Cayman Islands Power Plugs, Wall Sockets & Electrical Outlets
In Cayman Islands, power plugs and sockets (electrical outlets) of Type A (NEMA 1-15, two flat parallel pins, ungrounded) and Type B (NEMA 5-15, two flat parallel pins plus round grounding pin, grounded) are used. Wall sockets run at 120V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Cayman Islands.

Cayman Islands Electrical Outlets Explained
The Cayman Islands power plug setup follows the North American standard, using both Type A and Type B connectors throughout homes, hotels, and businesses. Type A is the ungrounded two-pin plug found on smaller devices, featuring two flat parallel pins that fit into a matching electrical outlet. Type B adds a round grounding pin to the same two-blade design, providing a safer grounded connection for larger appliances, computers, and power tools.
Every socket-outlet in the Cayman Islands is built to accept both plug types, since Type B outlets are backward compatible with Type A plugs. This means visitors from most of North America, Central America, and the Caribbean will find their existing plugs fit without any modification, as long as the voltage and frequency match their devices.
Voltage and Frequency in Cayman Islands
The Cayman Islands operates on a 120V electrical system running at 60Hz, matching the standard used in the United States and Canada. Devices rated for 100-127V will work normally, but appliances designed only for 220-240V systems will require a voltage converter in addition to any physical plug adapter.
Plug Sockets, Voltage & Adapters in Cayman Islands
Because the Cayman Islands uses the same Type A and Type B plugs as North America, travelers arriving from the United States or Canada typically need no travel adaptor at all. Visitors from countries with different plug standards, such as the UK, Europe, or Australia, will need a travel adapter to convert their plug shape to fit local sockets, though the voltage itself remains 120V and 60Hz throughout the islands.
Where to Buy a Travel Adapter for Cayman Islands
Travel adapters for Type A and Type B outlets are widely available at airport shops, electronics retailers, and luggage stores before departure, as well as online. It's best to purchase one before traveling, since selection at local Cayman Islands shops may be limited and geared toward outbound travelers rather than incoming visitors needing adapters for non-North American plugs.
- Type A plug: two flat parallel pins, ungrounded, used for small electronics and chargers
- Type B plug: two flat pins plus a round grounding pin, used for larger and grounded appliances
- Voltage: 120V at 60Hz, matching US and Canadian standards
- No adapter needed for US or Canadian plugs; a travel adaptor is required for other plug types
Frequently Asked Questions
If your devices use Type A or Type B plugs, as found in the US and Canada, you won't need a travel adapter in the Cayman Islands. Travelers from countries using other plug standards will need an adapter to fit the local electrical outlet, though the voltage remains 120V regardless.
The Cayman Islands runs on a 120V electrical system at 60Hz, the same as the United States. Devices built for 100-127V ranges will work fine, but equipment designed only for 220-240V will need a separate voltage converter.
Travelers from North America generally need nothing extra since their Type A and Type B plugs fit directly into local sockets. Visitors from other regions should pack a travel adaptor for Type A/B outlets, and anyone with 220-240V-only devices should also bring a voltage converter.
The Cayman Islands uses Type A and Type B plugs, both featuring two flat parallel pins, with Type B adding a round grounding pin for larger appliances. These match the plug standards used throughout the United States and Canada.
