No adaptor with you and already abroad? You’re not out of options — many airports and local shops sell them. Still, bringing your own is the simplest way to avoid paying over the odds or ending up with something that barely works.
Puerto Rico is commonly paired with visits to the Dominican Republic and The Bahamas. Plugs and sockets can vary a bit, so it’s worth double-checking before you go.
Sockets in Puerto Rico
Puerto Rico uses 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?
Don’t assume your gadgets will work straight away in Puerto Rico — the voltage isn’t the same as our 230 V, so a converter may be required.
Before using your gadget overseas, glance at the voltage mark. Anything showing ‘100–240 V, 50/60 Hz’ will be fine without a voltage converter.
