Teardown of MOVESPEED 140W PD3.1 4-in-1 Charger (YSFCG107-140Y)
Introduction
ChargerLAB had done multiple tests on the MOVESPEED 140W PD3.1 charger. It can meet the charging needs of most devices. It also supports automatic power distribution and can charge four devices at the same time.
This time, we got its yellow version. To know how it can achieve a charging performance like that, we are going to take it apart to see its internal components and structure.

Summary of ChargerLAB
The MOVESPEED 140W PD3.1 charger has a rounded case and a yellow matte surface. It is equipped with four ports and comes with a dual USB-C cable.
After taking it apart, we found it adopts a PFC circuit and flyback topology. It also adopts three independent buck circuits to achieve four-port fast charging and automatic power distribution. The PCBA module is wrapped and insulated with mylar sheets and copper sheets. And it is filled with pounding compound. The internal structure is compact, which effectively saves space. All of these makethe charger smaller than the Apple 140W charger, with even more ports.
