How East Asia changes a travel power plan
Japan, Taiwan, South Korea, mainland China, Hong Kong and Macau must not be treated as one plug or voltage system. Japan is also regionally split between 50Hz and 60Hz. Use a separate profile for every stop, especially when a single-voltage appliance is in the bag.
Evidence check: 1 of 7 destination profiles in this region are marked review required. That flag calls for a local or facility confirmation; the remaining profiles are also references rather than measurements of room outlets.
| Destination | Voltage reference | Frequency | Plug families |
|---|---|---|---|
| South Korea | 220V | 60Hz | Type C, Type F |
| Japan | 100V | 50/60Hz | Type A, Type B |
| China | 220V | 50Hz | Type A, Type C, Type I |
| Taiwan | 110V | 60Hz | Type A, Type B |
| Hong Kong | 220V | 50Hz | Type G |
| Macau | 230V | 50Hz | Type G |
| Mongolia | 220V | 50Hz | Type C, Type E |
For a US departure, a 120V-only appliance cannot be cleared by finding a familiar plug. Compare its exact INPUT range with every stop and use the multi-country kit planner for a conservative union of possible connector types.
How to use these pages
Compare each destination separately. Shared geography does not imply shared outlets, grounding or supply. Ask your accommodation about the exact outlet.
