SpecPicks Verdict

SpecPicks scored Hiearcool 7-in-1 USB C Hub using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Hiearcool's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this hub output 4K at 60Hz to my monitor?

No. HDMI output is rated up to 3840x2160 at 30Hz. For 60Hz, the hub supports 1080p. If you need 4K at 60Hz, look for a hub rated for it.

Does it work with my phone or iPad for video out?

Video out only works if your device's USB-C port supports DisplayPort Alt Mode. Hiearcool lists iPad Pro as compatible, but not all phones and tablets support video output. Check your device's specs.

Can I charge my laptop through the hub while using it?

Yes. The USB-C PD pass-through port accepts up to 100W. Your laptop receives that power minus what the hub uses, and the actual rate depends on your charger, cable and device.

How fast are the USB-A ports and can they run an external SSD?

Both USB-A 3.0 ports support up to 5Gbps and are listed for SSD enclosures and flash drives. Each port supplies up to 5V/0.9A, so a drive that draws more power may need its own power source.

Does it need drivers on Mac or Windows?

No. The hub is plug-and-play with no drivers required. Hiearcool lists compatibility with MacBook Pro and Air, Dell, HP, Lenovo and Surface laptops, plus other USB-C devices.
