Our take
HB-MC3G is a straightforward four-port USB-A data hub with a detachable 30-inch cable and a 900mA combined current limit. Choose it for low-draw peripherals and verify the current model listing; it is not a charging station.
A desktop user needing four USB-A data ports, a detachable longer host cable, and a metal hub for low-draw peripherals rather than device charging..
Someone who needs USB-C, HDMI, Ethernet, per-port charging, high-current bus-powered storage, or an exact Amazon product link.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- B&H confirms four USB-A Gen 1 ports and the exact HB-MC3G model.
- A detachable 30-inch host cable and metal housing help with desktop placement.
- Backward compatibility with USB 2.0 and 1.1 devices is listed.
What to weigh up
- The combined current limit is 900mA and demanding drives need their own power.
- The hub syncs data but does not charge attached devices.
- B&H marks its offer unavailable and Amazon's detail page was unreadable.

Full review: how the features affect your choice
What the features mean for you
Count four SuperSpeed sockets plus a separate host connection
HB-MC3G adds four downstream USB-A 3.0/3.1 Gen 1 ports to a computer through a separate upstream cable. B&H specifies a detachable 30-inch Type-A-to-Micro-B cable, which gives more placement flexibility than a hub that must sit directly against a computer port. Check the host side carefully: this is not a USB-C dock and does not add HDMI, Ethernet, or card readers. It is a straightforward way to attach ordinary USB-A data devices to a compatible computer, with a gold finish intended to coordinate with silver or gold desktop hardware.
Match the 5Gbps ceiling to the actual workload
The USB 3.0/3.1 Gen 1 ports are listed for data transfer up to 5Gbps. That is an interface maximum, not a guarantee of real copy speed. The host port, cable, connected drive, file mix, and concurrent activity all affect throughput. The B&H page also lists USB 2.0 and 1.1 backward compatibility, which can keep older input devices or peripherals connected, but those devices retain their own lower interface limits. For routine keyboards, mice, and flash storage, this is a clear port expansion; buyers with faster SSD workflows should compare the hub's Gen 1 ceiling with a 10Gbps or 20Gbps alternative.
Keep total power modest and supply demanding drives separately
B&H states a combined current limit of 5V/900mA for attached devices and recommends an external power source for hard drives. The hub can sync data but is not a charging station. That makes it a better fit for low-draw accessories than for several bus-powered storage devices or charging phones. The available page does not describe an external adapter input on this model, so do not assume one can be added to raise the budget. Use self-powered drives as directed and compare each peripheral's requirements before connecting a group of devices.
Account for the single faster-generation design and older device support
Four sockets share one USB 3.0 Gen 1 hub design. B&H advises that a 2.4GHz wireless keyboard or mouse receiver may work better in a USB 2.0 port away from the USB 3 hub. Since this model's downstream sockets are USB 3.0, a practical workaround is to connect the receiver directly to a host USB 2.0 port if available or use a short extension to move it away. This is a source warning rather than a claim that every receiver will fail. Wired devices and many USB 2.0/1.1 peripherals remain compatible according to the listing.
Use the metal body and cable length to plan a tidy layout
The model-specific page describes an aluminum shell and rubber bottom, with a detachable 30-inch host cable. The rubber base is intended to stabilize the hub, while the separate cable can help place it where four plugs can be reached. The page lists weight at 2.5 ounces. It does not describe per-port switches or LEDs, so do not expect to turn off each attached device from the hub. If you want individual power controls, search for another Sabrent model with those features; a similar brand name does not make HB-MC3G and a switched hub the same product.
Confirm availability and exact code before buying a remaining offer
The model itself is well-documented by B&H, and an importer ties the historical ASIN to the gold HB-MC3G. B&H's page now says its offer is no longer available there, while Amazon did not return a current detail page. Use the tagged model search and confirm the listing shows HB-MC3G, four USB 3.0 ports, and a 30-inch detachable host cable. Avoid substituting HB-MC3B or another four-port Sabrent model without comparing the color and cable.
