The catch
Plugable TBT-UDH2
It has one downstream TB port and a separate power supply. Check its explicit host exclusions against every work or gaming laptop.
Side by side
Two HDMI cables connect directly on the TBT-UDH2, and the Anker gets rid of the separate power brick. If you have two supported HDMI monitors and a TB drive, or a compatible TB accessory that needs more than 15W, the UDH2 is the pick. If a single fixed HDMI or DP connection plus a TB screen route suits your desk and built-in power matters most, go with the Anker. HDMI and DP on the Anker cannot be used together. The UDH2 does not support TB3, USB-C-only or Windows ARM hosts, or the specified DP-MUX gaming hosts.
Before you buy
For two HDMI monitors and a Thunderbolt drive, UDH2 uses its two fixed outputs and its single downstream TB port. Anker’s HDMI and DP sockets cannot run together, so its DP socket does not give you a second fixed screen at the same time. The second HDMI monitor has to go through a compatible TB-to-HDMI connection, which leaves the other TB port for the drive. On a supported host either dock can handle this desk, but Anker adds a video adapter or cable where UDH2 lets you keep the HDMI cables you already have. Anker can still come out ahead if getting rid of the separate power brick fixes the bigger placement problem. Compare the docks together with the adapter and power supply each one needs.
Where this comes from
Two HDMI screens and one TB-only drive are matched to the exact routes available. Anker’s restriction on simultaneous fixed video stays in place. No claim is made of universal adapter-mode compatibility or an unsupported screen count.
The catch

The catch
HDMI and DP cannot be active at the same time. Two HDMI monitors need another compatible video route, and TB accessory power is capped at 15W per port.

TBT-UDH2 vs Anker A83B5 for dual HDMI screens, a portable monitor and camera imports. Look at the adapter, power and host limits that can change how the setup works.
Each is a premium TB5 desk dock with 140W host charging and 2.5GbE. They take different approaches to wiring a similar two-screen home office, and they do not aim at unrelated mobile and desktop jobs.
Which one fits
Anker needs a compatible TB route for the second HDMI screen.
Anker has two TB branches, and the host has to support both screens.
That interface capability is not something Anker’s UHS-I readers provide.
Anker has the supply built in, but do not read that as a noise or heat advantage.

Two HDMI screens and one TB-only drive are matched to the exact routes available. Anker’s restriction on simultaneous fixed video stays in place. No claim is made of universal adapter-mode compatibility or an unsupported screen count.
When both monitors rely on USB-C or Thunderbolt, Anker can give each one a direct downstream branch, while UDH2 has only one. For that screen arrangement Anker is the easier fit, even though it has fewer usable fixed outputs. Once you add a Thunderbolt-only backup drive, though, both Anker branches are taken. The drive then needs a suitable host port, a chain or a different screen input. If the monitors also accept HDMI, UDH2 can work after all, because moving both screens to HDMI frees its TB port for the drive. That is why you should plan the screens, the storage and the usable input alternatives together instead of choosing by the count of video sockets.
Two direct USB-C displays use up both of Anker’s TB branches, and UDH2 has one. Optional HDMI inputs change the topology. It is not assumed that every monitor supports a reverse adapter or that every TB chain works.
A parent or hobbyist might import camera footage at the same desk that handles work calls and phone charging. With UDH2’s UHS-II readers, a compatible fast-card workflow can stay inside the dock. Anker’s UHS-I readers may leave an external UHS-II reader in the picture if that higher interface capability matters to you. The gap vanishes with a UHS-I card, or when the destination drive is already the limiting part of the transfer. UDH2 also supplies up to 30W from its TB accessory port, against Anker’s 15W per TB port, which can count for an explicitly compatible powered peripheral. Treat these as separate workflow checks and not as proof that UDH2 imports files faster in every setup.
Built-in UHS classes are weighed against a desk that is already busy. Reader capability depends on the card and the destination. The exact downstream power maximums are separate from host power and do not on their own establish peripheral compatibility.

Plugable, TBT-UDH2
Your two HDMI screens can stay on their current cables, and the downstream TB port is still free for a drive.

Anker, A83B5
Built-in power gets rid of an awkward separate adapter, and a single direct fixed video output is enough for what you have planned.
Spec by spec
| Spec | Plugable TBT-UDH2 | Anker Prime Thunderbolt 5 A83B5 | In practice |
|---|---|---|---|
| Two HDMI monitors | Two direct HDMI 2.1 outputs | One HDMI output, alternative to DP | Anker has to use a supported TB video route to reach the second HDMI screen. |
| Downstream TB | One TB5 port, up to 30W | Two TB5 ports, up to 15W each | Anker’s branch count suits two USB-C screens, but an accessory that needs more power can tip things toward UDH2. |
| Card import | UHS-II SD and microSD | UHS-I SD and microSD | Whether this difference matters comes down to the camera card and the destination drive. |
| Power supply | Separate supply | Integrated supply | Either dock offers up to 140W of host power. What differs is the desk-placement problem. |
| Network | 2.5GbE | 2.5GbE | A slow switch or NAS bottleneck stays in place with either dock. |
| Host support | Supported TB5/TB4/USB4, with explicit ARM and DP-MUX exclusions | Supported TB5/TB4/USB4 (TB3 unsupported) | Go by the exact host and OS. The shape of the socket does not settle it. |
Trade-offs
Change of plan
Go with Plugable TBT-UDH2. UDH2 can handle both jobs within the connections intended for them.
Go with Anker Prime Thunderbolt 5 A83B5. Anker’s layout can suit that desk once storage and power limits have been checked.
Decision guide
Fewer things around the desk is the goal, but a tidy dock is not worth paying for if every use of the second screen needs another adapter.
