Thunderbolt 5 docks have spent their first year priced like the laptops that need them. So the interesting thing about Engadget’s review of Keychron’s first dock isn’t the 8.3/10 — it’s that a keyboard company just shipped a genuinely sensible TB5 dock for $349, undercutting CalDigit and Anker’s $399 by fifty dollars while matching them where it counts. That’s the sound of a premium category turning into a normal one, and it’s worth understanding what you’re actually buying before the desk upgrade impulse takes over.
What Thunderbolt 5 actually buys you
TB5 is Intel’s latest shot at the one-cable desk: 80Gbps of symmetric data (with a 120Gbps boost mode when you need display bandwidth more than upload), enough power delivery to charge any laptop made this decade, and daisy-chaining that doesn’t fall over. In practice, the numbers that matter to a homelab desk are simpler:
- 140W upstream charging — one cable replaces the laptop brick permanently.
- 80Gbps — an external NVMe enclosure over TB5 stops being the slowest disk on the desk.
- Headroom — dual high-resolution displays and fast storage and networking at once, without the bandwidth arithmetic USB4 hubs make you do.
If your machine doesn’t have a TB5 (or at least TB4/USB4) port, none of this applies — a $60 USB-C hub is the honest answer, and no dock fixes a laptop that can’t take one.
Keychron’s port math
Fourteen ports, arranged the way someone who uses a desk would arrange them. Front: three 10Gbps USB 3.2 ports (two A, one C — I’d have preferred two C), full-size SD plus microSD slots where you can actually reach them, and a 3.5mm jack with a real audio interface inside, inline mic support included. Rear: three Thunderbolt 5 ports (one upstream, two downstream for SSDs or displays), two more USB-A, 2.5Gb Ethernet, a Kensington lock, and — the headline — two HDMI outputs.
The build is the quiet win. CNC-cut aluminium panels double as heatsinks, so it runs fanless and silent, and rubber feet on two sides let you stand it upright or lay it flat. Engadget’s reviewer notes you can insert a microSD card one-fingered without the dock sliding — a small thing that cheap docks reliably get wrong, and a tell that the manufacturer has actually used the product.
The catches that should shape your decision
No dock is perfect, and three of this one’s imperfections matter for our kind of desk:
- HDMI tops out at 4K/60. For higher resolution or refresh, you’re meant to use a Thunderbolt port for the display — which spends one of only two downstream TB5 ports. Dual HDMI is the differentiator, but it’s a 4K/60 differentiator.
- macOS multi-display quirk. macOS doesn’t natively drive multiple displays over a dock’s HDMI pair — both mirror. Mac users get one HDMI plus one TB display and change; Windows handles dual HDMI fine. Check your OS before the port count sells you.
- 2.5GbE, not 10GbE. For a homelab desk where the storage network is the point, this is the real miss. If your switch is 10G and your NAS is 10G, the dock’s Ethernet becomes your bottleneck the day you plug in.
No internal SSD bay, either — Razer’s $379 Chroma has one — though that’s a convenience trade rather than a capability one, given the downstream TB5 ports.
The field at $350
Every rival is a variation on the same theme: CalDigit’s TS5 ($399) is the incumbent favourite but drops HDMI entirely; Razer’s TB5 Chroma ($379) adds the SSD bay and RGB, also no HDMI; Anker’s Prime TB5 ($399) matches Keychron’s spread but swaps the second HDMI for DisplayPort and hides the SD slots on the side. Keychron’s dual-HDMI-plus-front-cards combo is genuinely the most desk-practical arrangement of the lot, and it’s the cheapest of them. Whoever thought the keyboard company would be the one shipping “boring and correct”?
Should a homelab buy it?
My checklist, having watched this category for a while:
- Yes if you run a TB5/TB4 laptop as your main machine and want the one-cable desk: power, dual 4K displays, storage, and Ethernet from a single plug, fanless, $349.
- Yes if you juggle a laptop and a desktop at the same desk — one dock, two computers, standardised cabling.
- Wait if your LAN is 10G today or planned — 2.5GbE is the dock’s weakest port, and it’s the one a homelab actually stresses.
- Wait if you’re on macOS and want two dock-driven displays; the mirroring quirk takes the headline feature off the table.
The bigger picture is the one I’d bank: this is the second piece of desk infrastructure in a month where the budget option stopped meaning compromise. First universal docks made us the QA team; now the good stuff is getting cheap enough to be the default recommendation. Buy when the specific port map matches your desk, not when the discount does.
