Charging desk lamp is LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, with lithium battery and USB charging function, the LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light.
USB charging desk lamp is a desktop or laptop computer USB mini rechargeable lamps. Is through the computer connected to the computer USB interface, downy light, most of the charging desk lamp can adjust the brightness of the light, two control as you need to change, is very convenient. The USB port on the computer (that is, everyone is used to insert USB interface) for external voltage of 5 v power supply for the equipment, the current 500 ma, USB charging small desk lamp of desk lamp is with USB interface to provide power supply, lamp take up the space is not too much, and very save electricity, suitable for office workers or students.
