THE SHORT ANSWER

Our take

JCD372S is a compact USB-C adapter with a clear official port description: two USB-A Gen 2 connections, SD/microSD reading and one HDMI output up to 4K/30Hz. j5create positions it for Surface Pro 8 and requires host DisplayPort Alt Mode. It is a good candidate when those roles fit, but the specification lists bus power and no PD input, so it should not be treated as a charging dock.

Consider it for

A Surface Pro 8 owner or compatible USB-C host user seeking USB-A, SD/microSD and one 4K/30Hz display connection without host charging pass-through..

Look elsewhere if

Avoid it if you require 4K/60Hz, laptop charging through the hub, a host without USB-C DisplayPort Alt Mode, a longer cable, or proof that the historical Amazon ASIN is the exact current JCD372S offer.

Full review: how the features affect your choice

What the features mean for you

Add useful ports beside a Surface Pro 8

j5create presents JCD372S as a USB-C multi-adapter for Surface Pro 8. It adds two USB-A connections, HDMI and a combined SD/microSD reader in a short attached-cable format. That can fit a tablet-style computer used at a desk with a monitor, a flash drive and memory cards. The official product page is model-specific, which is more useful than relying on a broad frozen title that also names Surface Pro 9, MacBook, XPS and HP systems. Confirm connector clearance and the exact host's supported modes before buying.

Confirm DisplayPort Alt Mode on the host

The hardware specification requires USB-C DisplayPort Alt Mode for HDMI. A port's USB-C shape alone does not guarantee video output; the computer must support the needed signal. j5create lists one display up to 3840 by 2160 at 30Hz. If your monitor setup depends on 4K/60Hz or more than one external display, this is not the claim the saved specification makes. Check the laptop or tablet manual and match the required output mode rather than interpreting the generic phrase 4K HDMI as a refresh-rate guarantee.

Use the USB-A speeds as interface claims

The two Type-A ports are listed as USB 3.2 Gen 2 with data up to 10Gbps. This identifies the interface class for attaching compatible drives and accessories, but it does not promise a 10Gbps file copy. The connected device, host controller and workload affect real performance. With two storage devices active at once, the host's link and shared adapter path can further limit results. The product evidence does not provide a simultaneous throughput test, so treat the number as an advertised maximum rather than a measured speed in a real setup.

A card reader for both common formats

The official specification lists an SD/microSD 3.0 UHS-I reader. This is useful when a user transfers photos or files from cards without carrying a separate reader. Confirm that the card type and the desired workflow are supported by the current manual; the saved record does not establish specific capacity limits or the speed of a particular card. If both slots are needed at once, the exact simultaneous operation should be checked in the full documentation rather than inferred from a combined reader line.

Do not expect it to charge the computer

j5create describes JCD372S as bus-powered and does not list a Power Delivery input. The adapter therefore adds ports but does not replace the computer's charging cable. Buyers who need a single-cable desk setup with laptop power should compare another model with a documented PD input and check its delivered-power rating. The saved source also lists a 200mm cable, which is intentionally short; it may sit neatly beside a tablet yet fall short if the laptop is positioned far from its monitor or accessories.

Check the exact offer and host scope

The official page names model JCD372S and Surface Pro 8, while the older source-row title lists several additional computer families. That broader fit list is not established by the model page inspected here. The historic B0BTYFJ78Z page was not readable and has not been mapped to a current exact offer. Search by JCD372S, inspect the adapter's model text and verify the exact host, display and card requirements.
