SABRENT Thunderbolt 4 Hub Review 2026 - Specs, Pros & Cons

7.4 Very Good
Adrian Cel By Adrian Cel

The SABRENT Thunderbolt 4 Hub is a compact Thunderbolt port expander aimed at users who want more high-bandwidth USB-C and Thunderbolt connections without moving up to a full docking station. Model HB-TBT4 gives you one upstream Thunderbolt 4 connection for the laptop, three downstream Thunderbolt 4 ports, and one 10Gbps USB-A port in a small aluminum enclosure. SABRENT rates the hub for up to 40 Gbps data, up to 60W host charging through PD 3.0 bypass charging, dual 4K displays at 60Hz, or a single 8K display at 30Hz, with 8K at 60Hz requiring DSC 1.2. The official materials also call out support for a single 4K display at up to 144Hz and mention backwards compatibility with USB-C hosts, though the best experience still comes from a real Thunderbolt laptop. A certified 15.7-inch Thunderbolt 4 cable and a 20V/6A external power supply are included. At $169.99 MSRP, this sits close to entry-level Thunderbolt 4 hubs from Belkin and Satechi, but with lower laptop charging than the best alternatives.

Compact TB4 Hub

Pros & Cons

What We Like

  • Three downstream Thunderbolt 4 ports at up to 40 Gbps each
  • Compact aluminum design with good passive heat dissipation
  • Dual 4K@60Hz support on compatible Thunderbolt hosts
  • Certified Thunderbolt 4 cable and external power supply included
  • No drivers required on supported Mac and Windows systems
  • Backwards compatible with USB-C hosts for basic connectivity

What Could Be Better

  • Only 60W host charging, below the 90W to 96W offered by several competing TB4 hubs

    Workaround: Use your laptop's original charger if it regularly draws more than 60W, or choose a higher-power Thunderbolt dock.

  • No built-in HDMI, DisplayPort, Ethernet, audio jack, or card reader

    Workaround: Use the downstream Thunderbolt 4 ports with adapters or add a separate dock for broader I/O.

  • Display output requires a host with DisplayPort Alt Mode support

    Workaround: Check your laptop's USB-C or Thunderbolt specs before buying. Not every USB-C port carries video.

  • Base warranty is only one year unless you register the product

    Workaround: Register the hub with SABRENT after purchase to extend warranty coverage to two years.

7.4 /10

Our Verdict

Very Good

The SABRENT HB-TBT4 gets the basics right. You get the core Thunderbolt 4 hub layout most people want - three downstream TB4 ports, one USB-A port, no drivers, and enough bandwidth for fast storage plus dual 4K displays. The compact aluminum body and included certified cable are both nice touches, and the official user reviews on SABRENT's own store are mostly positive, with a 4.7/5 average from 69 reviews at research time. The catch is power delivery. 60W is enough for ultraportables, MacBook Air, and many 13-inch laptops, but it is a step down from 90W to 96W rivals that better suit larger workstations. Port variety is also minimal, so you need adapters for HDMI, DisplayPort, Ethernet, audio, or card readers. That keeps this from being a true one-cable desktop dock. If you mainly need to split one Thunderbolt connection into several more Thunderbolt ports, the HB-TBT4 is a practical option. If you need stronger charging or broader connectivity, a full dock is the better buy.

Frequently Asked Questions

How many Thunderbolt ports does the SABRENT HB-TBT4 have?
The hub has four Thunderbolt 4 ports total. One connects upstream to your laptop, and three remain available as downstream Thunderbolt 4 ports for displays, storage, or other accessories.
Can the SABRENT Thunderbolt 4 Hub run dual monitors?
Yes. SABRENT rates the HB-TBT4 for dual 4K displays at 60Hz on compatible Thunderbolt hosts. It can also run a single high-resolution display, including 5K, 6K, or 8K depending on the host, display, and whether DSC is supported.
Does the SABRENT HB-TBT4 charge a laptop?
Yes. The upstream Thunderbolt 4 host connection supports up to 60W of PD 3.0 bypass charging. That is enough for many ultraportables and office laptops, but it is less ideal for larger high-performance notebooks.
Does the SABRENT Thunderbolt 4 Hub include HDMI or Ethernet?
No. This is a pure Thunderbolt hub, not a full dock. You get three downstream Thunderbolt 4 ports and one USB-A port, but no built-in HDMI, DisplayPort, Ethernet, audio jack, or card reader.
What is the warranty on the SABRENT HB-TBT4?
SABRENT lists a one-year warranty by default. The company also says you can extend coverage to two years by registering the product after purchase.
