  • 100W USB-C power delivery charges host while working
  • 5Gbps USB 3.1 data on USB-A and USB-C ports
  • 5W downstream charging powers phones and accessories
  • Compact 3-in-1 adapter adds HDMI USB-A USB-C to Type-C hosts

Portable 3-in-1 USB-C dock

The Rocstor Y10A306-B1 adds HDMI, USB-A and USB-C female ports to a single Type-C or Thunderbolt host. It targets laptop users who need external display output and legacy peripheral connectivity from one compact adapter. The male Type-C plug connects directly without a separate cable.

HDMI 4K 60Hz and dual data paths

The HDMI port delivers 4K at 60 Hz using DisplayPort 1.4 Alt mode and supports HDR with HDCP 2.2 and 1.4. The USB-A port provides 5 Gbps data plus 7.5 W downstream charging. The USB-C female port handles 100 W PD 3.0 pass-through charging and 5 Gbps data when a device is attached.

Single-display and single-device limits

The dock drives one external monitor at 4K 60 Hz and cannot support multi-monitor setups from a single port. The USB-C female port accepts either a PD charger or a data device, not both simultaneously. Users needing multiple displays or concurrent charge-plus-data on the Type-C port require a larger dock.

Questions about this item

Will the HDMI port need a firmware update to keep working with future 4K 60Hz displays?

No firmware updates are required; the built-in DisplayPort 1.4 Alt mode IC handles 4K at 60Hz natively.

What limits the USB data speed when I run the HDMI, USB-A and USB-C ports together?

Each USB port tops out at 5 Gbps via USB 3.1, so simultaneous transfers share that bandwidth ceiling.

How hot does the adapter get when it passes 100W PD and 4K video all day?

The aluminium housing dissipates heat from 100W power delivery and 5 Gbps data without active cooling.
