Santo Domingo is often visited alongside Haiti and Puerto Rico. It’s smart to double-check plug types before you travel — they can differ slightly.
Sockets in Santo Domingo
The plug types you’ll find in Santo Domingo are 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.
Do You Need a Voltage Converter?
Some of your kit may need a voltage converter in Santo Domingo, since the local mains doesn’t line up with Britain’s 230 V.
Have a look at your device’s voltage label before plugging in abroad. If it says ‘100–240 V, 50/60 Hz’, there’s no need for a converter — laptops, tablets and other modern gadgets usually have this built in.
