With USB ports on laptops becoming a precious commodity, an external hub can be the answer to maintaining optimal productivity. The UH4000C USB 3.0 4-Port Hub & Charger ensures you can connect all your peripheral desktop accessories to your laptop, as well as quickly charge your smartphone or tablet. Leveraging USB 3.0 technology, each of the four ports can support lightning fast transfer speeds so you can work more efficiently. The ports also double as chargers, ensuring the battery on your favorite devices never runs out. With 3 AMPs available, you can use any of the ports to provide a fast charge for a tablet and a smartphone, or other combination of low power devices. Because there are no drivers to download, simply insert the USB cable it into your laptop, plug in the power cord, and you're ready to go.
