What do you know about car charger? This article tells you

With the rapid development of smart phones and vehicle Internet technology, the relationship between mobile phones and vehicles is becoming more and more close. Various types of vehicle chargers have appeared in the market, along with a variety of product types, the quality of which is uneven, and even the event of vehicle damage caused by improper use of vehicle chargers has occurred.


Therefore, today, Taige is going to talk about the principle of car charger and the problems that should be paid attention to when purchasing and using car charger.

Principle of car charger

The principle of car charger is to convert 12V voltage of cigarette lighter socket into 5V USB voltage and charge electronic products through charging cable.

Generally speaking, the car charger is to convert 12V (car 12V, truck 24V) DC into 5-20v DC for car mobile device charging, which is characterized by low power consumption, simple and convenient, and low price.
Plug type of vehicle charger


After understanding the construction principle of car charger, let's take a look at the types and styles of common car chargers.
Classification with USB socket
1. Single USB Car Charger
There is only one USB output port, which can only charge one electronic device at a time
2. Dual USB Car Charger
There are two USB output ports, which can charge multiple devices at the same time


Classification of vehicles with lines
1. Micro plug car charger
low many brands of mobile phones on the market are of this kind. It can be said that the Android system is universal.
2. Mini plug car charger
This is a few years ago, the interface used more, now rarely used, because the slot is thick, resulting in the fuselage is not thin.
3. DC plug car charging.
Classification by charging equipment
1. Mobile car charging
2. Electronic dog car charging, lithium battery car charging
3. Navigator, dash cam, vehicle charging
4. High power electric vehicle charging

Filling of cigarette lighter
These are classified according to different types of charging and charging objects. Different types of vehicle charging can be used for old fellow iron cars with different demands, so they can save unnecessary trouble.
How to choose car charger

1. First of all, no matter what power supply products you choose, safety is the first. You should choose 3C certified safety products. Do not buy and use Sanwu products, or you will have no way to complain about quality problems!
2. Don't blindly pursue high current and charging speed, because excessive current will cause great danger when encountering line fault; the power of charger is a very important technical parameter, for example: charging high-power equipment with low-power charger will cause low-power charger to burn out due to overheating (for example, the charger of iPod can't charge iPad).
3. Select the car charger with automatic protection function. Better quality car charger will have over-current, over-voltage, overheating and short circuit protection functions, it will be more safe and assured to use.
4. The choice of materials includes aluminum alloy car charger, stainless steel car charger, plastic car charger and metal car charger. It depends on your own preference. Try to choose flame retardant and environmentally friendly materials, which are both beautiful and safe.
How to use car charger correctly


1. Please pay attention not to insert the car charger before the car starts, so as not to damage the car charger due to the voltage when the car starts.
2. Do not use strong chemicals, detergent or strong detergent to clean the charger. Because this will seriously damage the function of the car charger.
3. Pay special attention not to throw, fall to the ground, knock or vibrate the on-board charger during use, and do not use the charger when the vehicle stops for a long time in summer and the temperature inside the vehicle exceeds 45 ℃, which will seriously damage the circuit board inside the on-board charger.
4. As one of the electronic products, car charger owners should pay attention not to accidentally enter the water or be exposed to humid air when not in use for a long time, which will cause different degrees of corrosion or oxidation to the internal electronic components.

5. The on-board charger should be removed and placed after the vehicle flameout. Although 80% of the vehicles are powered off after the key is removed, some of the vehicles are powered on continuously.
