With it, you have room for older accessories along with the ability to plug in newer gear (as more tech moves toward USB-C connections) without having to plug in a collection of separate adapters into your laptop. And with the capabilities to handle both old and new tech, this hub supports up to two 4K displays at 60Hz, or a single 8K display, depending on your computer and its connections. For professionals, especially those in a WFH environment, the dual-monitor option is particularly useful. Now you can have a document up on one screen, and your research, email, or spreadsheet on another screen.\ This dock can also serve as a laptop charger up to 90W, letting you leave your charger in the bag or stashed away. The one thing it does mention is that if your laptop needs more than 90W for charging, it may be unstable while charging, so check that before you decide. While customers who have bought and used it appreciate the port selection, there are mixed feelings about reliability, notably with certain Mac models, so it's best to double-check that first. That said, if you're looking for maximum port connectivity and a decent price, this one is hard to beat right now.
