Quick Answer
For a clean cable-managed setup, buy the dock in this order: first a single-cable USB-C dock with enough power delivery for your laptop (look for 85W-100W PD), then the right display outputs, then extra USB and card slots last. A R1,800-R3,500 dock that delivers 100W and drives two monitors replaces five cables with one, which is the whole point of cable management.
Must-Have: One Cable, Enough Power
The dock's job is to collapse your charger, monitor, keyboard, mouse and Ethernet into one USB-C cable. The make-or-break spec is power delivery: a thin-and-light laptop needs 65W, a 15-inch workstation wants 85-100W. Underpowered docks (45W) leave the battery slowly draining while plugged in. Confirm the PD figure before anything else; a R2,000 100W dock beats a R1,400 dock that cannot charge your machine.
Next: Display Outputs That Match Your Monitors
Decide your monitor layout before buying. A single 4K 60Hz screen needs one HDMI 2.0 or DP 1.4 output; dual 1440p needs a dock that explicitly supports two displays at your refresh. Many cheap docks mirror rather than extend on USB-C-only laptops, so check that yours supports DisplayPort Alt Mode. For a 144Hz panel, verify the dock and cable carry the bandwidth, not just '4K supported'.
Skip Last: Extra Ports You Will Not Use
Card readers, optical audio and a sixth USB-A port are nice-to-haves that inflate the price. Buy them only if your workflow needs them today. A photographer wants the SD reader; a coder does not. Spend the dock budget on PD and display bandwidth first, then add port count only if there is money left.
FAQ
What power delivery does a laptop dock need?
Match it to your laptop: 65W for a thin-and-light, 85-100W for a 15-inch workstation. An underpowered 45W dock drains the battery slowly even while plugged in.
Can one dock drive two monitors cleanly?
Yes, if it explicitly supports dual displays at your resolution and refresh and your laptop supports DisplayPort Alt Mode. Confirm '2x 1440p' or '2x 4K', not just '4K supported'.
How much should a good single-cable dock cost in SA?
Around R1,800-R3,500 buys a dock with 85-100W PD and dual-display output, which is the spec floor for genuine one-cable desk tidiness.
dock's power-delivery wattage matches your laptop and that it lists dual-display support at your exact refresh rate before you buy; everything else is secondary.
