Thunderbolt 3 Dock with 85W Power Delivery
The Belkin Thunderbolt 3 Dock Pro serves as a central hub for laptops, delivering up to 85W of charging power while expanding connectivity. It supports a single display at 8K (7680 x 4320) or dual displays at 4K (3840 x 2160). The unit suits professionals who need a streamlined workstation with high-resolution video output and laptop charging through one cable.
Mini U Speaker Adds Wireless Audio
The bundled Mini U Speaker connects via Bluetooth for hands-free, cord-free audio playback and calls. Its 400 mAh battery provides up to 4 hours of playback per charge. The compact speaker measures 45.45 mm x 33 mm (1.75" x 1.3") and includes a Micro USB charging cord. This addition turns the dock into a complete audio-visual workstation without extra wiring.
Multi-Port Build Simplifies Desk Wiring
The dock housing integrates Thunderbolt 3, USB-A, USB-C, DisplayPort, Gigabit Ethernet, SD card reader and audio in/out ports. Wired Ethernet ensures stable network access without relying on wireless signals. The single-cable host connection reduces cable clutter significantly. Buyers who need more than two external displays or higher laptop charging wattage should verify their requirements against the 85W limit and dual-display specification.

Questions about this item
How often will the Mini U speaker's 400 mAh battery need recharging during a typical workday?
The speaker provides up to 4 hours of playback per charge, so plan to recharge it via Micro USB at least once during an eight-hour day.
Which video output caps resolution first when driving two monitors for hours?
Dual displays are limited to 3840 x 2160 each, so the 4K ceiling is reached before the single-display 7680 x 4320 capability.
Does the dock's 85 W charging generate noticeable heat or fan noise during all-day use?
The dock runs silently with no moving parts; warmth is normal at full 85 W load but stays within safe operating limits.
