Head-to-head
Plugable TBT-UDH2 vs Anker Prime Thunderbolt 5: UDH2 keeps two HDMI cables, Anker removes the power brick
The short answer
TBT-UDH2 keeps two HDMI cables connected directly, while Anker removes the separate power brick. Choose UDH2 for two supported HDMI monitors and a TB drive, or a compatible TB accessory that needs more than 15W. Choose Anker when a single fixed HDMI or DP connection plus a TB screen route fits the desk and integrated power is the priority. Anker’s HDMI and DP cannot run together. UDH2 excludes TB3, USB-C-only, Windows ARM and the specified DP-MUX gaming hosts.
Before you choose
The reasoning and the trade-offs
Count the second HDMI connection before choosing the tidier box
A desk with two HDMI monitors and a Thunderbolt drive uses UDH2’s two fixed outputs plus its one downstream TB port. Anker’s HDMI and DP sockets cannot operate together, so its DP socket is not a second simultaneous fixed-screen answer. The second HDMI monitor needs a compatible TB-to-HDMI connection, leaving the other TB port for the drive. Both can fit the arrangement on a supported host, but Anker adds a video adapter or cable where UDH2 keeps the existing HDMI cables. Anker may still be preferable if removing the separate power brick solves the larger placement problem. The useful comparison includes the adapter and supply around each dock.
What this is based on
Two HDMI screens plus one TB-only drive mapped onto the exact available routes. Anker simultaneous fixed-video restriction retained. No universal adapter-mode compatibility or unsupported screen count.
Main trade-off
Anker Prime Thunderbolt 5 A83B5
HDMI and DP cannot be active together. Two HDMI monitors need another compatible video route, and TB accessory power is limited to 15W per port.

About this comparison
TBT-UDH2 vs Anker A83B5 for dual HDMI screens, a portable monitor and camera imports. Check the adapter, power and host limits that change the setup.
Both are premium TB5 desk docks with 140W host charging and 2.5GbE. They offer different ways to connect a similar two-screen home office, rather than targeting unrelated mobile and desktop jobs.

What matters in practice
The differences that matter
Count the second HDMI connection before choosing the tidier box
A desk with two HDMI monitors and a Thunderbolt drive uses UDH2’s two fixed outputs plus its one downstream TB port. Anker’s HDMI and DP sockets cannot operate together, so its DP socket is not a second simultaneous fixed-screen answer. The second HDMI monitor needs a compatible TB-to-HDMI connection, leaving the other TB port for the drive. Both can fit the arrangement on a supported host, but Anker adds a video adapter or cable where UDH2 keeps the existing HDMI cables. Anker may still be preferable if removing the separate power brick solves the larger placement problem. The useful comparison includes the adapter and supply around each dock.
How we reached this conclusion
Two HDMI screens plus one TB-only drive mapped onto the exact available routes. Anker simultaneous fixed-video restriction retained. No universal adapter-mode compatibility or unsupported screen count.
Two USB-C screens reverse the recommendation, unless storage needs a branch too
If both monitors depend on USB-C or Thunderbolt, Anker can give each a direct downstream branch. UDH2 has only one. That makes Anker easier for this screen arrangement despite having fewer usable fixed outputs. Add a Thunderbolt-only backup drive, however, and both Anker branches are occupied. The drive then needs a suitable host port, chain or a different screen input. UDH2 may become viable if the monitors also accept HDMI, because moving both screens to HDMI frees its TB port for the drive. This is why the screens, storage and usable input alternatives should be planned together instead of choosing by the number of video sockets.
How we reached this conclusion
Two direct USB-C displays exhaust Anker’s two TB branches, while UDH2 has one. Optional HDMI inputs change topology. No assumption that every monitor supports a reverse adapter or every TB chain works.
Camera imports can add a second accessory just as the desk fills up
A parent or hobbyist may import camera footage at the same desk used for work calls and charging a phone. UDH2’s UHS-II readers can keep a compatible fast-card workflow inside the dock. Anker’s UHS-I readers may leave an external UHS-II reader in the arrangement if that higher interface capability matters. The difference disappears with a UHS-I card or a destination drive that is already the limiting part of the transfer. UDH2 also supplies up to 30W from its TB accessory port, compared with Anker’s 15W per TB port, which can matter for an explicitly compatible powered peripheral. These are separate workflow checks, not proof that UDH2 imports files faster in every setup.
How we reached this conclusion
Built-in UHS classes crossed with an already busy desk. Reader capability is conditional on card and destination. Exact downstream power maxima are distinct from host power and do not establish peripheral compatibility alone.

Meaningful differences
What changes the fit
| What changes | Plugable TBT-UDH2 | Anker Prime Thunderbolt 5 A83B5 | Why it matters |
|---|---|---|---|
| Two HDMI monitors | Two direct HDMI 2.1 outputs | One HDMI output, alternative to DP | Anker needs a supported TB video route for the second HDMI screen. |
| Downstream TB | One TB5 port, up to 30W | Two TB5 ports, up to 15W each | Two USB-C screens favor Anker’s branch count, while a higher-power accessory can favor UDH2. |
| Card import | UHS-II SD and microSD | UHS-I SD and microSD | The camera card and destination drive decide whether this difference matters. |
| Power supply | Separate supply | Integrated supply | Both offer up to 140W host power. The desk-placement problem differs. |
| Network | 2.5GbE | 2.5GbE | Neither removes a slower switch or NAS bottleneck. |
| Host support | Supported TB5/TB4/USB4, with explicit ARM and DP-MUX exclusions | Supported TB5/TB4/USB4, not TB3 | Check the exact host and OS rather than relying on the socket shape. |
What you give up
Every choice has a cost
If you choose Plugable TBT-UDH2
- Two USB-C-only monitors cannot both connect directly through its single TB branch. A reverse HDMI cable should not be assumed to solve that.
If you choose Anker Prime Thunderbolt 5 A83B5
- A second HDMI screen needs a compatible TB-to-HDMI connection. Its card readers are UHS-I, so a UHS-II import workflow may retain another reader.
Recommendation switch
The decision flips if...
The actual setup uses two HDMI screens and fast camera cards
Choose Plugable TBT-UDH2. UDH2 can keep both jobs inside the intended connections.
Two USB-C screens or integrated power matter more than the direct HDMI pair
Choose Anker Prime Thunderbolt 5 A83B5. Anker’s layout can suit that desk, with storage and power limits checked.
What matters in practice
Before you choose
You want fewer pieces around the desk without paying for a tidy dock that needs another adapter every time the second screen is used.
What this comparison cannot tell you
- No measured transfer, frame-rate, charging-time or noise advantage. Host-specific native display limits still apply. Neither dock is treated as a hardware KVM.
