Much more convenient than having two cables, worth the money.

I needed this cable to connect my dock to my ThinkPad P15 Gen 2. Cable works great!

Great having just this cable to power and charge my PC. I keep an extra charger in my bag for traveling, so when I come in or leave the office all I have to worry about is the split cable going to my docking station and I'm ready to go.

Much needed cord for dock. The only way to apply one cord to power both the dock and computer, without an additional cord.

This is good for Gen8 and below version of the Carbon X1 devices. If you upgrade to new docks, the USBC type 4 cable will do everything needed.

Received the product, works great between my Laptop and docking Station. This new way to connect is much better than the old way!

Super handy to not need to run seperate cables to power the laptop and connect to the docking station.

Needed to replace the thunderbolt connection cord on my Lenovo docking station. This cord works on the Thunderbolt 4 and Thunderbolt 3 docking stations. It works fantastic and is exactly what I was looking for. The price is reasonable and cheaper than getting the v3 cord. Highly recommend

This "ThinkPad Thunderbolt 4 WorkStation Dock Split Cable 0.7m" (Part Number: 4X91K16970) works perfectly with my ThinkPad Thunderbolt 3 Workstation Dock Gen 2 (Part Number: 40ANY230US) & my P15 Gen 1 (20SUS09800) Laptop (ThinkPad). It was both cheaper and more available than the specified replacement Thunderbolt 3 split cable (Part Number: 5C10V25713) that my dock came with.
