The 332 gives you a 4K HDMI output, one USB-C 5 Gbps data port, two USB-A 3.0 data ports running at the same 5 Gbps, and a 100W USB-C pass-through charging port. For a possible setup, that’s an external monitor, two peripherals (keyboard and mouse, or a drive and a drive), and your laptop charging simultaneously from a single port on your machine. The hub draws that cable mess down to one connection, which is more or less the entire pitch of USB-C hubs, and something Anker executes cleanly here.

Pass-Through Power
The charging side makes this sub-$20 hub more than worth it. The hub supports up to 85W pass-through, so with a 100W source charger connected to the PD-in port, your laptop gets 85W delivered while everything else runs. That’s enough headroom to actually charge a MacBook Air or MacBook Pro under normal workloads rather than just slowing the discharge rate. A lot of cheaper hubs advertise pass-through charging and then deliver 45W or 60W, which is fine for phones but frustrating for laptops pulling real power. Anker being specific about 85W is a more useful number than the vague “fast charging” language that appears on competitors at this price.
One important note from the product specs: The USB-C 100W port is charging-only and doesn’t support data transfer. Headphones, speakers, or USB-C storage drives need to go to the 5 Gbps data port or the USB-A ports. That’s a limitation if you expected four full-service USB-C connections, but it’s not an unusual design choice at this price tier.
