Our Take

Best for: Best for Thunderbolt laptop users needing multiple monitors and wired networking.

The Tiergrade Thunderbolt 3 Dock is a solid 18-in-1 hub for anyone with a Thunderbolt 3 or 4 laptop. It turns a single port into a full workstation with dual 4K or single 8K display support, fast USB-A and USB-C data ports, SD card slots, and a Gigabit Ethernet jack. The 60W power delivery keeps your laptop charged, and the separate 15W downstream Thunderbolt port is handy for peripherals. What stands out is the sheer number of ports for the price. 0 ports for mice and keyboards. The DisplayPort and Thunderbolt 3 outputs handle high-resolution monitors, though M1 Mac users are limited to one external display. 6 feet, which is short for desktop setups. 05, this is a fantastic value. 99, so you're saving over 50% compared to recent prices. It's not the all-time low (data not available), but it's close. If you need a versatile Thunderbolt dock without spending $200+, this is a no-brainer.

Price Analysis

The current price of $67.05 is 44% off the original $119.60 and well below the 30-day average of $119.60. The 90-day average was $136.99, and the 180-day average was $172.78, making this a rare low. This is an excellent time to buy, as the price is near historic lows.

Common Questions

Does this dock work with M1 MacBooks?

Yes, it works with M1 MacBooks, but you can only connect one external monitor due to the M1 chip's limitation. The dock will still provide all other ports and power delivery.

Can I charge my laptop through this dock?

Yes, the Thunderbolt 3 host port delivers up to 60W of power delivery, which is enough to charge most laptops like MacBook Pro, Dell XPS, and Lenovo ThinkPad.

Does it support 8K resolution?

It supports single 8K at 30Hz via the DisplayPort or Thunderbolt 3 port, but this requires an Intel Core i11 or newer laptop, a compatible 8K monitor, and a proper DP cable.
