Disassembly report: mophie 45W dual C-Port fast charging charger

2022-06-11

Apple accessory vendor mophie is a well-known accessory manufacturer. It has launched a variety of protective cases, mobile power supplies and other accessories around the iPhone, and sold them in Apple's official online stores and physical stores. The quality has been fully recognized by consumers. The charging head network has obtained a 45W dual port PD fast charging charger launched by mophie. It adopts folding pins and has dual port independent 20W fast charging. It is 45W in single port output. It supports power blind plug and is very convenient to use and carry.

This 45W dual port charger can be used to charge iPad and iPhone with high power, and can also be used to quickly charge mobile phones when two iPhones are connected. The charging head network will disassemble the mophie dual C port charger to see how the materials and workmanship are.

Mophie's dual port 45W charger adopts a white shell, which has a round feel and is easy to carry with folded pins. With two usb-c interfaces, it can quickly charge two iPhones at the same time. The single port output 45W power can charge notebook computers, which is very practical. The output supports PPS fast charging and has good compatibility with Android phones, meeting the fast charging needs of mainstream brand phones.

Through the disassembly of the charging head network, it is learned that the process details of the mophie dual port 45W charger are very good. The PCBA module is glued for heat dissipation in a large area, and the input end uses four diodes to form a rectifier bridge, simplifying the heat dissipation design. Two PI highly integrated power chips are used internally to form two identical switching power supplies in combination with IC ip2726. In the case of single port output, the two power supplies are connected in parallel to achieve 45W output. In the case of simultaneous output of two ports, the two power supplies correspond to two interfaces, equivalent to two independent 20W chargers. Both interfaces support fast charging.

This dual port fast charging design greatly improves the compatibility of the charger. When using a single port, it can be used as a 45W charger to charge notebooks in case of emergency. When using a dual port, it can quickly charge two mobile phones at the same time. It only needs the support of the protocol chip, and two MOS tubes are added to connect the two power supplies in parallel, which reduces the waste of resources, and the design is very reasonable.
