Our take
JP-HUB-83 is a multi-display USB-C dock whose key distinction is three video connectors alongside explicit host and operating-system caveats. Amazon maps B08B3NV1BY to MOKiN model UC0304 and part JP-HUB-83. Its associated manual record describes two HDMI outputs, one DisplayPort, one faster USB-A port, two USB 2.0 ports, two card slots, and an 87W charging-output limit. Choose it around the host's display behavior, not socket count alone.
A buyer comparing several monitor connectors for a compatible USB-C laptop who checks OS behavior and accepts that two USB-A ports are USB 2.0..
Do not choose it expecting three independent extended displays on macOS, three fast USB-A ports, or 100W of guaranteed laptop output.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Amazon Item Details directly associate the ASIN, brand, model, and part number.
- The manual record describes two HDMI ports, DisplayPort, and simultaneous SD/microSD reading.
- It distinguishes 100W PD input from up to 87W charging output.
What to weigh up
- macOS instructions describe additional displays as mirroring rather than separate desktops.
- Only one of three USB-A data ports is listed as USB 3.0.
- The host must support USB-C data, video, and PD for those functions.

Full review: how the features affect your choice
What the features mean for you
Choose by the operating system's display behavior
The manual record lists two HDMI connectors and one DisplayPort, but describes different multi-monitor behavior by operating system. It says Windows MST can extend across three external displays, while macOS can extend to one external display and mirror additional displays. This difference matters more than the socket count to someone who needs separate workspaces. Confirm the laptop's display support and OS requirements before planning a multi-screen desk. These are product-manual claims, not independent tests across every computer model.
Match the USB-A ports to the devices
The manual lists one USB 3.0 port up to 5Gbps and two USB 2.0 ports up to 480Mbps. That mix can handle a keyboard, mouse, printer, and one faster external storage device, but it is not three equivalent high-speed ports. Reserve the faster socket for the device that benefits most from its higher interface ceiling. These are listed link capabilities, not measured copy speeds; actual transfers depend on the host, attached device, and simultaneous traffic.
Use the two card formats deliberately
The manual record describes SD and TF slots that can read cards at the same time. This can simplify a workflow that moves files from a full-size camera card and a microSD card without swapping readers. The source does not establish real-world transfer rates for a particular card, so treat speed figures as specifications rather than a test result. If card capacity, file system, or UHS behavior matters, check the card and current documentation against the exact use case.
Check USB-C host capabilities before buying
The record says the laptop's USB-C port must support Power Delivery, DisplayPort Alt Mode, and USB data for the corresponding dock functions. The physical connector alone does not establish video or charging support. Check the computer's official port specification and compare the OS notes with the intended display setup. The manual also lists device-specific compatibility limits, so do not assume that every older laptop, phone, or tablet with USB-C will use all three monitor connectors. An exact listing does not make host support universal.
Separate charging input from the output limit
The manual states 100W PD input and up to 87W charging output. Those are different sides of the power path: 100W is what the dock accepts from a charger, while 87W is the documented maximum output for charging the laptop. Neither guarantees the result for every host or load. Compare the computer's power requirement with the hub, charger, and cable. Attribute the figures to the manual record rather than presenting them as measured laptop charging under load.
Keep this MOKiN model distinct
Amazon Item Details identify B08B3NV1BY as MOKiN, model UC0304, and part JP-HUB-83. MOKiN also has other multiport products, including MOUC0313, which is a different SKU and is not merged here. The exact listing is linked with the affiliate tag because the model crosswalk is recorded. Compare the current product photos and part number before ordering. This assessment uses no price, stock claim, buyer-review summary, or hands-on result.
