Ultra-thin laptops and 2-in-1 convertibles like the Microsoft Surface Pro offer great mobile productivity and sleek good looks. But that also means they usually come up short on connectivity ports. The SD3500v USB 3.0 Universal Docking Station turns one USB port into six so you have access to all your peripherals, including keyboard, mouse, printer and external hard drive. With dual HD video output, you can add two external monitors boosting productivity. The dock's two USB 3.0 ports support super-speed data transfer of up to 5 Gbps.
