Overview
Both USB-C ports on this Anker charger are rated at 100W on their own, and the USB-A port at 33W. Anker publishes the split for every combination, including 80W + 12W + 7.5W with all three ports in use.
For a laptop plus phone, Anker lists 70W + 30W across the two USB-C ports. It can also run in a 95W + 5W mode, which with USB-A requires a low-current device on that port. At a stated 212g it is the heaviest wall charger here.
Best for: A powerful laptop plus a phone at a desk.
