Our take
HB037A is a conditional option when HDMI, card access, USB data, and PD pass-through are useful, but the buyer can confirm the exact USB layout on the offered unit. The listing identifies a model and several functions; its conflicting port fields and unverified dual-monitor wording limit how precisely this adapter can be matched. Treat the 4K/30Hz and 100W figures as listing claims.
A buyer who can compare the live port diagram and wants HDMI, card readers, and USB-C charging pass-through without requiring an exact USB count or confirmed dual-display behavior..
Do not choose HB037A when an exact number of USB-A or USB-C data ports, verified dual independent displays, 4K/60Hz, or a confirmed host charging wattage is a must-have.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Newegg identifies the model as HOPDAY HB037A and lists HDMI, SD/TF, PD, and USB data connections.
- The listing provides a 4K/30Hz HDMI claim and a 100W PD input claim that buyers can check against their needs.
- A tagged exact-model search is used because B0C23615W9 is not mapped to HB037A.
What to weigh up
- USB-A/C port counts conflict across the product's title and detail fields.
- The phrase dual monitor does not establish a second video output or simultaneous external screens.
- Host-delivered power, card concurrency, and the historical Amazon mapping remain unverified.

What the features mean for you
Which functions are named for HB037A?
The Newegg listing identifies model HB037A and describes a seven-in-one USB-C adapter with HDMI, USB data connections, PD, and SD/TF readers. This combination may suit a laptop or tablet that needs a display path, removable-card access, and some peripheral expansion in one small accessory. The product count is not a reliable port inventory by itself, however, because the USB-A and USB-C fields vary between the title and detail text. Before choosing the hub for a particular collection of devices, compare the live seller diagram with the exact ports you need. The model code helps narrow the search but does not resolve that conflict.
Does the dual-monitor wording establish two screens?
The product copy calls HB037A dual-monitor, but the saved port description consistently names one HDMI output and does not provide a verified second video connector or a simultaneous display matrix. The HDMI mode is advertised up to 4K at 30Hz. That is a listing specification, not a measured result, and the host computer must support video over its USB-C port. A buyer planning two extended screens should look for a port map and operating-system notes that document that arrangement directly. Do not count the marketing label as proof that two independent external displays work together.
What does the 100W PD figure tell a laptop owner?
HB037A's listing advertises a PD input up to 100W. It does not state a universal wattage delivered to the computer after the hub's own needs, the charger, cable, host negotiation, and connected devices are considered. Treat the number as a listed input ceiling rather than a laptop output guarantee. Confirm that the computer accepts USB-C charging on the relevant port, and check the charger's profile against the laptop's requirements. The PD connection is a charging function; its presence does not make the disputed downstream USB-C data count any clearer.
Can the SD and TF slots handle your media workflow?
The listing names both SD and TF, or microSD, reader functions. This supports a basic built-in card-access use case, but it does not establish the card generation, tested transfer rate, or whether the two readers operate at the same time. Buyers who ingest two card formats together or rely on a particular high-speed standard should verify the current unit and documentation before purchase. The adapter's HDMI and USB labels are not evidence of card-reader performance. Its strongest dependable distinction is that the listing names both formats while leaving their detailed behavior open.
How should you compare it with the separate HB033 model?
HOPDAY HB033 is a separate saved model with a more explicit six-function port list and two USB 3.0 data ports. The shared brand and similar USB-C hub category do not justify copying HB033's port details into HB037A. The latter's USB fields remain conflicting, and its “dual monitor” wording is not a verified port configuration. Compare model numbers, port-side photographs, and the exact connection list on the current offer. The historical ASIN B0C23615W9 has not been mapped to HB037A, so the affiliate link searches by model instead of asserting a direct product match.
Who can accept the remaining uncertainty?
HB037A may fit a buyer who needs the broad HDMI, charging, and card-reader functions and can inspect the exact USB map before ordering. It is not suitable as a precise match for a user who must have exactly two USB-A data ports, a downstream USB-C data socket, or simultaneous dual-display output. The model name provides a useful search target, but the current Amazon offer still needs checking. This assessment relies on the saved product listing and contains no personal test, buyer-review summary, current price, inventory, or sales claim.
What else to compare
Before you buy
How many USB data ports does HB037A have?
The listing fields conflict, so the exact USB-A/C counts remain unresolved; check the port diagram on the offered unit.
Does dual monitor mean two simultaneous external displays?
That is not established by the saved source, which documents one HDMI connector and no verified simultaneous mode.
Does 100W reach the laptop?
No such universal host output is stated; 100W is the listed PD input ceiling.
Is B0C23615W9 confirmed as HB037A?
No. The saved evidence does not map that historical ASIN to the model.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.
