Features Charging detection IC is compatible with all phone products. The input uses MOS tube reverse polarity protection, maximally increases conversion efficiency and reduces loss. It supports 4-channel USB for simultaneous charging with 2A current, large current and fast charging, the total output current can be up to 8A. Ultra wide input voltage of 8-35V, can perfectly support 12V and 24V car. The synchronous rectification scheme can effectively reduce heat, improve efficiency and the highest efficiency can reach 96%. Four channel independent special charging management IC, which can effectively support charging a variety of mobile phones. Features: Output has surge protection. Advanced flat choke coil with large current inductor, less heat, high conversion efficiency. Four high quality SMD capacitors and one MLCC capacitor with large capacity, lower output ripple. High quality double gold-plated USB port, the service life is 2 times that of ordinary USB. Supports mobile phones, digital cameras, tablet computers, navigation devices, vehicle data recorders and other USB powered devices. It can charge 4 mobile phones at the same time, maximum 2A for a single USB, total 8A for 4 channels. Different types of input and output methods, support terminal input, DC input, output support 4 x USB output, terminal output 5 V.
