Be Careful! Do Not Let The Car Charger Become A Stealth Killer
Nov 08, 2017

With the rapid development of smart phones, powerful large-screen smart phone almost a hand, 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 charger came into being, and quickly spread to most of the owners.

In order to meet the development of the market, the market appeared on various types of car charger, with all the variety is the variety of product categories, good and bad quality, and even occurred in the car charger to use improper damage to the accident. So today, "little four children" just like to talk about the principle of car charger, as well as the choice of car charger to pay attention to the problem

The principle of car charger

Car charger principle is to car cigarette lighter socket 12V voltage into 5V USB voltage and charge the electronic product through the charging cable. Generally speaking, the car charger is 12V (car 12V, truck 24V) DC into 5-20V DC power for the car mobile equipment charging, which is characterized by small power consumption, simple and convenient, cheap.

Car charger in the use of the Notes

1. Please be careful not to insert the car before the start of the car, so as not to start the car when the voltage damage car charger

2. Owners in the use of time, do not use strong chemicals, cleaning agents, strong detergent cleaning charger. Because it will seriously damage the car charger function.

3. In particular, pay attention to the use of the vehicle during the car do not throw, floor, beat or shake the charger, and when the summer long-term stagnation vehicles and the car temperature exceeds 45 ℃ when not to use the charger, this will be seriously damaged Car charger inside the circuit board.

4. Car charger as one of the electronic products, the owner in the use of the process, we should pay attention not because of inadvertent water or prolonged when not exposed to the humid air, so that its internal electronic components will cause different degrees of corrosion Or oxidation.

5. After the vehicle is turned off, the car charger should be unplugged. 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.

Purchase notes

May most of the owners will think that a simple charger all manufacturers do almost, just pick a price is not cheap on the line. But now flooded the market all kinds of "cottage" car charger after another, charging current virtual problem, charging heat problems, LED small lights dazzling impact driving safety problems are beginning to show. So in the end what kind of car charger is good, the product price is really about the product performance, "small four children" summed up the following four points to buy Note:

1. Select the product 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.

2. Select the product with output current of 1A or more

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. To battery capacity 1470mAh iPhone4S, for example, 1A current charging only about 2 hours can be filled, and poor product charging time will need to double.

What is more when you use those charging current in the 500mA charger for mobile phone charging, if you are opening the phone navigation state, this time not only fully charged into the electricity, and sometimes the phone will go down! So when you choose the car charger must be optimistic, at least choose to charge current 1A or more products.

3. Please purchase regular licensed

Must buy regular manufacturers through the safety certification of products, do not buy and use three no products, or out of the quality of complaints no door, regret the late carry on. In particular, can not seek cheap to buy 20 dollars below the brand, the current domestic mainstream brand car charger price more than 20-100 yuan up and down
