Sockets in the Dominican Republic
In the Dominican Republic, you’ll find Type A and B plugs and sockets.
Type A

Type A sockets have two flat parallel pins and no grounding. Unlike Type G, they don’t include an earth pin, which makes them less secure.
Type B

Type B sockets have two flat parallel pins plus a round grounding pin. Unlike Type G, the pins are thinner and there’s no built-in fuse.

Didn’t pack an adaptor? You can still grab one when you arrive. Still, it’s better to bring your own than risk paying too much for something unreliable.
The Dominican Republic is commonly paired with trips to Haiti and Puerto Rico. Check the plug info for those countries too — they may not match exactly.
Do You Need a Voltage Converter?
A converter could be necessary in the Dominican Republic because the voltage there differs from the UK standard of 230 V.
Double-check your device’s voltage label when travelling. ‘100–240 V, 50/60 Hz’ means you won’t need a converter, which is the case for most up-to-date electronics.
