Summary of ChargerLAB

This HP 65W dual USB-C GaN power adapter adopts a black matte design with two detachable cables. The grounding prong inside the input socket can protect the user from electric shock.

After taking it apart, we found the PCBA module is wrapped with copper sheet for better heat dissipation performance. It uses Transphorm GaN FET, and the primary controller is from Weltrend. The protocol chip is from Infineon CCG7DC series.

The GaN component can effectively increase the efficiency of the adapter and reduce heat generation during fast charging. Compared with 170 mΩ GaN of other companies, it adopts 240 mΩ GaN from Transphorm and still achieves high efficiency.
