ChargerLAB POWER-Z KM003C shows the USB-C1 can support PD3.1, DCP, and Apple 2.4A charging protocols.
And it has five fixed PDOs of 5V3A, 9V3A, 15V3A, 20V5A, and 28V5A. It also has a set of AVS, which is 15-28V 140W.
ChargerLAB POWER-Z KM003C shows the USB-C2 can support PD3.0, DCP, and Apple 2.4A charging protocols.
And it has four fixed PDOs of 5V3A, 9V3A, 15V3A, and 20V5A.
The protocols compatible with USB-C3 are the same as those of USB-C2.
So as the PDOs.
It is measured that the compatible protocols of the USB-C4 port are the same as those of the previous two ports.
So as the PDOs. The performance of USB-C2, USB-C3, and USB-C4 ports is the same.

Summary of ChargerLAB
Here is the component list of the ANKER 150W 4 Ports GaN Charger for your convenience.
Its design style is simple, and the shell is made of PC flame-retardant material, which is safe and reliable. The surface is matte and feels very good to the touch. Compared with competing products on the market, its biggest feature is that each interface can support high-power fast charging of more than 100W, and the performance is quite impressive.
As an Apple-exclusive version, the only compatible protocol is PD fast charging. However, compared with Apple's original 140W GaN fast charging, it has advantages in size, number of ports, and performance. It is very suitable for Apple multi-device users to purchase and is suitable for daily home office and travel use.
After taking it apart, we found it uses PFC+AHB power architecture design. In addition, the PCBA module is filled with potting compound to improve heat dissipation, and heat sinks are added to the bridge rectifier, PFC boost inductor, and even the shell to help dissipate heat. Whether it is the overall or the details, the materials and workmanship of this product by Anker are quite good.
