Image: A diagram illustrating the power output distribution across the four ports (C1, C2, C3, A) when one, two, three, or four devices are connected simultaneously. For example, C1 and C2 can each deliver 100W when used alone, but when all four ports are in use, power is distributed as 45W (C1), 30W (C2), 7.5W (C3), and 7.5W (A).
Single Port Usage:
- USB-C1 or USB-C2: Up to 100W Power Delivery (PD 3.0) for laptops like MacBook Pro 16".
- USB-C3: Up to 20W Power Delivery (PD 3.0) for smartphones and smaller tablets.
- USB-A: Up to 18W Quick Charge (QC 3.0) for compatible devices.
Multi-Port Usage:
- When multiple devices are connected, the charger intelligently adjusts power output to each port. Refer to the power distribution diagram for specific output scenarios.
- For optimal fast charging of high-power devices like laptops, use USB-C1 or USB-C2.
- PPS Charging: USB-C1 supports PPS (Programmable Power Supply) for super-fast charging compatible Samsung devices (e.g., Galaxy S21 Ultra 66% in 30 minutes). When C1 and C2 are both used, only C1 supports PPS (Max 45W).
