USB car charge commonly used specifications: output: DC 500mA

DC 700mA 5V; DC 1000mA 5V; DC 2000mA 5V;when you understand the output voltage of its specifications are DC 5V, you can find that there are a variety of specifications of its current. The different current specifications are convenient to use and choose to apply to different electrical appliances. In the past, the mobile phone is basically 500mA current; but with the development of the times, mobile phone business, mobile phone, mobile phone, music, Internet phone, etc., its power. So the current needs of the charger is relatively large. The different specifications of the USB car to allow users to select the appropriate matching specifications.

USB the price of the car with the USB filling specifications have a different relationship,it may look exactly the same, but the output of the label is different, the price is not the same.
