Small Configuration Can Not Be Overlooked, The Car Charger The Correct Way To Open
The development of the times, the progress of science and technology, the increasing income per capita, which led to the people's living conditions more and more impressive, as a large range of communications supplies and transportation products into the people's family. Speaking of mobile phones and cars, although they have a world of difference, but these two products have a certain relationship.
Today, the phone's power storage capacity as one day a day, when people driving the car if the sudden power failure will cause a great impact, delay things. Therefore, the car charger this equipment is popular to the majority of the owner of the hands, but the quality of car charger uneven, and many owners do not know how to use, but a problem, will bring you huge losses. Xiaobian today to share with you under the car on the car's knowledge
First, the working principle of car charger
This stuff is the car cigarette lighter socket 12V voltage into 5V USB voltage, and then link the power cord can be charged after the phone. Normally, the car charger will 12V (car 12V, truck 24V) DC into 5-20V DC power for the car mobile device charging, is characterized by small power consumption, simple and convenient, cheap.
This configuration is simple and easy to use, but if improper operation will lead to damage to electronic equipment, or even dangerous.
Reminder Note: It is best not to insert the car charger before starting the vehicle, or connect the power supply to the phone, so as to avoid the unstable voltage generated when the vehicle starts to damage the charger and mobile phone.
Reminder Note 2: When the car charger used for a long time after the dirty, do not use strong chemicals, cleaning agents, strong detergent cleaning charger. Wipe with a wet tissue and dry it to avoid damage.
Reminder Note 3: In particular, be careful not to use the car charger during the random throw, floor, beat or shake the charger. Especially in summer when the sun was sun exposure, the car temperature over 45 degrees, temporarily do not use the charger, and this will seriously damage the car charger inside the circuit board.
Reminder Note 4: car charger is an electronic device, the owner in the course of the use, do not put it in a long time in a humid environment, so as not to its internal electronic components caused by varying degrees of corrosion or oxidation. If you accidentally sprinkle water on the charger should be removed immediately and dry, so as to avoid damage to the circuit board.
Reminder Note 5: After the vehicle is turned off the car charger should be unplugged, if long-term plug in the power interface, the contact part of the two may be corrupt and difficult to remove. Although 80% of the vehicles are the vehicle to remove the key after the cigarette lighter to stop power supply, but there are some car cigarette lighter is continuous power supply.
Careful use of car charger is on the one hand, on the other hand also need to pay attention to is to buy products with overload protection.
USB specification requirements for current overload protection shall not exceed 5A. 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 car charger used in the car must have overload protection measures.
Second, select the output current of more than 1A products
Car charger on the market input voltage is basically 12V-24V, the output voltage of 5V, while the output current is about 1A ~ 4A. But some "three no" or "cottage" products are generally appear charging current virtual standard phenomenon. If you use the phone navigation is charging, low-quality charger can not only provide normal charging and power will continue to decline.
