A docking hub that drives three external HDMI displays from a single laptop, with an RGB-lit cooling fan keeping things from overheating during long sessions.
If your workflow genuinely needs four displays running at once — your laptop plus three externals — the H1 is a specialized tool for exactly that. The catch is the resolution ceiling: 1920x1080 at 60Hz per HDMI output is fine for spreadsheets, chat windows and reference material, but it's not going to satisfy anyone wanting crisp 4K across all four screens. This model also showed as sold out on Kwumsy's site during our research.
The H1 packs three HDMI video outputs and three USB connections (USB-A and Type-C) into a single hub, aimed at people who need to manage several task windows across multiple screens without buying a full docking station. An RGB-lit cooling fan keeps operating temperature under control — Kwumsy claims under 95°F operation and under 15dB of fan noise, which would be quiet enough not to notice in most office settings.
Three simultaneous HDMI outputs let you build a genuine four-screen setup (laptop plus three externals), though each is capped at 1080p60 rather than higher resolutions.
Beyond video, the hub carries three 5Gbps USB-A ports, a USB-C power delivery input and a second USB-C port, plus a TF card slot for quick file transfers.
Running three video outputs and multiple USB connections generates heat, so Kwumsy built in an active cooling fan rated under 15dB — quiet enough to avoid becoming a distraction at a desk.
Kwumsy lists support for macOS (including Apple M1/M2/M3 chips), Windows and Android, though a driver install is required to get all outputs working correctly.

The H1 isn't for casual users — it's for people who genuinely need three extra 1080p displays running from one laptop port. If that's your workflow, the resolution cap is an acceptable trade-off for the convenience of a single hub.
