Summary of charging head network disassembly

NineBot No. 9 electric speed inflatable treasure consists of two parts: fuselage and battery, and the battery can be equated to the 10000mAh charging treasure, equipped with a 1A1C interface, and also has lighting lights. Usually, camping can charging battery life for user mobile phones, and when encountering emergencies such as changing tires at night, light sources can also be provided. In addition, as an electric tool, it supports 18W PD fast charging, which can be resurrected quickly with blood, which is also a highlight.

The design of the inflatable fuselage is very intelligent, equipped with tire pressure display and function keys to deal with preset memory functions in different scenarios, which can save common tire pressure. The inflatable becomes very convenient for users to take care of it and save effort and effort. In addition, with three professional inflatable mouths, up to a car, down to basketball, etc., can be inflated and widely used.

The charging head network was disassembled and found that the battery internal battery pack was composed of four power god LR1865SK power cells. It was equipped with a thermistor for temperature monitoring. In addition, there are two regulatory circuits. Nanxin SC8906 is responsible for charging battery packs. The SC8101 lowered voltage is USB output. In addition, the single -chip machine is used to drive the LED light and lighting light, and the function of the fuselage is also controlled by a single -chip microcomputer.
