Jamaica: Plugs, Voltage & Frequency
Type A/B · 110 V · 50 Hz
Jamaica uses Type A, Type B plugs and runs on 110 volts at 50 Hz. This guide covers what the sockets look like and exactly what you need to power your devices there.
Plug Types in Jamaica
- Type A — Type A is the flat, two-blade North American plug. The blades are parallel and unpolarized, with no ground pin.
- Type B — Type B adds a third round grounding pin below the two flat blades of Type A.
Voltage and Frequency
Jamaica operates on 110 V at 50 Hz. Wall outlets deliver this as standard mains power. USB chargers and most modern electronics accept a wide input range, but always check the rating printed on your device.
Traveler Note: Adapter or Converter?
You need a Type A plug adapter to fit Jamaica's sockets. Because Jamaica supplies 110 V, appliances built for 220-240 V need a step-down voltage converter unless they are labelled 100-240 V (most phone and laptop chargers are).
Frequently Asked Questions
Do I need a voltage converter or just an adapter for Jamaica?
You need a Type A plug adapter for Jamaica's sockets. A voltage converter is only required for devices that are not dual-voltage: Jamaica runs on 110 V at 50 Hz, so single-voltage 100-120 V appliances need a step-up converter and 220-240 V appliances need a step-down converter. Most phone and laptop chargers are 100-240 V and need only the adapter.
What plug type does Jamaica use?
Jamaica uses Type A, Type B. You may encounter more than one type in hotels and older buildings.
Can I charge my phone or laptop in Jamaica?
Almost certainly. Phone and laptop chargers are normally rated 100-240 V and only need a Type A plug adapter, not a voltage converter. Check the INPUT line on the charger to confirm.
