Introduction
---------------------------------------------------------------
Not long ago, ChargerLAB took apart several USB-C GaN chargers from DELL, which only support PD3.0. This is the first time for us to get a DELL 165W GaN power adapter that supports PD3.1.
And we are going to take it apart to see what the internal components look like after supporting PD3.1.
