On the ChargeView 140W Desktop Charger, AVS and PPS are both fast-charging technologies that fine-tune power for your device.

• AVS (Adjustable Voltage Supply) is part of USB PD (Power Delivery) 3.2 and allows finer voltage adjustments for more efficient charging. It is used on Port C1 for the fastest charge to the newest devices, including recent iPhones.
• PPS (Programmable Power Supply) is part of USB PD (Power Delivery) 3.1 and adjusts voltage and current in real time for compatible devices. It is used on Ports C2, C3, and C4.

Both help optimize charging speed and efficiency for whatever device you connect.
