Summary of the dismantling of the charging head network
The Z70 Pro power bank has a built-in 70,000mAh lithium battery, which is several times the capacity of a conventional power bank. This power bank has greatly upgraded the charging and discharging performance, with a USB-C charging power of 65W and an output power of 100W, greatly shortening the self-charging time of the power bank. And it supports power supply for laptops, and the two USB-C ports output at the same time to support 65+35W automatic power allocation, which greatly enhances the practicality.
Through dismantling, the charging head network learned that the mobile speed Z70 Pro mobile power bank has 6 strings of 11700mAh lithium polymer batteries connected in series, and the Chuangxin Micro CM1361 battery protection chip is used for battery overvoltage, undervoltage and overcurrent protection. The main control of the mobile power supply adopts Silan micro-SD59D24B, the chip has built-in protocol functions, and supports the use of four USB interfaces.
The chip also integrates two synchronous buck-boost controllers, which are used for USB-C1 interface and USB-C2 and USB-A interface output. The synchronous buck-boost inductor is magnetically surrounded and insulated with heat shrinkable tubing. Solid-state capacitor filtering is used on both the battery and output terminals to reduce output ripple. The battery pack is fixed with double-sided tape on a large area, and the foam glue cushion is pasted on the edge of the battery to improve safety.
