type
- Voltage: 220 V, 50 Hz frequency, as in France.
- Socket types: A and B (two or three flat pins), C (two round pins, the European "Europlug"), sometimes O, the official Thai type. Many recent sockets are "universal" and accept several shapes.
- Three-hole (earthed) sockets are common in recent hotels and shopping centres.
Which adapter to pack?
- From France and Europe: a type C plug (two round 4 mm pins) fits most universal sockets; earthed E/F plugs do not always go in. A universal travel adapter is the safest.
- From the United States, Canada or Japan (flat plugs, 100–120 V): flat plugs fit, but the voltage is different, see below.
- From the United Kingdom or Australia: an adapter is needed.
Do your devices handle 220 V?
Look at the charger label: if it says "INPUT 100–240 V, 50/60 Hz", the device works anywhere with a simple plug adapter. That is the case for most phone, laptop, camera and tablet chargers. A hairdryer, iron or shaver made for 110 V, however, can be damaged at 220 V: use a voltage converter only if essential, or buy the device locally.
In hotels, rentals and coworking spaces
Hotels sometimes lend adapters; ask at reception. In rented accommodation, check there are sockets near the bed. Bring a travel power strip with surge protection if you plug in several devices: voltage variations happen.
Buying locally
Adapters are sold in shopping centres, in the electronics shops of malls, in supermarkets and airport shops, at very varied prices: do not wait for the airport if you can avoid it. It is better to buy one before leaving.
Power banks and flying
Power banks go in the cabin, never in the hold. Check your airline's rules. For other rules of the stay, see our guide to the first trip to Bangkok and visa and entry to Thailand.
