Disassembly report: mophie 65W 1a1c Gan fast charging charger

2021-04-19

As a long-term partner of apple, mophie has been continuously launching high-quality products such as wireless charger, back clip and mobile power supply, which have been recognized by the majority of consumers. Recently, mophie officially set foot in the Gan fast charging market and launched a 65W dual port fast charging Gan charger.

This charger body is small and round, and the 1a1c interface supports 18W + 45W charging strategy, which can meet the fast charging requirements of two devices at the same time. Next, the charging head network will be disassembled in detail to see how the charger is doing.

Mophie's 65W Gan charger tends to be square from one side, with the same length and width. In addition, the surface of the fuselage shell is frosted, and the edges and corners are curved, which makes it easy to get started. The charger is equipped with foldable pins, which is convenient for business trip. In addition, it is equipped with 1a1c two universal oil interfaces, which can be compatible with more devices, and the maximum 65W fast charging can make the device full of blood quickly.

Through the disassembly of the charging head net, we learned that a large amount of glue is applied on the front and back of the PCB board, and a large area of heat sink is covered at the same time, so as to improve the overall stability and heat dissipation performance of the product. The input and output terminals are equipped with small boards, which can make full use of the internal space and reduce the volume of the charger. The product adopts the popular switching power supply and secondary pressurization structure.

The switching power supply is composed of Anson ncp1342 with nano micro Gan power chip and MPs mp6908a with Wandai synchronous rectifier. The output voltage of C port and a port is controlled by the British chip ip2723t and ip2163 respectively, but after synchronous rectification, the usb-a port also uses the South chip sc8903 for voltage up and down conversion.
