USB Car Charger

USB Car Charger

USB car charger: usually also referred to as the USB car charge. It exploits the versatility of USB's versatility to be applied to a variety of charging interfaces. Then the combination should be used in the car, the car's DC 12V and DC 24V into USB and the common 5V DC voltage of each charge. In this way, we can use the standard power supply on the car and the USB interface to charge the 5V DC. Such as: mobile phone, MP3, navigation, game machines and all the 5V DC appliance.

working principle
First: USB car charger must be consistent with a principle, for small consumer electronics

The USB port is an economical and practical power source for the device's battery charging. To fully comply with the USB 2 specification, the load connected to the USB port must be able to communicate with the host. The load must also meet the power management requirements, including low power mode, as well as the means to facilitate the host to determine when to absorb large current from the port. Although some compatible systems are able to adapt to most USB hosts, unexpected results may occur at times. Only a good understanding of the requirements of the USB specification and the expectation of the load can achieve a better balance between the compatibility of the specification and the complexity of the load. So USB car charger, from the interface to the conversion of the voltage, and the requirements of the current power to match the needs of electrical appliances. Sometimes you will encounter the USB you buy can not be charged to your electrical appliances, so that there may be a problem of matching. For example: do you use the electrical voltage is USB car charge 5V DC voltage. If the voltage is correct, it is possible that your power. USB car charging power may not match, there may be no charge, or insufficient power. At this time it is to confirm the charging current big and small is a match.

USB based on the above factors: it is the first to turn the car's power supply 12V DC or 24V DC into 5V DC; and then the output of the 5V DC using USB unified interface to the corresponding electrical. Based on different electrical power is different, USB car charger is also different, mainly different from the USB car charging current.


USB vehicle charging specifications

USB car charger commonly used specifications: output: DC 500mA 5V;

5V DC 700mA;5V DC 1000mA;5V DC 2000mA;
DC 700mA 5V; DC 1000mA 5V; DC 2000mA 5V; 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 car charger price
USB the price of the car with the USB filling specifications have a different relationship, may look exactly the same, but the output of the label is different, the price is not the same. Usually the current is greater, the greater the power, the higher the price. Price can be divided into the cost price, the factory price, wholesale market price and retail price. Here from the user's point of view, roughly say about the retail price. In the network sales platform price 3-80 range, which is mainly in the power of the product and the different prices of materials.
