120W Desktop Power Supply
PinePower Desktop 120W render
A 120W desktop power adapter. It features 1 USB-C port and 4 USB-A port. The 120W output is not per port, but total output power. This is calculated by combining the 65W USB-C, 3x15W USB-A and the 18W USB-A QC, making a total of 128W. The only difference between the US and EU edition is the supplied power cable. Every port, with exception of the wireless Q-charger, has a display, portraying the output voltage and amps. The display back light can be turned on and off by capacitive touch button, located on the top left side of the unit.

Internals
The power unit is not made to be disassembled, do so at your own risk. The front plate is secured with 4 tabs, that can be disengaged with a screwdriver. The complete assembly can be slid out, but do mind the same tab in the casing. The power button at the back of the case has a plug that can be disconnected from the main PCB. The wireless charging PCB has to be de-soldered, or forcefully removed from the inner casing, as it is glued to the top of the case.

Some remarks:
- This main PCB is marked as XR SEMI v1.1
- Two unmarked packages, control the display.
- An antenna is connected on the display PCB, lining up with the ’lamp’ symbol. This is the capacitive touch button to control the display back light.
- The 65W PD USB-C port is controlled by a HUSB339 controller, paired with a GOFORD G16 MOSFET.
- The other ports have a NDP1360KC as final power converter.
