USB Car Charger Power Consumption Is Small, Simple And Convenient
With the development of science and technology market, the basic per capita of smart phones, especially with the development of automotive interconnection technology in recent years, mobile phone and car more and more closely, which also led directly to the consumption of mobile phone faster, so the car charging Device came into being, and quickly spread to most of the owners.
However, the quality of the product is uneven, and most of the owners to use the way to the vehicle caused by the loss.
USB Car Charger works
The car cigarette lighter socket 12V voltage into 5V USB voltage and charge the electronic product through the charging cable. Generally speaking, the USB Car Charger is 12V (car 12V, truck 24V) DC into 5-20V DC power for the car mobile device charging, which is characterized by small power consumption, simple and convenient.
Precautions for use
① Remove the car before the start of the car, so as to avoid the vehicle when the voltage damage USB Car Charger.
② owners in the use of time, do not have strong chemicals, cleaning agents, strong detergent cleaning charger. Because it will seriously damage the USB Car Charger function.
③ USB Car Charger as an electronic product, if the damp or water, it is recommended not to continue to use, so as to avoid internal short circuit caused by security risks.
④ develop a USB Car Charger after the flame out of the habit.
Select products with overload protection
USB specification requirements for current overload protection shall not exceed 5A. USB Car Charger is the need for overload protection because when the output current is too large and more than their normal output value, the charger component life will be shortened or because the temperature is too high lead to damage or even burning. So the USB Car Charger used in the car must have overload protection measures.
2Select the output current of 1A or more products
USB Car Charger on the market are basically 12V-24V input voltage, the output voltage of 5V, while the output current is about 1A-4A.
If the phone provides navigation function is charging, poor quality charger can not only provide normal charging and power will continue to decline.
Please buy regular, quality assurance products
To buy regular manufacturers through the certification of products, do not buy and use three no products, or prone to quality problems or cause security risks
