Size:3 x Fast Charge USB-A Port, 1 x USB-C | Color:Black Here’s an easy way to connect a wider range of peripherals to your laptop. This 4-port USB 3.0 hub turns your laptop’s USB-A port into three USB-A charge-and-sync ports (5Gbps), and one USB-C port. Now, you can use your laptop’s traditional USB Type-A port to expand your connectivity, fast-charge your smartphone or tablet, and connect your newer USB Type-C device to your laptop. This USB 3.0 hub lets you expand your USB connection options using the USB-A port on your computer. (USB 3.0 is also known as USB 3.1 Gen 1.) It offers three USB-A ports and one USB-C port, so you can still connect traditional USB devices now, and be ready to connect USB Type-C devices in the future. It’s the ideal way to connect your new USB-C equipped device to your laptop’s traditional USB-A port. With three fast-charge ports, this hub helps ensure that your tablets and smartphones are charged and ready to use when you need them. Each USB-A port supports USB Battery Charging Specification 1.2, so you can charge and sync up to three devices simultaneously. (The charge provided depends on the number of devices connected and the amount of power each device draws. The hub’s USB-C port does not support charging.) This self-powered USB hub comes with an external power adapter to support power-hungry USB devices, such as larger external drives and enclosures, which require more power than USB power can provide on its own. You can install the versatile USB 3.0 hub virtually anywhere, because it takes up minimal space on a desk, and fits perfectly in hot-desk or BYOD environments. With its compact and lightweight design, the 4-port USB hub is also ideal for mobile use. You can simply tuck the hub and power adapter into your laptop bag to expand your connectivity when you’re traveling. This hub can help if you need a way to connect your newer USB-C peripherals to your existing laptop. The HB30A3A1CSFS is backed by a 2-year StarTech.com warranty and free lifetime technical support.
