Recently, from http://www.chongdiantou.com/, it is learned that Bull, a leading brand in the domestic socket industry, releases a cube socket with three USB fast charging interfaces. The latest multi-port fast charging protocol chips FP6601A and FP6601A of Fitipower are in it. It supports 18W fast charging output, and the powers of the three interfaces are distributed intelligently.

Bull fast charging cube USB socket is equipped with three 3+2-bit jacks and three USB-A output interfaces. The AC supports a maximum power of 2500W. In the DC part, the three USB interfaces support 18W fast charging at most when they output alone, They are compatible with various charging protocols such as Apple 2.4A, Samsung 5V/2A, DCP, QC2.0/3.0, AFC and FCP. The powers are distributed intelligently when several interfaces output. It can meet the daily charging requirement of most mobile phones.

The USB output part of Bull fast charging cube socket adopts switching power supply and protocol identification. Two protocol identification chips, FP6601A and FP601AA, are used for the three USB interfaces, among which FP6601A is used for the protocol control of a USB interface and FP6601AA is used for the protocol control of the other two USB interfaces. The two chips can communicate with each other, which achieves the function that there is 18W fast charging  in any interface when the interface output alone and the power reduces intelligently when several interfaces output.

The summary of http://www.chongdiantou.com/

The multi-port output scheme of Bull fast charging cube USB socket is different from the common secondary voltage-reducing multi-port scheme. It directly achieves the power coordination of many interfaces through the communication between two protocol chips FP6601AA and FP 6601A. Compared to the secondary voltage-reducing scheme, Fitipower multi-port fast charging scheme omits devices such as buck chips and buck inductors. When it is used for the development of 18W multi-port fast charging products, it has more cost advantage.
