Hiearcool USB C Hub Multi-Port Adapter, 7-in-1 USB-C Dongle with 4K HDMI 100W PD SD/TF Card Reader
Quick take
This compact 7-in-1 USB-C hub turns one USB-C port into HDMI (up to 4K at 30Hz), two USB-A 3.0 ports, and SD plus microSD card readers, with USB-C PD pass-through up to 100W. It is a practical option for MacBook Pro/Air and many Windows laptops that support DisplayPort Alt Mode for video out. The main buying caveat is that your device must support DP Alt Mode for the HDMI to work.
Pros and cons
Pros
- 7-in-1 port selection for everyday needs: HDMI, 2× USB-A 3.0 (5Gbps), and SD/microSD readers.
- USB-C power delivery pass-through for charging up to 100W input (actual delivery depends on your setup).
- Plug-and-play design, no drivers required.
- Compact aluminum build that is easy to pack for work or school.
Cons
- HDMI video requires a USB-C port with DisplayPort Alt Mode, not all USB-C devices support this.
- HDMI support tops out at 4K at 30Hz, which is fine for typical work and media, but not aimed at high-refresh gaming.
- Only two USB-A ports are included, so it might feel limited if you need multiple peripherals at once.
What buyers think
Buyer feedback is broadly positive, with recurring themes around convenience and everyday reliability. Many users describe it as easy to set up and quick to use with MacBook setups, including situations where they connect a monitor plus peripherals without constantly swapping cables. The hub’s portability and compact size also come up often, especially for people using it in a bag for work or school. Some buyers who used it as a substitute for a docking station mention it “just works” after plugging in, and that it has held up well over longer periods. Overall, review evidence supports that the hub is practical for adding ports and expanding a laptop workspace, with limited evidence suggesting the primary concern is compatibility for HDMI video, not day-to-day failures.
What you get (ports and key features)
The Hiearcool hub is built for one-cable expansion. It adds:
- HDMI video: Mirror or extend displays up to 3840×2160 (4K) at 30Hz, with support for 1080p at 60Hz.
- Two USB-A 3.0 ports: data up to 5Gbps, helpful for flash drives, keyboards, and mouse receivers, or other USB-A devices.
- SD and microSD card readers: for importing photos, transferring files, or expanding workflow for creators and students.
- USB-C PD pass-through: up to 100W input so your laptop can receive power while the hub is connected (the exact power you get depends on your charger, cable, and the device).
- Compact aluminum design: made to be travel-friendly.
HDMI compatibility is the make-or-break detail
If HDMI output is important to your buying decision, check your laptop first. This hub relies on USB-C DisplayPort Alt Mode for video. Many USB-C laptops that support external monitors via USB-C will work, but phones and tablets without DP Alt Mode (or laptops with only charging and data but no DP Alt Mode support) will not output video. If you are unsure, look for DP Alt Mode support on your device’s USB-C port or user documentation.
Charging and power delivery pass-through
The hub supports USB-C power delivery pass-through up to 100W. In practice, this means your charger can plug into the hub while you use HDMI and USB accessories, reducing cable clutter. Just remember that your laptop receives power minus the hub’s consumption, so your real charging rate will depend on your power brick and your specific laptop model.
Speed and real-world use cases
For day-to-day tasks, the hub’s specs line up well with common workflows:
- Work and study: HDMI for a monitor plus USB-A for a mouse and keyboard, plus card readers for assignments or shared materials.
- File transfers: USB 3.0 (up to 5Gbps) can help with moving data to and from external storage or accessories.
- Travel: a single compact hub reduces the number of adapters in your bag.
Pros and cons summary
- Buy it if: you want a compact USB-C hub with HDMI (4K at 30Hz), USB-A 3.0, and SD/microSD readers, and your device’s USB-C port supports DP Alt Mode.
- Skip it if: you need high-refresh HDMI output for gaming, you require more than two USB-A ports, or your device does not support DisplayPort Alt Mode over USB-C.
Verdict
The Hiearcool 7-in-1 USB-C hub is a solid “one-cable” expansion choice for MacBook and Windows laptop users who want HDMI, dual USB-A, and SD/microSD in a travel-friendly aluminum body. Its biggest limitation is not the port selection, it is compatibility: HDMI output depends on DP Alt Mode. If your setup supports that, this hub looks well suited for everyday monitor use, charging pass-through, and on-the-go file transfers.
