The Anker - Laptop Charger (140W, 4-Port, PD 3.1) distributes power per USB port as follows: When One Port is in Use: USB-C1/USB-C2: 9V⎓3A, 15V⎓3A, 20V⎓5A, or 28V⎓5A (140W Max) USB-C3: 5V⎓3A, 9V⎓3A, 15V⎓2.65A, or 20V⎓2A (40W Max) USB-A1: 5V⎓3A, 9V⎓2A, 12V⎓1.5A, 10V⎓2.25A, or 11V⎓3A (33W Max) For additional usage of multiple ports, dynamic power allocation occurs: Two Ports: USB-C1 + USB-C2: 70W + 70W USB-C1 or C2 + USB-C3: 100W + 40W USB-C1 or C2 + USB-A1: 100W + 33W USB-C3 + USB-A1: Aggregate of 24W, distributed as 12W each port Three Ports: USB-C1 + USB-C2 + USB-C3: 65W + 45W + 30W USB-C1 + USB-C2 + USB-A1: Same as above USB-C1 or C2 + (USB-C3 + USB-A1): 100W + 24W (USB-C3 and USB-A1 share 24W) USB-C1+C2 + (USB-C3 + USB-A1): 65W + 45W + 24W Four Ports: USB-C1 + USB-C2 + USB-C3 + A: 65W + 45W + 12W + 12W Keep in mind the port priority for highest performance: USB-C1 > USB-C2 > USB-C3 > USB-A Make sure to connect high-power devices (e.g., laptops) to USB-C1 or USB-C2 for optimal performance.
