Travel Plug Adaptor for Thailand

There are multiple socket types used in Thailand (A / B / C / G / O). Type O sockets were developed in 2006 and are exclusively used in Thailand. As this is a relatively recent standard and is still being phased in you may be faced with any one of the sockets pictured to the right. There are also some hybrid sockets that can accept type A/B/C/O plugs although these are now being phased out. It may be wise to consider a decent worldwide adaptor that is a single unit capable of connecting to multiple socket types as the type C plugs (unearthed) that these all have are compatible with the new type O sockets. If you have equipment that needs to be earthed then you probably need to consider a dedicated type O plug adaptor as well.

Please be aware that whilst a travel adaptor will allow you to physically plug a UK plug into a different socket it will not change the voltage or frequency of the supply.

Voltage - The mains voltage in Thailand is 220 V which is compatible with all UK appliances (UK voltage is currently specified as 230 V +10% / - 6%).

Frequency - The frequency in Thailand is 50 Hz which is the same as the UK.

Special considerations - "Sockets in hotels and most buildings are often a hybrid combination of types B and C which will accept plug types A, B, C and I, while outlets in older buildings are usually type A. Only Unearthed Type I plugs can be used in these hybrid sockets, earthed type I plugs will not fit. An equal proportion of appliances have type A or C plugs, or B if an Earth connection is required. Type E and F plugs have now been banned to stop them from being used in the new type O sockets (where the earth connection would not be made rendering it unsafe). The new type O sockets are now becoming more common."
