StarTech.com 2-Port Thunderbolt 4 Hub (Thunderbolt 4 / 2 Ports / No Charging / No Display Output / Mac/Windows / ~$70) Review
The StarTech.com 2-Port Thunderbolt 4 Hub is a bare-bones port expander with just two Thunderbolt 4 ports and nothing else, no display output, no charging, no Ethernet, aimed purely at daisy-chaining one extra Thunderbolt device off a laptop that's already out of ports.
Every other dock in this catalog tries to do more with more ports, displays, and charging. This one deliberately does less: it takes a single Thunderbolt 4 port and splits it into two, full stop. For someone whose laptop has only one Thunderbolt port but two Thunderbolt peripherals to connect, like an external drive and a display adapter, this hub solves that specific problem for a fraction of what a full dock costs, without paying for docking features they'll never use.
Comparison to Alternatives
Against the CalDigit Element Hub, the Element Hub adds three extra USB-C ports and 60W of charging for a similar price, making it the better value if you need any charging at all, while the StarTech stays purely about Thunderbolt port count. Against the Plugable TBT4-UDZ, the Plugable is a full 16-in-1 dock with quad display support, illustrating just how stripped down the StarTech hub is by comparison, useful only for the narrow case of needing one more Thunderbolt port.

Expert rating5 / 10
Does exactly one job, adding a second Thunderbolt port, and does it cheaply; not a dock replacement.
Best for
- Laptops with only one Thunderbolt port needing to daisy-chain a second device
- Users who already have display and charging solved and just need port count
- Minimalist setups that don't want to pay for unused dock features
Not for
- Anyone needing display output, since it has no video ports at all
- Anyone needing the hub to charge their laptop
- Buyers wanting a full-featured docking station rather than a pure port splitter
