A $229.99 USB-C dock that pairs the laptop's own video output with DisplayLink to give it three extended 4K screens, and the maker's own warning that games, full-screen video and video editing may not work through it.
A $39.99 GaN brick that gives one laptop 65 W and, with three devices attached, hands the other two 8.5 W apiece. Good at its main job, modest at the second and third.
A $39.99 seven-port hub with HDMI at 4K and 30 Hz, two 5 Gbps USB-A ports, SD and microSD slots and 85 W pass-through. Anker now sells a newer 7-in-1 for $25.99 with 4K at 60 Hz, which changes what the 341 is worth.
A $19.99 braided cable certified for 240 W Power Delivery. Its data line is USB 2.0 and it cannot carry video, so the number on the label only matters if you own something that draws it.
