Trinidad & Tobago Power Plugs, Wall Sockets & Electrical Outlets
In Trinidad & Tobago, 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 115V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Trinidad & Tobago.

Power Sockets and Plug Types in Trinidad & Tobago
The Trinidad & Tobago power plug system relies on two North American plug standards: Type A and Type B. Every electrical outlet across the islands is built to accept these flat-pin plug designs, so travelers arriving from regions using round-pin plugs will need an adapter to plug in their devices. Homes, hotels, and businesses throughout Trinidad and Tobago are wired for 115V at 60Hz, matching the standard used in the United States and much of the Caribbean.
Type A plugs feature two flat parallel pins and are commonly used for small, ungrounded electronics such as phone chargers, lamps, and other low-power devices. Type B plugs add a round grounding pin alongside the same two flat blades, providing extra safety for larger appliances, computers, and power tools. Because every Type B wall socket also accepts Type A plugs, most visitors find their devices fit without difficulty as long as the pin shape matches.
Dual-Voltage Devices and Trinidad & Tobago
Many modern electronics, including laptop chargers, phone adapters, and camera battery chargers, are dual-voltage and can automatically handle the 115V, 60Hz supply found in Trinidad & Tobago. Checking the label on your charger or power adapter for a voltage range such as '100-240V' confirms whether it will work safely without a separate voltage converter. If a device is not dual-voltage, a converter is necessary in addition to a plug adapter, since an adapter alone only changes the plug shape and not the electrical current.
Grounding and the Earth Pin
Grounding is an important safety consideration for higher-powered devices, and this is where the Type B 3-pin plug comes in. The additional round grounding pin on a Type B plug is longer than the two flat power pins, so it connects to the earth first before the device receives any power. This grounding feature is typically required for kitchen appliances, bathroom fixtures, and outdoor or garage circuits, offering protection against electrical faults that a simple two-pin Type A plug cannot provide.
What Plug Type Does Trinidad & Tobago Use?
Trinidad & Tobago uses Type A and Type B plugs, the same flat-pin standards found throughout North America. Type A plugs are the two-pin, ungrounded version rated for up to 15A at 100-127V, while Type B plugs add a rounded grounding pin for appliances that require an earth connection. Since Type B outlets accept both plug types, travelers with either style of plug can generally connect their devices without needing to seek out a specific socket type.
- Type A: two flat parallel pins, ungrounded, used for small electronics
- Type B: two flat pins plus a round grounding pin, used for larger or grounded appliances
- Voltage: 115V at 60Hz
- Type B outlets accept both Type A and Type B plugs
Frequently Asked Questions
If your devices use Type A or Type B plugs, no adapter is needed since these are the standard plug types used throughout Trinidad & Tobago. Travelers with round-pin or other plug styles will need a plug adapter to fit the local flat-pin electrical outlets.
Many sockets in Trinidad & Tobago are the grounded Type B variety, which includes a round earth pin alongside the two flat power pins. However, ungrounded Type A outlets are also common, particularly for smaller devices that don't require a grounding connection.
Trinidad & Tobago operates on a 115V electrical supply at 60Hz frequency. This matches the standard voltage used across much of North America, so devices designed for 100-127V systems will work without a converter.
Trinidad & Tobago uses Type A and Type B plugs, both featuring flat parallel pins, with Type B adding a round grounding pin for safety. These are the same plug standards used in the United States, Canada, and much of Central America.
