Our take
Consider GN22B-GRAY if a USB-C notebook needs two USB-A ports, one USB-C data/Power Delivery connection and HDMI. The decisive compromise is that B&H lists HDMI up to 4K without a refresh rate and gives no PD wattage, so confirm the computer's video support and charging requirements before relying on it.
A USB-C notebook owner who needs two USB-A connections, a USB-C data/charging connection and HDMI, and can verify the host video capability and tolerate unspecified refresh rate and charging wattage..
It is not a documented fit for buyers who require Ethernet, SD or microSD readers, a confirmed HDMI refresh rate, a known charging wattage, or an exact current Amazon offer. B&H says Apple SuperDrive is unsupported.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- B&H identifies GN22B-GRAY and lists two USB-A 3.0 connections plus one USB-C 3.0/PD connection.
- HDMI up to 4K and data transfer up to 5Gbps are listed, without treating those ceilings as measured performance.
- The maker's retail record explicitly says Apple SuperDrive is unsupported, and the tagged model search avoids claiming the old ASIN is current.
What to weigh up
- The HDMI refresh rate and the USB-C PD wattage are not stated.
- The listed layout does not include Ethernet or card readers.
- The exact host fit and the current Amazon mapping of historic ASIN B01JQOSP84 are unverified.

Full review: how the features affect your choice
What the features mean for you
Does the port mix match a USB-C notebook?
GN22B-GRAY is a focused adapter for a notebook with a USB-C connection that needs ordinary USB-A peripherals plus one monitor. B&H names two USB-A 3.0 ports and a USB-C 3.0 port with Power Delivery, so compare those three USB connections with the devices already on the desk. The product record presents the USB-C connection as supporting charging, but does not give a wattage. Check the laptop's requirements and the power adapter you plan to use before treating this as a complete charging path. The connector shape alone does not prove that a computer supports every data, video and charging feature.
What does the HDMI listing establish?
B&H says the HDMI output supports content up to 4K, but does not state whether that resolution runs at 30Hz or 60Hz. The listing also does not spell out the host video mode required. Those omissions matter when a monitor's refresh rate is a must-have. Treat 4K as a resolution claim only, not a promise of a particular refresh rate, HDR, variable refresh or multiple external displays. Check the computer's USB-C or Thunderbolt video specifications and confirm the exact adapter revision before purchase.
Which other connections are documented?
The cited port map lists HDMI, two USB-A outputs and one USB-C output with PD. B&H does not list wired networking or SD and microSD access for this model. A buyer who regularly uses those connections would need separate adapters or should compare a hub whose own port list includes them. GN22B-GRAY is a better match when the main task is connecting a few USB devices and one display, rather than replacing a full desk dock with network and card expansion.
Will it work with the intended computer and accessories?
B&H describes a USB-C notebook hub and explicitly says Apple SuperDrive is unsupported. That limitation matters if the optical drive is part of the setup. The listing does not provide a compatibility matrix for every computer, operating system, monitor or high-draw peripheral. Verify that the computer's USB-C port supports the features you need, and check the exact model label rather than assuming another HyperDrive model has the same compatibility or port map.
How should you identify the right HyperDrive model?
HyperDrive has other USB-C hubs with different port layouts and display claims. The saved evidence here is tied to GN22B-GRAY; a listing that only says HyperDrive three-port may describe another unit. B&H identifies this model code, but its page says that this catalog item is no longer available there. That status applies to B&H and does not establish whether other sellers have current stock. Historic Amazon ASIN B01JQOSP84 has not been verified as a current exact variant, so use the tagged GN22B-GRAY search and check the item label, three USB connections and HDMI details on the selected offer.
What should you confirm before choosing it?
List the equipment that must attach: the monitor's resolution and refresh rate, the number of USB-A devices, whether a USB-C data connection is useful, and whether the laptop needs to receive power through the hub. GN22B-GRAY has evidence for three USB connections and one HDMI output, but its HDMI refresh rate and PD wattage are unknown. A short compatibility check makes those gaps visible before purchase. It also helps avoid choosing this model when wired networking or card reading is essential. This review uses the saved product specification and makes no hands-on test claim.
