Martinique Power Plugs, Wall Sockets & Electrical Outlets
In Martinique, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded), Type D (BS 546, three large round pins in triangular pattern, grounded) and Type E (CEE 7/5, two round pins plus hole for socket grounding pin, grounded) are used. Wall sockets run at 220V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Martinique.

What Plug Type Does Martinique Use?
The Martinique power plug setup relies on two standard European plug types: Type C (the Europlug) and Type E, the French grounded standard. As an overseas territory of France, Martinique follows French electrical conventions, meaning most local AC power plugs and sockets are designed to accept either of these two plug styles. Type C plugs are used for smaller, double-insulated electronics, while Type E plugs handle larger appliances that require a grounded connection.
Voltage and Frequency in Martinique
Electricity in Martinique is supplied at 220 volts and 50Hz, consistent with the rest of the French electrical system. This differs from the 110-120V systems used in the United States and other parts of North America, so travelers from those regions should check whether their devices support 220-240V input before plugging in. Most modern electronics, including phone and laptop chargers, are built to handle this voltage range automatically.
Grounding and the Earth Pin
Type E sockets found in Martinique use a distinctive grounding method: rather than the plug carrying a grounding pin, the wall socket-outlet itself has a protruding pin that fits into a corresponding hole on the plug. This CEE 7/5 design delivers reliable 16-amp grounded protection for appliances like kitchen equipment and power tools. Ungrounded Type C Europlugs can still be inserted into these sockets, but they won't receive any grounding protection, which is fine for low-power, double-insulated devices.
Power Sockets and Plug Types in Martinique
Visitors packing for Martinique should be prepared for outlets that accept round-pin plugs only, since flat-pin plug types used in the UK, US, or Australia will not physically fit. A compact travel adaptor covering Type C and Type E is the simplest solution, and many universal adaptors sold for continental Europe will work perfectly here. Below is a summary of the two plug types encountered on the island.
- Type C (Europlug): Two round 4mm pins, ungrounded, rated up to 2.5A at 220-240V. Best for phones, tablets, cameras, and other low-power Class II electronics.
- Type E: Two round 4.8mm pins with a socket-based grounding pin, rated up to 16A at 220-240V. Used for higher-power appliances requiring an earth connection.
Frequently Asked Questions
If your home country uses Type C or Type E plugs, no adapter is needed. Otherwise, you'll need a travel adaptor to convert your plug's pins to fit Martinique's round-pin Type C or Type E sockets.
Yes, many sockets in Martinique are the grounded Type E standard, which uses a protruding pin in the socket-outlet to provide a 16A earth connection. Ungrounded Type C Europlugs are also compatible with these outlets for low-power devices, though without grounding protection.
Martinique uses Type C (Europlug) and Type E plugs, both operating on a 220-240V, 50Hz system. Type C is for smaller ungrounded electronics, while Type E provides grounded connections for larger appliances.
Most phone chargers are dual-voltage and can handle Martinique's 220V, 50Hz supply without a converter. You'll just need a Type C or Type E plug, or a travel adaptor, since a voltage converter typically isn't necessary for modern phone charging equipment.
