Targus 17" Dual Fan Chill Mat gives you a comfortable and ergonomic work surface that keeps both you and your laptop cool. The dual fans are powered using a standard USB-A connection that can also be connected to your laptop or computer using a mini-USB cable. Includes a USB hub to help share the USB connectivity used to power the built-in fans. Soft neoprene material on the bottom provides cushioned comfort while the Chill Mat is sitting on your lap. Its ergonomic tilt makes typing easy on your hands and wrists. Open mesh top allows airflow to quickly move away from your laptop, ensuring constant cooling when you need to work. Four rubber stops on the face help prevent the laptop from slipping and keeping it stable during use. Built-in 4-port hub allows connection to your peripherals during use. Adjustable height (4 levels) lets you use the Chill Mat as a laptop stand with an external keyboard, while the bottom ledge keeps the laptop in place. Hook-and-loop straps help keep all your peripheral cables neat and tidy. Also comes with limited 1-Year manufacturer warranty.
