How Southeast Asia changes a travel power plan
A/B-shaped sockets in Thailand or the Philippines do not imply US supply voltage. Singapore and Malaysia have Type G references, while other destinations list several plug families across facilities. Ask each property for the actual socket rather than relying on a regional adapter label.
Evidence check: 3 of 10 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 |
|---|---|---|---|
| Vietnam | 220V | 50Hz | Type A, Type B, Type C, Type F |
| Thailand | 230V | 50Hz | Type A, Type B, Type C, Type O |
| Singapore | 230V | 50Hz | Type G |
| Malaysia | 230V | 50Hz | Type G |
| Indonesia | 220V | 50Hz | Type C, Type F |
| Philippines | 230V | 60Hz | Type A, Type B, Type C |
| Cambodia | 230V | 50Hz | Type A, Type C, Type G |
| Laos | 230V | 50Hz | Type A, Type B, Type C, Type E, Type F |

| Brunei | 240V | 50Hz | Type G |
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.
