Dominican Republic uses Types A, B and C plugs, 120V at 60Hz. Travelling from the UK you need a plug adapter and a voltage converter for appliances that are not dual-voltage. Phone and laptop chargers are usually rated 100-240V, so they only need the right plug.
| Plug type | Types A, B and C |
| Type A | two flat parallel pins |
| Type B | two flat pins plus a round earth pin |
| Type C | two round pins (Europlug) |
| Voltage | 120V |
| Frequency | 60Hz |
| Travelling from | Home plug | Adapter | Voltage converter |
|---|---|---|---|
| United Kingdom | Type G, 230V | Needed | Needed for single-voltage appliances |
