beware, the maximum possible is 19.5W for one port.
Here are the product specs:

2 ports: Quick Charge 3.0 Output: 3.6-6.5V=3A, 6.5-9V=2A, 9-12V=1.5A

3 ports: PowerIQ Output: 5V=4.8A (2.4A Max Per Port)

so
max of a Quick Charge port: 6.5V x 3A = 19.5 W
max of PowerIQ ports: 5V x 4.8A = 24 W

so in total: 2 x 19.5 + 24 = 63W as in the description

Yes, the original power supply unit has a power rating of 61W :-)
