The Blue Sea Systems White 12/24V Dual USB 2.1A Charger Port (Model: 1016200 - BSS) is a must - have for mobile device charging. It fits into the same mounting hole as a traditional 12 - Volt outlet, making installation a breeze in existing 12V DC socket holes. Compatible with most mobile devices, including Apple® products, you can charge two devices on the go. It comes with a protective dust cap on a tether to prevent dust and spray from reducing the charger's lifespan. The conformal coated circuit board is built to withstand the tough marine environment. Note that the 2A supply fuse is not included. Key specifications: Total maximum output current of 2.1A DC, input voltage of 12V/24V, output voltage of 5V DC +/- 5%, cut - out dimension of 1 1/8 in (28.58 mm) dia. Hole, input voltage range of 9 - 32V, parasitic current draw of 15mA, and protection against reverse polarity, short circuit, and thermal overload. It features USB 2.0 technology.

Using this charger port is easy. First, find an existing 12V DC socket hole and install the charger. Make sure the input voltage of your power source is within the 9 - 32V range. Then, plug your mobile devices into the USB 2.0 ports and start charging. Remember, the charger can supply a total of 2.1A DC, so manage your device charging needs accordingly. When not in use, keep the protective dust cap on to protect the charger from dust and spray. This will help extend its lifespan. As for maintenance, there's not much to do. Just keep it clean and dry. Check the connections regularly to ensure a good charge. Also, note that the 2A supply fuse is not included, so if you need to replace it, get the appropriate one.
