Baseus Docking Stations: Spacemate & UnionJoy Compared

By John Morris · Research checked September 16, 2026 · Our methodology

This collection contains two different Spacemate models and one UnionJoy model. Their largest power number, number of video sockets and product-family name answer different questions, so compare the exact host output and simultaneous display arrangement instead of treating them as interchangeable.

Choosing within Baseus

  • Spacemate 11-in-1 is the Windows-focused tower: The 11-in-1 Spacemate uses native USB-C MST and its current official diagram shows two HDMI plus two DisplayPort sockets, but the documented maximum is three external displays. It provides up to 85W to a compatible host from a separately purchased 100W input. On macOS, its dock-connected screens share one external desktop rather than becoming independent extensions.
  • RD1 Pro combines desk charging and dual displays: The Spacemate RD1 Pro adds a phone-charging surface and describes two external 4K60 displays on a suitable host. Its stated 100W laptop output sits within a shared 160W power budget; that total is not 160W delivered to the computer. It does not turn MST into two independent Mac desktops.
  • UnionJoy favors peripheral count, with power caveats: UnionJoy 17-in-1 provides seven USB connections and three video connector types for a peripheral-heavy desk. Its included 36W adapter powers the dock itself, not the laptop, and the current source does not resolve its host-charging output or every simultaneous display combination. Keep those facts unknown rather than borrowing the Spacemate specifications.

Baseus Spacemate RD1 Pro

RD1 Pro is aimed at a desk where the phone needs a home alongside the laptop. Its wireless charging surface and device-power connections are part of the attraction, so it makes sense to compare it with the dock-plus-phone-charger arrangement you would otherwise buy.

Baseus UnionJoy 17-in-1

UnionJoy earns a place in the comparison when a desk has accumulated more peripherals than a compact hub can conveniently accommodate. Its seven USB connections are the detail to inventory first: count the devices you leave attached before deciding whether a larger dock is worthwhile.
