[This review was collected as part of a promotion.] Sadly I had to return a higher power rated dock due to compatibility issues with the older Lenovo mobile Workstations being able to use a square connection power cable, where as this new P16 Gen 3 only takes USB type C connections... And as soon as I received it, as my travel power cable, I put it to use on a week trip. It powered the P16 and my two external monitors, too, which connect to my P16 Gen 3 via a USB type C single cable, each, so it reduces the amount of cables required from previous laptop use. Powers everything I need.
I did not realize this would not charge my laptop. Otherwise it works well
No, I would not recommend this to a friend.
