The ChargeView 140W Desktop Charger has four USB-C ports with different charging standards:

• Port C1: USB PD (Power Delivery) 3.2 with AVS (Adjustable Voltage Supply). This is the fastest port, so it is best for your highest-power device, such as a laptop or a recent iPhone.
• Ports C2, C3, and C4: USB PD (Power Delivery) 3.1 with PPS (Programmable Power Supply).

All four ports can charge at the same time, and the charger automatically distributes power based on what each connected device needs. Used on its own, Port C1 or Port C2 can deliver up to 140W, while Port C3 and Port C4 each deliver up to 40W.
