Waterproof 12V Power Socket for External Mounting (Locking Cap)
This 12V power socket for flush/external installation is specifically engineered for reliable performance in marine environments. It is a standard “cigarette lighter” style receptacle, which allows you to plug in a wide range of accessories – phone chargers, 12V adapters for coolers, air pumps, navigation devices, and more. What sets this model apart is its fully watertight construction: when the cap is closed, no water can intrude into the socket; even when a matching locking plug is inserted, the system remains sealed thanks to a special collar around the opening. The “lock-in” mechanism works by twisting the plug upon insertion – it locks firmly so that vibrations from engines or waves won’t shake it loose unexpectedly. This makes the socket extremely suitable for fast powerboats and fishing vessels where equipment needs to stay plugged in during motion. Installation is flexible: you can mount it using a locking ring nut behind a panel cutout (standard diameter ~21 mm), or secure it from the front with two screws using its own rectangular flange (this option simplifies surface mounting if backside access is limited). The socket’s body is made of high-quality black plastic (polycarbonate/nylon) that resists impact and long-term UV exposure. The internal contacts are crafted from corrosion-resistant metal, ensuring long life and a secure, low-resistance electrical connection. For added convenience, this model is compatible with most standard automotive/marine plugs; if using a regular plug without the locking feature, the cap still helps hold it in, but for optimal waterproofing and retention it’s best paired with the locking plug from the same series.
- Use Cases: Install this socket on your boat’s console to power spotlights and GPS, on the deck for a portable fridge or pump, or in a car/truck trunk for camping gear
- For Boats & Vehicles: Suitable for marine vessels (yachts, RIBs, powerboats) as well as off-road vehicles and campers where exposure to water/dust calls for a reliable outlet
- Installation Tips: If using the nut, drill a ~21–22 mm hole; if surface-mounting with screws, consider sealing the flange with marine silicone for extra leak protection
- Max Load: The socket can handle high current loads (typically up to ~15A); make sure to install an appropriate fuse according to the device you’ll plug in
