Our take
USBC-MD103 is a focused three-function adapter, but the manufacturer does not give one consistent HDMI refresh-rate or PD wattage statement across the saved materials. Match the exact current revision to the display and charging needs.
A USB-C laptop user who needs one display, one USB-A peripheral, and a power pass-through connection and can verify the current revision's video and wattage limits..
Avoid relying on a guaranteed 4K60 mode or 100W pass-through unless the exact current hardware revision confirms those figures.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Plugable identifies USBC-MD103 and its USB-C host, HDMI, USB-A, and PD functions.
- The one USB-A port is listed at up to 5Gbps.
- The current product page states that a charger is not included.
What to weigh up
- Manufacturer sources conflict between 4K30 and 4K60 HDMI claims.
- PD pass-through is described as 60W in an older announcement and up to 100W on the current page.
- The historical ASIN is not connected to a hardware revision.

Full review: how the features affect your choice
What the features mean for you
Add the ports that are missing from a compatible USB-C laptop
USBC-MD103 is a compact adapter for three basic jobs: connect one HDMI display, add one USB-A data port, and pass power through USB-C. This is a more focused option than a large desk dock with Ethernet or card readers. It may suit a user carrying a laptop that needs a wired peripheral and one screen while keeping a charger connection available. The host still needs a full-featured USB-C port with the relevant display and charging support; a USB-C-shaped connector alone does not prove that the laptop can use video output.
Resolve the 4K refresh-rate conflict
Plugable's current page does not present one consistent HDMI ceiling. Its feature bullets and specification table include 4K60, while a nearby explanatory paragraph says 4K30. Plugable's older announcement for the same USBC-MD103 SKU also says 4K30. Because those are manufacturer sources tied to the same model name, this profile preserves the disagreement rather than picking the more attractive number. If refresh rate matters for a monitor or projector, check the hardware revision and written resolution table for the exact item before buying.
Confirm how much charging reaches the computer
The current page advertises up to 100W USB-C pass-through and says the power adapter is not included. The older announcement gives a 60W maximum. The exact historical Amazon ASIN B08CL4Y3PJ has not been tied to a revision that resolves the discrepancy. A buyer should check the product label, revision, or current manufacturer specification and verify the charger and cable too. Do not assume the laptop will receive 100W simply because a current page headline says that is the maximum.
Expect one downstream USB-A connection
The detailed current page identifies one USB-A 3.0 port at up to 5Gbps. That can be enough for a single flash drive, mouse, or similar peripheral, but it does not replace a multiport USB hub. It is backward-compatible with USB 2.0 devices according to the page. There is no Ethernet, card reader, or additional downstream USB-A output listed for this model, so someone with several peripherals may need a separate hub.
Match the exact manufacturer SKU, not just three-in-one
Plugable's official page identifies the model as USBC-MD103, while the historical Amazon listing is not verified against a current revision. Search by the manufacturer SKU and compare the official port face and revision before relying on the video or PD rating. The product page offers current retailer links, but the product match for the old ASIN was not established here. This review is specification-based and does not summarize consumer feedback or claim personal testing.
Check the host capability and charger as a pair
The adapter's USB-C plug does not itself guarantee the laptop's video mode or charge rate. Plugable says a full-featured USB-C, USB4, or Thunderbolt host is needed for the listed functions, while the product page and older announcement disagree on the adapter's maximum pass-through rating. Confirm the computer's own USB-C capabilities and the precise adapter revision, then use a suitable charger and cable. This matters most when the adapter is expected to support a work monitor while maintaining laptop charge; neither the connector shape nor the higher current-page figure resolves both requirements.
