From Antigua and Barbuda to Thailand
When travelling from Antigua and Barbuda to Thailand: Good news: all your Antigua and Barbuda plug types fit in Thailand. Voltage is different (110V / 220V → 230V). Check your charger label; if it doesn’t list 230V you’ll also need a voltage converter. Frequency differs (60Hz → 50Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.

About electricity in Thailand
Thailand uses 230V/50Hz with Type A, B, C, and O sockets. Most modern outlets accept all four, so most travellers will not need an adapter at all.
Grid & history
EGAT operates the national grid. Natural gas is the largest source, with growing solar and hydropower imports from Laos. Reliability has improved markedly over the last decade.
Availability
The grid is reliable in Bangkok and major tourist areas, though the rural north and the islands can see brief outages during the rainy season.
Sockets & hotels
The “universal” socket common in hotels accepts US flat blades (Type A), grounded US (Type B), European round pins (Type C), and the Thai three-pin (Type O). Older buildings and street-front guesthouses may have only A and B.
Energy mix
Natural gas dominates; solar and hydro imports growing.
Practical tips
- Most US and European chargers fit Bangkok hotel sockets without any adapter.
- Voltage is 230V, so US-only hair dryers will burn out. Check the label for “100 to 240V” before plugging in.
- On the islands, expect occasional brief outages, and bring a small power bank for the longer ones.
