The Targus Chill Mat for netbooks features two fans that generate cool air to keep the netbook running efficiently and to help prevent overheating. The Chill Mat can be also used in the office to protect furniture from heat damage, or on the go to protect your lap from heat. Rubber grips keep your netbook in place to provide a sturdy workspace. Ideal for travel, the Chill Mat is highly portable and features built-in cable management. The device plugs directly into the USB port so no additional power is required.
