Summary of the dismantling of the charging head network

This power bank is designed with its own cable, with USB-C and Lightning output cables, which supports charging laptops and mobile phones, and can also be directly connected to the charger to charge the power bank. The power bank has a 188 digital tube power display, which accurately displays the battery percentage, and the remaining power of the power bank is more intuitive. And with the built-in AC input, it can charge the power bank without a charger, which is easy to use.

Through the dismantling of the charging head network, it was learned that Weierpu's mobile power supply has two built-in strings of 10000mAh batteries, and the battery pack comes from Guangdong Weilian Electronic Technology Co., Ltd. The power bank is built with a CPW6410 SOC chip of Xinhai Technology, which integrates a variety of fast charging protocols such as PD3.1 and UFCS, high-performance MCU, synchronous bidirectional buck-boost management, lithium battery charging management, supports 2-6 strings of lithium battery applications, and supports the use of dual USB-C ports.

The built-in switching power supply of the mobile power supply adopts the integrated power supply scheme of Anbaogao, and adopts the OB2500 primary main control chip with the OB2005 synchronous rectifier chip, the primary side feedback, and the fixed voltage output. The battery inside the power bank is insulated with barley paper, and a thermistor is pasted to detect the temperature. The CPW6410 SOC chip greatly simplifies the design of multiple strings of high-power mobile power banks, and is a highly integrated solution.
