Here's why:
* Voltage: The Dominican Republic uses 110 volts, the same as the US. However, the frequency is different: the DR uses 60Hz, while the US uses 50Hz. This difference can damage your appliances.
* Plug Type: The Dominican Republic uses Type A plugs, which are the same as in the US. However, they also use Type B plugs, which have an additional grounding pin.
What you need:
* Voltage Converter: This isn't strictly necessary since the voltage is the same, but some appliances might be sensitive to the frequency difference.
* Plug Adapter: You'll need an adapter to convert the plug type. You can find these at most electronics stores or online.
Important Note:
Even with a voltage converter and adapter, it's always a good idea to check the specific requirements of your appliance. Some items, like hair dryers and electric razors, may not work properly or be damaged with a voltage converter.
