Jamaica Power Plugs, Wall Sockets & Electrical Outlets
In Jamaica, 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 110V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Jamaica.

Power Sockets and Plug Types in Jamaica
Jamaica power plug standards follow the North American system, with electricity supplied at 110V and 50Hz. Travelers will encounter two main types of AC power plugs and sockets on the island: Type A and Type B. Both are widely used, so the plug type you need depends largely on the specific appliance or device you're bringing with you.
The Type A plug is the standard ungrounded two-pin design, featuring two flat parallel pins measuring 15.9mm apart. It's commonly used for small electronics, phone chargers, and low-power devices that don't require a grounding connection, and it's rated for 15A at 100-127V.
The Type B plug adds a round grounding pin to the same two flat parallel blades, making it the grounded counterpart used for larger appliances, computers, and power tools. Because a Type B socket-outlet is designed to accept both Type A and Type B plugs, most modern Jamaican wall socket fittings offer flexibility for a wide range of devices.
Do All Sockets in Jamaica Look the Same?
Not entirely. While many wall socket units installed in hotels and newer homes are the three-pin Type B variety, older buildings may still only have two-pin Type A sockets that lack a grounding connection. It's worth checking the outlet before plugging in sensitive or high-power equipment, especially in older properties.
Grounding and the Earth Pin
The earth pin found on Type B plugs is a safety feature that reduces the risk of electric shock by directing fault current safely away from the device. This round grounding pin is slightly longer than the flat power pins, so the ground connection engages before electricity flows. Devices requiring grounding, such as kitchen appliances or power tools, should always be paired with a properly grounded Type B outlet where possible.
Do You Need a Travel Adaptor for Jamaica?
If your home country uses Type A or Type B plugs and a 100-127V system, such as the United States or Canada, you likely won't need an adaptor at all. Travelers from countries using different plug standards, such as Type C or Type G, will need a simple adaptor to convert their plug shape to fit Jamaican sockets.
- Type A to Type B adaptor (if your device only has a two-pin plug and you want grounding)
- A universal travel adaptor covering Type A and Type B pin configurations
- A voltage converter only if your device isn't rated for 110V operation
Frequently Asked Questions
It depends on your home country's plug type. If you already use Type A or Type B plugs, such as travelers from the USA or Canada, no adaptor is needed. Visitors from countries using other plug standards will require an adaptor to fit Jamaica's sockets.
Jamaica uses both Type A and Type B plugs, operating on a 110V, 50Hz electrical system. Type A is the ungrounded two-pin version, while Type B adds a round grounding pin for added safety and is compatible with both plug types.
Pack a Type A or Type B adaptor if your devices use a different plug style, along with a universal adaptor for convenience. If your appliances aren't rated for 100-127V, you'll also want a voltage converter.
Yes, most modern phone chargers are dual-voltage and support 100-127V systems like Jamaica's, so a voltage converter usually isn't necessary. You may still need a plug adaptor if your charger's plug doesn't match Jamaica's Type A or Type B sockets.
