Preface

The charging head network got a fast-charging power bank with its own wire, which has a built-in 20,000mAh capacity battery and supports 22.5W fast charging. The power bank comes with a USB-C cable, which can be used to connect to the mobile phone for charging, or it can be connected to the charger to charge the power bank.

The Anker power bank has a percentage battery display and also has USB-A and USB-C ports. There is a stand on the side of the fuselage, which can be used to place the mobile phone, which is convenient for watching videos on the horizontal screen. Let's bring a dismantling of Anker's self-wired mobile power supply, and take a look at the internal materials and design.

Summary of the dismantling of the charging head network

Anker's built-in wired fast charging power bank has a built-in 20,000mAh battery, which can provide multiple charges for the phone on a single charge, and has a strong battery life. The power bank comes with a USB-C cable, and the output is to charge the mobile phone, or to charge the power bank, you can use the own cable to complete, eliminating the trouble of carrying a data cable. It also has USB-C and USB-A ports to meet the charging needs of traditional devices.

Through the dismantling of the charging head network, it was learned that Anker's mobile power bank has two built-in batteries connected in parallel, and double-sided tape is pasted on the side of the battery for buffer protection. The battery is equipped with a thermistor and a protection plate for temperature and overcharge and overdischarge protection. The power bank has a built-in Nanxin Technology SC8933 boost converter for fast charging output, with the use of Xinhai Technology CSU3AF10 for interface protocol control, and CSU32P10 for LED digital tube display driver.
