How much do you know about car chargers? This article tells you...

With the rapid development of smart phones and in-vehicle interconnection technologies, the connection between mobile phones and cars has become closer and closer, and various types of car chargers have appeared on the market. There are also a variety of product categories with varying quality. There have even been incidents of car damage caused by improper use of on-board chargers. The following introduces the principles of car chargers, and the issues that should be paid attention to when buying and using car chargers.


The principle of car charger

The principle of the car charger is to convert the 12V voltage of the car cigarette lighter socket into a 5V USB voltage and charge the electronic products through the charging cable. Generally speaking, car chargers convert 12V (car 12V, truck 24V) DC power into 5-20V DC power for charging mobile devices on-board. It is characterized by low power consumption, simplicity and convenience, and low price.


Car charger socket type

After understanding the construction principles of car chargers, let's take a look at the types and styles of common car chargers.

1. Classified by USB socket

Single USB car charger: only one USB output port, only one electronic device can be charged at a time

Dual USB car charger: There are two USB output ports, which can charge multiple devices at the same time

2. Take the full class with the line car

Micro plug car charger: Many brands of mobile phones on the market now use this type. It can be said that the Android system uses this kind of thread.

Mini plug car charger: This is the interface that was used a few years ago, but it is rarely used now. Due to the thick notch, the body is not thin.

3. Classified by charging equipment

Mobile phone car charger

Electronic dog car charger, lithium battery car charger

Navigator, driving recorder car charger

High-power electric car charger

4. Cigarette lighter car charger

These are classified according to the different types of car chargers and charging objects. People with different needs can choose different types of car chargers, which can save unnecessary trouble.


How to choose a car charger

1. First of all, no matter what power product you choose, safety is the first. Choose 3C certified safety products. Do not buy and use Sanwu products, otherwise there will be no complaints if there is a quality problem!

2. Don't blindly pursue high current and charging speed, because excessive current will often cause greater danger when encountering line faults; the power of the charger is a very important technical parameter, such as: use a low-power charger Charging high-power devices will cause low-power chargers to be burned out due to overheating (for example, the IPAD charger cannot charge the IPAD).

3. Choose a car charger with automatic protection function. A better quality car charger will have functions such as overcurrent, overvoltage, overheating and short circuit protection, and it will be safer and more assured to use.

4. Regarding the choice of materials, there are multiple options for aluminum alloy car chargers, stainless steel car chargers, plastic car chargers, and metal car chargers. This depends on your own preferences. Try to choose flame-retardant and environmentally friendly materials, which are beautiful and safe.


How to use car charger correctly

1. Please be careful not to insert the car charger before the car starts, so as not to damage the car charger when the voltage is started.

2. When the car owner is in use, never use harsh chemicals, cleaning agents, or strong detergents to clean the charger. Because this will seriously damage the function of the car charger.

3. Be especially careful not to throw, drop, knock or vibrate the car charger during use, and do not use the charger when the vehicle is stagnant for a long time in summer and the temperature inside the car exceeds 45°C. This will cause serious damage the circuit board inside the car charger.

4. Car charger is one of the electronic products. During use, car owners should be careful not to accidentally enter water or expose them to humid air when they are not used for a long time, which will cause different degrees of corrosion to their internal electronic components or oxidation.

5. After the vehicle is turned off, the car charger should be unplugged and placed. Although 80% of the vehicles are powered by the cigarette lighter after the vehicle is removed from the key, there are also some cars whose cigarette lighter is continuously powered.
