Review on Cable Matters USB C Dock for Windows - Dual 4K DisplayPort, 80W Charging, SD Card Slot, 10Gbps USB-A/USB-C Gigabit Ethernet - Thunderbolt 4 / USB4 / Thunderbolt 3 Port Compatible USB C Docking Station for Enhanced Performance by Caleb Olsen

Since Microsoft hasn't integrated Thunderbolt 3 into the Surface Book 2, we're limited to using regular USB-C docks. The problem is that the vast majority of options on the market only provide 60W via USB Power Delivery. With discrete graphics models, this is not enough to charge the laptop properly under load. Another problem is that most USB-C docks limit you to a specific bandwidth allocation. Or you get GbE Ethernet, USB 3.1 ports and a display with a maximum resolution of 2560 x 1440 x 60Hz. Or a 4Kx60Hz display but limited to USB 2.0 speeds. This docking station solves both problems. 80W PD is usually enough to quickly charge a 13.5-inch SB2 (although it would be nice to see 90W or 100W). And there's a dynamic bandwidth allocation switch that you can play around with depending on the resolution of your monitor and the speed your peripherals need. It's also very reliable actually charging the laptop and detecting the monitor. The Dell WD -15 that I've used so far has been extremely successful, only successfully telling the laptop to charge about 30% of the time and successfully displaying an image on the monitor 50% of the time. great product A bit pricey but you get what you pay for!
