Our take
Choose HB-MAC3 as a straightforward four-port USB 3.0 data hub for a computer with a USB-A host connection. Its limits are equally simple: no documented display, Ethernet, card-reading, or host-charging features, and high-draw devices may need their own power.
A computer with a USB-A host port that needs four data connections for peripherals and does not need video, Ethernet, or host charging..
Skip it if your only host port is USB-C, if the main task is charging devices, or if you need a monitor or wired network connection.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Sabrent identifies the HB-MAC3 model and four USB 3.0 downstream ports.
- B&H lists a USB-A host, 30-inch cable, aluminum enclosure, and bus-powered operation.
- The manufacturer claims Windows, Mac, and Linux compatibility and backward compatibility with older USB devices.
What to weigh up
- B&H describes this as a data-sync hub rather than a charger for attached devices.
- No per-port current budget or separate adapter is documented; external drives may require their own power.
- The historical Amazon ASIN is not confirmed as HB-MAC3, so use a tagged model search.

Full review: how the features affect your choice
What the features mean for you
Four additional USB-A connections for a computer with a USB-A host port
The HB-MAC3 is a straightforward four-port USB 3.0 hub. Sabrent's official page identifies the model and describes four added USB 3.0 ports, while B&H lists its host connection as USB-A and the cable as 30 inches. That makes the model most relevant to a desktop or laptop with a compatible USB-A port and several wired accessories. It is not a USB-C multiport adapter: no HDMI, Ethernet, card reader, or USB-C charging input appears in the documented port map. Check the connector at the computer before ordering, especially if the only available host connection is USB-C.
Plan around USB data rather than device charging
Sabrent lists a USB 3.0 transfer ceiling of 5Gbps, with backward compatibility for USB 2.0 and USB 1.1 devices. Those are interface rates, not expected file-copy benchmarks. The attached computer, cable, device, and concurrent traffic all affect real throughput. B&H describes this model as a data-sync hub rather than a charger and advises using separate power for external hard drives. It is therefore a poor choice if the main goal is to charge phones or run several power-hungry drives from the hub. The sources do not give a detailed per-port current budget, so do not infer one from the four-port count.
A simple setup with limits for high-draw peripherals
Sabrent describes plug-and-play and hot-plug use and claims compatibility with Windows, Mac, and Linux. The model page lists a USB 3.0 cable, while the retailer specification records a 30-inch cable. The sources do not identify a separate wall adapter or describe this as an externally powered hub. For storage devices that need more power than a bus-powered hub can provide, follow the drive maker's separate-power requirement. For low-power peripherals such as a keyboard, mouse, or printer, this four-port data expansion can reduce repeated cable swapping, subject to the computer's own USB limits.
Keep the model separate from other Sabrent hubs
Sabrent sells multiple USB hubs with similar four-port descriptions and different model codes. HB-MAC3 is the specific silver aluminum model documented by the official product page; the historical ASIN was not associated with that page during the saved review. Use the tagged model search to inspect the selected result, then compare the HB-MAC3 marking, host connection, and port count. The old ASIN is not used as a direct product link. This assessment relies on manufacturer and retailer specifications only, without personal testing, buyer-review summaries, current price, stock, or sales claims.
Check the cable route and power needs at the desk
The 30-inch cable gives some placement flexibility, but the reviewed sources do not establish a mount or a powered charging station. Decide whether a roughly 76-centimeter reach places the four ports where they are useful, and leave room for any hard drive that needs its own adapter. The four-port count is a connection convenience, not evidence that all attached devices can draw unlimited current or reach independent 5Gbps speeds at once. If those conditions matter, check the computer's USB limits and the drive specifications before choosing this model.

Before you buy
How many downstream USB-A data ports are listed?
Sabrent lists four downstream USB 3.0 USB-A data ports.
Does the source support 5Gbps?
Sabrent lists that maximum interface rate for USB 3.0; it is not a measured transfer result.
Is B09RXJHHX7 verified as HB-MAC3?
No. The historical Amazon page was unreadable and the model page does not map that ASIN.
Where can I check the current price?
