Puerto Rico Travel Adapters
Type A and Type B • 120 volts • 60 Hz
Puerto Rico was once home to the world's largest single-dish radio telescope. The Arecibo Observatory, built in 1963 for ionospheric radar research, spent decades as a landmark of radio astronomy and pop culture, appearing in films like Contact and GoldenEye. On December 1, 2020, its support cables failed and the 900-ton instrument platform crashed into the dish below, ending the observatory's operating life for good.
Puerto Rico is a territory of the United States in the Caribbean located east of the Dominican Republic and west of the Virgin Islands. The capital city is San Juan. Major destinations include San Juan, Ponce, and Rincon. Puerto Rico is known for its beaches, rainforests, and vibrant culture.
Puerto Rico uses mains electricity supplied at 120 volts at 60 Hz. Wall outlets use Type A and Type B plugs, the same as the United States. Travelers from regions that use different plug types should bring a compatible travel adapter. Visitors should confirm that their devices support 100–240V input or use an appropriate voltage converter if necessary.

Adapter may also be spelled adaptor. Converter may be spelled convertor. Grounded may also be described as earthed.
Puerto Rico uses Type A and Type B outlets, identical to the United States, since Puerto Rico is a US territory on the same electrical grid standard. Travelers coming from the US mainland need no adapter or converter at all.

Do I need a voltage converter for Puerto Rico?
No, in most cases. Puerto Rico uses the same 120V, 60Hz electrical system as the US mainland, so US devices and chargers work without a voltage converter or a plug adapter. Travelers arriving from outside the US will still need a universal travel adapter to convert their home country's plug into Puerto Rico's Type A and Type B outlets.
Can I use my US phone charger in Puerto Rico?
Yes. Puerto Rico uses the same Type A and Type B outlets and the same 120V, 60Hz supply as the US mainland, so a US phone or laptop charger plugs in directly with no adapter or converter needed.
Are Puerto Rico and US power outlets interchangeable?
Yes. As a US territory, Puerto Rico uses the identical Type A and Type B outlets and the same 120V, 60Hz voltage and frequency as the mainland United States, so there's no need for an adapter or converter when traveling from the US.
Does Puerto Rico use more than one plug type?
Yes, the same two types used throughout the US: Type A, a two flat-pin plug, and Type B, which adds a third round grounding pin. Devices with either plug work in Puerto Rico's outlets without an adapter.
