Asia has some of the most diverse electrical standards in the world. Different countries use different voltages, frequencies, and plug types. This guide will help you prepare.
Overview by Country
| Country | Voltage | Plug Types |
|---|---|---|
| Japan | 100V / 50-60Hz | Type A, B |
| China | 220V / 50Hz | Type A, C, I |
| Thailand | 220V / 50Hz | Type A, B, C, O |
| Singapore | 230V / 50Hz | Type G |
| Hong Kong | 220V / 50Hz | Type G |
| India | 230V / 50Hz | Type C, D, M |
| South Korea | 220V / 60Hz | Type C, F |
Country-Specific Tips
Japan
Special case: Japan uses only 100V - the lowest in the world. Most dual-voltage devices (100-240V) work fine, but single-voltage 220V devices won't work even with an adapter.
US/Canadian travelers: Your Type A/B plugs fit Japanese outlets directly! No adapter needed for most devices.
China
China uses a mix of plug types. Many outlets accept multiple plug styles. A universal adapter is recommended.
Thailand
Thai outlets often accept both Type A (US) and Type C (European) plugs. However, having an adapter ensures compatibility with all outlets.
Singapore & Hong Kong
Former British colonies use Type G (UK) plugs. If coming from the UK, your devices work directly. Others need a Type G adapter.
