What should be paid attention to when using the car charger?

Charger is an electronic device that people use everyday. According to the type of charger, the charger can be divided into wired and wireless chargers. With the different objects of the charger, it can be divided into other types. and Car charger It is also the daily necessities of frequent drivers. Let's know and understand the hazards, purchase and points for attention of on-board connectors.

1、 Hazards of on-board charger.

Car charger The principle is to convert 12 volts into 5 volts to charge the mobile phone. However, due to the price limitation of vehicle charger, the circuit design has many defects, and the circuit has almost no protection function. In case of voltage reduction and current limiting failure during operation, 12V voltage may directly enter the mobile phone and directly endanger the mobile phone. Therefore, it is recommended to upgrade the on-board inverter to 220 V, and use the original or high-end charger to ensure the safety of mobile phone battery. Where the car is plugged in for charging, the output voltage is between 12v-24v. If the quality of the car charger is not very poor, it generally does not affect the charging of the mobile phone, but it is recommended not to use it often.

2、 How to buy Car charger 。

1. Identify big brands.

Car charger The entry threshold of the industry is low, and most of the car charger products in the market are mixed with fish's eyes, so try not to buy brands you haven't heard of. The quality of big brand products is more guaranteed, with functions such as overvoltage, overcurrent, overheating and short circuit protection, which is safer and more comfortable to use.

2. Look at materials and design.

Common materials are plastic (must be flame retardant) and metal. The filling of metal car has a higher level in design, such as CNC, polishing, laser engraving, electroplating and other processes, so the overall value should be a higher level, and the feel is much better. Of course, the price will be more expensive.

3. Fast charging is crucial.

Nowadays, more and more mobile phones support fast charging. Although the on-board charger can only meet the fragmented charging demand, the faster the better. If the charging is too slow, the mobile phone is not even charged enough during navigation. Whether it supports fast charging mainly depends on its output parameters. 5V / 1a, 5V / 2.1a and 5V / 2.4a are common, which mainly depends on whether fast charging protocols such as qc3.0 are supported. yes , we have Car charger Both USB ports support fast charging, and some only support fast charging, which can be selected according to needs.

III Car charger Problems needing attention in use

1. When using the on-board charger, pay special attention not to throw away, land, knock or vibrate the on-board charger at will. The vehicle stops for a long time in summer. Do not use the charger when the temperature in the vehicle exceeds 45 ℃, which will cause serious damage Car charger Internal circuit board.

2. Do not insert the car charger before starting the car, so as to avoid voltage damage to the car charger during starting.

3. Never clean the charger with strong chemicals, detergents or strong detergents. This will cause serious damage Car charger The function of.

4. When the vehicle is off, unplug it Car charger And place. Although 80% of the vehicles stop the power supply of the cigarette lighter after removing the key, the cigarette lighter of some vehicles will continue to supply power.

5. As one of the electronic products, vehicle owners should pay attention not to be exposed to humid air due to accidental water inflow or long-term non use, which will cause varying degrees of corrosion or oxidation to its internal electronic components.
