USB car charger

USB Car Charger: commonly referred to as a USB car charger. It takes advantage of the versatility of American B's extensive use in a variety of charging ports. Combined with the use of automotive, automotive 12V DC and 24V DC conversion USB charging electrical appliances and a variety of commonly used DC 5V voltage. This form of electricity charges standard, and can use the car's USB port, DC 5V. Such as: all 5V mobile phone, MP3, navigation system, game console and other dc electrical appliances.

The working principle

First: USB car chargers must adhere to a principle for small consumer electronics

A USB port is an economical and practical power source for recharging batteries. Fully compliant with the USB 2.0 specification, the USB port connected to the load must be able to perform two-way communication with the host. The load must also meet power management requirements, including low power mode, and ease of determining when to draw large current from a means host port. While there are some compatible systems to accommodate most USB hosts, there are sometimes unpredictable results. There is only a good understanding of the complexity of the load between the USB requirements and the load expected to standardize compatibility to achieve a better balance. So USB car charger, switch from the interface to the voltage conversion, and the current power demand to match the electrical demand. Sometimes, you will encounter a USB that you can't buy to give you the charge, so there may be a problem with matching. For example, if you are using a 5V dc USB car charger voltage. If the voltage is correct, and this is your electrical power may be larger. USB car charger power mismatch, may not be able to charge or charge less power. Then, it should confirm whether the charging current is large and small.
USB is based on the above factors: its first car is DC 12V or 24V DC power to DC 5V; Then a unified interface USB 5V DC output transmits the corresponding charge. Different according to different power sources, USB car charger power is also different, different from large and small USB car charger mainstream.

USB car charger specification

Common specifications USB car charger: output: 5V DC500 mah;

5V DC700 ma; 5V DC 1000 mah; 5V DC2000 mah; Know its specification output voltage 5V DC, you can find various current specifications. The ease of use of this different current specification is selected for different devices. For example, in the past, mobile phones were basically 500 milliamperes; But with the development of The Times, mobile phone appears business mobile phone, mobile phone games, music, Internet phone, its power. Therefore, the current needs of the charger are relatively large. This is a USB car charger of different specifications, users can choose the corresponding specifications.

USB car charger price

Price USB car charger USB specification is inextricably linked, it may look the same, but different label output, the price is not the same. Usually the current, the greater the power, the higher the price. Price can be divided into cost price, factory price, market wholesale price and retail price. Here, but from the user's point of view, talk generally about retail prices.
