Charging head network disassembly summary
Aohi MAGCUBE W4000 magnetic wireless charging mobile power supply continues the exquisite appearance design tradition of this series of products, very small and elegant, the USB-C port is decorated with metal rings and is equipped with three-color power breathing indicator lights. The product is very light and thin, with an ultra-thin glossy glass panel design on the back, which has a stronger suction force and supports iPhone 12/13 series models with a shell magnetic charging, which is very convenient.
is also very small and exquisite, not only beautiful and comfortable to use, but also does not block the hands or the lens. It is more natural to play games and take photos while charging magnetically. The product not only supports 0W Qi magnetic wireless charging, but also supports 20W PD two-way fast charging, which can give iPhone 12/13 users a good charging experience and very practical performance.
charging head network learned through disassembly that a large amount of thermal glue is filled with inside the product to help dissipate heat, and at the same time, the battery cell and coil are equipped with a thermistor for temperature monitoring to ensure that low-temperature charging does not damage the mobile phone.
In order to achieve the ultimate compactness, the power bank adopts the well-known brand Lishen high-voltage platform high-energy density cobalt formula battery cell, and also adopts a stacking design of two small boards to make use of the internal space as much as possible. In addition, the Yingjixin IP5332 all-in-one SOC chip and IP6808 wireless charging solution are adopted, and the integration is very high. The required circuit board is very small, which also effectively helps the power bank to achieve miniaturization. In general, the product materials are very reliable.
It is worth mentioning that the charging head network has also disassembled the Aohi Magcube series 65W PD fast charging gallium nitride charger, mini 30W gallium nitride charger, mini 20W PD fast charging charger and other products. Welcome to check it out.
