4K at 30 Hz is the number to know before buying, and it is not on the front of the box.
Full details →Who the Anker 737 Charger 120W GaN Prime 3-Port Wall Fast Charger is for
Buy it if: Anyone charging a laptop and phone from one adapter who understands the power is shared.
Avoid it if: Anyone expecting full speed on every port simultaneously -- no multi-port charger does that.
Who the Anker 555 USB-C Hub 8-in-1 PowerExpand Adapter is for
Buy it if: Anyone needing many ports at 1080p or 1440p, or 4K where refresh rate does not matter.
Avoid it if: Anyone driving a 4K monitor for daily work -- 30 Hz pointer stutter is genuinely unpleasant.
