Satechi TB4 Slim Hub Pro Review 2026 - Specs & Pros

7.4 Very Good
Adrian Cel By Adrian Cel

The Satechi Thunderbolt 4 Slim Hub Pro is a focused, minimalist Thunderbolt 4 hub designed for users who need to expand their Thunderbolt port count without the bulk of a full-size docking station. Announced at CES 2024 and priced at $199.99, it delivers three downstream Thunderbolt 4 ports and a single USB-A 3.2 Gen 2 port in a sleek, aluminum enclosure that matches Apple's Space Gray aesthetic perfectly. Where most docking stations try to cram in every port imaginable, Satechi takes the opposite approach: strip away the Ethernet, HDMI, DisplayPort, card readers, and audio jacks, and instead give you four Thunderbolt 4 ports that each deliver the full 40Gbps bandwidth. The result is a hub built for one specific job: splitting one Thunderbolt connection into multiple high-speed downstream ports for displays, storage, and peripherals. The Pro version is a meaningful upgrade over the original Satechi Thunderbolt 4 Slim Hub, boosting power delivery from 60W to 96W thanks to a larger 150W GaN power supply. This makes it capable of charging even a 16-inch MacBook Pro during normal use. At just 0.53 pounds and roughly 5.5 by 3 inches, it is one of the most portable Thunderbolt 4 hubs available, sliding easily into a laptop bag or backpack.

Best Portable Hub

Pros & Cons

What We Like

  • Extremely portable at 0.53 lbs, fits easily in a laptop bag
  • 96W Power Delivery charges even 16-inch MacBook Pro
  • Three Thunderbolt 4 downstream ports with full 40Gbps each
  • Supports daisy-chaining up to six Thunderbolt devices
  • Premium aluminum build that matches Mac aesthetic
  • 150W GaN power supply is compact for its wattage
  • No drivers required, true plug and play

What Could Be Better

  • Only 5 total ports: no Ethernet, HDMI, DisplayPort, audio, or card readers

    Workaround: Use Thunderbolt downstream ports to connect adapters or a secondary dock for missing connectivity.

  • No dedicated video output, must use Thunderbolt downstream ports for displays

    Workaround: Connect USB-C/Thunderbolt displays directly, or use a USB-C to HDMI/DP adapter on one of the TB4 ports.

  • Only one USB-A port limits legacy device connectivity

    Workaround: Use a USB-A hub on the single port, or connect USB-A adapters to the TB4 downstream ports.

  • Base M1/M2/M3/M4 Macs limited to single external display

    Workaround: This is an Apple limitation, not a Satechi issue. Consider a DisplayLink dock for multi-display on base Apple Silicon.

  • $199.99 is steep for a 5-port hub without diverse connectivity

Our Verdict

Very Good

The Satechi Thunderbolt 4 Slim Hub Pro is a well-executed product for a niche audience. If you own a MacBook Pro or a Windows Thunderbolt 4 laptop and your primary need is more Thunderbolt ports (for connecting high-speed external SSDs, daisy-chaining Thunderbolt peripherals, or driving dual 4K displays), this hub does the job well. The 96W power delivery is a genuine improvement over the original model and puts it in the same charging territory as full-size docks like the CalDigit TS4. Build quality is excellent, as expected from Satechi, and the compact form factor makes it ideal for hybrid workers who move between home and office. However, the Slim Hub Pro is not a docking station replacement. It lacks Ethernet, dedicated video outputs, SD card readers, and audio jacks. If you need those features, you should look at a full-featured dock like the CalDigit TS4 or the Kensington SD5700T. The $199.99 price is fair for the quality and Thunderbolt 4 certification, but it can feel steep for what is essentially a Thunderbolt splitter with one USB-A port. For the right user (a creative professional with Thunderbolt storage, a developer daisy-chaining peripherals, or a MacBook owner who simply needs more TB4 ports), the Satechi TB4 Slim Hub Pro is a solid, portable pick.

Frequently Asked Questions

Does the Satechi TB4 Slim Hub Pro support dual monitors?
Yes, the hub supports dual 4K@60Hz displays when connected via two of its three Thunderbolt 4 downstream ports. On Mac, you need an M1 Pro, M1 Max, or later chip for dual display support. Base M1/M2/M3/M4 Macs are limited to one external display due to Apple Silicon limitations.
What is the difference between the Satechi TB4 Slim Hub and the Slim Hub Pro?
The Pro version upgrades the power supply from 60W to 96W charging (via a 150W GaN brick instead of a 96W adapter), meaning it can charge larger laptops like a 16-inch MacBook Pro. The port configuration is identical: both have 3 downstream TB4 ports and 1 USB-A 3.2 Gen 2 port. The Pro costs $199.99 versus $149.99 for the original.
Can the Satechi TB4 Slim Hub Pro replace a full docking station?
Not for most users. The Slim Hub Pro is a Thunderbolt port expander, not a docking station. It lacks Ethernet, HDMI, DisplayPort, SD card readers, and audio jacks. If you need those features, consider a full dock like the CalDigit TS4. The Slim Hub Pro is best suited for users who primarily need additional Thunderbolt ports for storage and displays.
Does the Satechi TB4 Slim Hub Pro work with Windows laptops?
Yes, it works with any Windows laptop equipped with a Thunderbolt 4 port, including Intel Evo-certified laptops from Dell, Lenovo, HP, and Microsoft Surface. It supports dual 4K displays, 40Gbps data transfer, and 96W charging on compatible Windows devices.
Is the Satechi TB4 Slim Hub Pro good for travel?
Yes, it is one of the best travel-friendly Thunderbolt 4 hubs available. The hub itself weighs just 0.53 pounds and measures roughly 5.5 x 3 inches. The included 150W GaN power supply is also relatively compact. Both fit easily in a laptop bag or backpack.
