This mini power box is designed to manage and distribute power from a 12V or 24V battery in your camper, boat or RV. Simply connect a high capacity 12/24V battery to its 50A high current battery connector input and power your 12/24V or USB powered devices from the two 50A high current battery connectors, two cigarette lighter power sockets, or from its five USB ports. Four USB-A ports provide up to 2.4A each, and a 60W USB Type-C port features Power Delivery technology to power or charge compatible devices. A built-in fuse box includes blade fuses to each power output, and a large 100A battery isolation switch enables you to easily turn the power on and off. An LED voltmeter indicates the voltage or your input battery.
