Full details →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.
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.

| Ethernet | Gigabit | not published |
| Form factor | USB-C docking hub | not published |
| Heat | Warm in use, which is normal for an aluminium hub | not published |
| Host requirement | The laptop's USB-C port must support DisplayPort Alt Mode; many budget laptops do not | not published |

| Plug | not published | Indian 2-pin |
| Power delivery | 85 W passthrough from a 100 W charger | not published |
| Technology | not published | Gallium nitride, which is why it is about half the size of a silicon 120 W charger |
| Three devices | not published | 65 W, 45 W and 10 W respectively |
| Total output | not published | 120 W shared across three ports -- not 120 W per port |
| Two devices | not published | USB-C 1 drops to 65 W and USB-C 2 takes 45 W. A laptop charging at 100 W silently halves when a phone is plugged in |
| Video output | 4K at 30 Hz only -- this is the specification that matters and the one buried in the manual | not published |
| Why 30 Hz | The hub shares one DisplayPort lane pair with data. 4K60 needs both pairs, which means no USB data | not published |
| Why this happens | not published | A shared power budget. Every multi-port charger does this and few publish the table |
