From Antigua and Barbuda to Jamaica
When travelling from Antigua and Barbuda to Jamaica: Good news: all your Antigua and Barbuda plug types fit in Jamaica. Voltage is different (110V / 220V → 110V). Check your charger label; if it doesn’t list 110V you’ll also need a voltage converter. Frequency differs (60Hz → 50Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.

About electricity in Jamaica
Jamaica is 110V at 50Hz. An unusual combination, with Type A and B sockets.
Grid & history
Jamaica’s grid runs on a mix of natural gas, heavy fuel oil, and growing solar/wind (Wigton wind farm, Content solar). The 110V/50Hz combination is a legacy quirk that can affect 60Hz-tuned US gear (motors and clocks).
Availability
Reliable in Kingston and tourist areas; outages can occur during hurricane season.
Sockets & hotels
Standard North American Type A/B sockets.
Energy mix
Practical tips
- US plugs fit Jamaican sockets directly.
- Voltage is 110V like the US, but frequency is 50Hz, so US clocks and some motors will run ~17% slow.
