Saint Martin Power Plugs, Wall Sockets & Electrical Outlets
In Saint Martin, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded) and Type E (CEE 7/5, two round pins plus hole for socket grounding pin, grounded) are used. Wall sockets run at 220V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Saint Martin.

Understanding Saint Martin's Power Plugs and Sockets
A Saint Martin power plug typically comes in one of two forms: the two-pin Type C Europlug or the grounded Type E plug. The island's electrical supply runs at 220V and 60Hz, so travelers arriving from countries with different plug shapes or voltages will want to check their devices before plugging in. Both plug types are common throughout the territory, reflecting its shared French and Dutch heritage and the mix of European appliance standards found in local homes and hotels.
Is a Voltage Converter Necessary?
Since Saint Martin operates on 220V, visitors from regions with lower voltage systems should check whether their electronics are dual-voltage before use. Most modern phone chargers, laptop adapters, and camera chargers are built to handle a range of voltages and will work fine on the island without a separate converter. However, single-voltage appliances such as hair dryers or straighteners from a 110V country may require a proper voltage converter rather than just a plug top adapter, since a converter changes the electrical output while an adapter only changes the plug shape.
Grounding and the Earth Pin
Grounding matters most for higher-power appliances like kitchen equipment or power tools. Type E sockets found in Saint Martin supply grounding through a pin built into the socket-outlet itself, which enters a hole in the plug rather than the plug carrying its own earth pin. Type C Europlugs, by contrast, are ungrounded and rated only for low-power devices up to 2.5A, so they should not be used with appliances that require an earth connection.
Saint Martin Electrical Outlets Explained
Outlets across Saint Martin are generally compatible with both Type C and Type E plug tops, giving visitors some flexibility depending on what they're charging. A basic travel adaptor is usually all that's needed for phones, tablets, and laptops, while grounded appliances will specifically need a Type E-compatible plug to make full contact with the socket-outlet's earth pin.
- Type C (Europlug): two round 4mm pins, ungrounded, rated up to 2.5A, ideal for small electronics
- Type E: two round 4.8mm pins with a socket-based grounding pin, rated up to 16A, suited for higher-power and grounded appliances
- Voltage: 220V at 60Hz across the island
- Type C plugs fit into Type E sockets, though without grounding protection
Frequently Asked Questions
If your home country uses Type C or Type E plugs, you likely won't need an adapter at all. Travelers from countries with different plug shapes, such as those using flat-pin or three-pin designs, will need a travel adaptor to fit Saint Martin's round-pin sockets.
Some are and some aren't. Type E sockets used on the island are grounded and rated for 16A, with the earth connection provided by a pin in the socket itself, while Type C Europlug connections are ungrounded and limited to low-power devices up to 2.5A.
Yes, in most cases. Phone chargers are typically designed to accept a wide voltage range, so they'll work safely on Saint Martin's 220V, 60Hz supply using just a simple Type C plug or adapter without needing a voltage converter.
Pack a compact travel adaptor that supports Type C and Type E plug shapes, since both are common across the island. If you're bringing grounded appliances, make sure your adapter or plug top accommodates the Type E grounding pin rather than relying on an ungrounded Europlug.
