Blue Sea 2 x USB-A Socket with Protective Cover, Rectangular is a powerful and intelligent charging solution designed for boats, RVs, and other 12 V or 24 V electrical systems. With two USB-A ports and smart device detection, it automatically adjusts output to deliver optimal charging performance for smartphones, tablets, GPS units, and other USB-powered devices. If you're looking for a USB upgrade that fits directly into an existing Contura-style cutout, this Blue Sea socket is designed for clean, professional installation in marine environments without the need for additional modifications.

Intelligent fast charging for two devices

The built-in Intelligent Device Recognition technology automatically detects connected devices and adjusts charging output accordingly. This ensures efficient, safe charging without manual setup or external adapters. With up to 4.8 A total output, the socket can charge two devices simultaneously at high speed while maintaining stable performance.

Designed for marine environments

The internal electronics are coated with a protective layer that helps resist moisture, salt, and corrosion. Integrated noise filtering reduces electrical interference, which is especially important near sensitive marine navigation and communication equipment. A protective cover keeps dust, dirt, and moisture away from the ports when not in use, extending service life in harsh environments.

Safe and easy installation

Built-in protection features include reverse polarity protection, short-circuit protection, and over-temperature protection, ensuring safe operation in all conditions. The unit installs directly into a standard Contura-style opening, making it a fast and visually clean upgrade for existing switch panels.
