Do I Need a Plug Adapter for Thailand from the UK?

Yes, you'll need an adapter.

UK and Irish plugs (Type G) don’t fit the sockets in Thailand (Type A, B, C, O). The voltage is similar (230 V at home, 230 V there), so you won’t need a voltage converter for devices rated for your home voltage.

Voltage check

The voltage is similar (230 V at home, 230 V there), so you won’t need a voltage converter for devices rated for your home voltage. Most phone, tablet and laptop chargers say 100–240 V on the label; treat that as something to check, not a guarantee. Read plug adapter vs voltage converter for how to read a label.

Socket details for Thailand

Our data lists five socket types for Thailand: Type A, B, C, F and O. Rooms and buildings differ, so the socket in front of you may be any of these.
A two-pin Type C plug fits the sockets in Thailand, according to the plug-fit rules in our voltage checker (Type C fits Type C, E, F and L sockets).
Your plugs from the UK and Ireland are Type G (three rectangular); in our plug-fit rules they fit Type G sockets, which the voltage checker lists for places such as UK, Ireland, HK, Singapore, Malaysia.

What to pack

A plug adapter for Type C sockets (one per device you’ll charge at the same time)
Check the label on each charger: look for “100–240V” or “INPUT: 100–240V ~ 50/60Hz”
A Type C (two round pins) adapter as a backup for older sockets
A power board or multi-port USB charger from home means you only need one adapter

Questions

Do I need a plug adapter for Thailand from the UK?

Yes, you'll need an adapter. UK and Irish plugs (Type G) don’t fit the sockets in Thailand (Type A, B, C, O).

What plugs does Thailand use?

Thailand uses Type A, B, C, O sockets at 230 V, 50 Hz (Aorista voltage checker data).

Do I need a voltage converter for Thailand from the UK?

The voltage is similar (230 V at home, 230 V there), so you won’t need a voltage converter for devices rated for your home voltage. Most phone and laptop chargers are labelled 100–240 V, but check yours before you plug it in.

Will my phone charger work in Thailand?

If its label says 100–240 V, it can be used at 230 V; you still need a plug adapter for the socket.
