    In hot summer days, you stay in the office where the area is large, though the air conditioner works, you still feel stuffy. Here I recommend you usb fans.

    A usb fan is any fan that makes use of a USB port for power. USB ports are standard features on most modern computers, on many other electronic devices, such as video game consoles, personal digital assistants (PDAs), smartphones, and digital video recorder (DVR) boxes. A USB fan allows a user to make use of these ports for cooling purposes.

    USB fans come in a wide array of sizes and forms, from standard desktop fans to smaller, more functional computer case fans. Whatever design they adhere to, though, they all must work within the limitations of the USB specification and therefore can draw no more than 5 volts of power. This means that most USB fans will be relatively small in size and suitable for a desktop environment.

    The biggest feature of usb fans is convenience. As long as you plug in the USB port, you can generate a cool breeze immediately without no batteries. USB fan can also be carried anywhere in laptop bags. USB fan blades are made of soft plastic film sheet. Though the rotation speed is high, it is safe.

    You can buy usb fans for your family and friends as gifts.
