How to choose a car charger
1.Look for big brands. Because the barriers to entry in the car charger industry are relatively low, the market is full of uneven car charger products, so when you buy, try not to choose a brand you have never heard of. The quality of big brand products is more guaranteed, and they will be available. Overvoltage, overcurrent, overheating, short circuit protection and other functions make it safer to use.
2.Look at the material and design. Common materials are plastic (must be flame-retardant) and metal. Although there is no difference, metal car chargers often have a higher level of design, such as CNC, polishing, and laser carving. , Electroplating and other processes, so the overall appearance should be a grade higher, and the feel is much better. Of course, the price is obviously more expensive.
3.Fast charging is essential. More and more mobile phones now support fast charging. Although car chargers only meet the fragmented charging needs, the faster the better. If the charging is too slow, the power charged in the mobile phone navigation is not even enough to consume the power. . Whether it supports fast charging depends on its output parameters. 5V/1A, 5V/2.1A, and 5V/2.4A are all common, mainly depending on whether it supports fast charging protocols such as QC3.0. Some car chargers support fast charging with both USB ports, and some only support fast charging. You can choose according to your needs.
Precautions for the use of car chargers
1.When using the car charger, please pay special attention not to throw, drop, knock or vibrate the charger at will during use, and do not use charging when the vehicle is stagnant for a long time in summer and the temperature inside the car exceeds 45°C. This will seriously damage the internal circuit board of the car charger.
2.Remember not to insert the car charger before the car starts, so as not to damage the car charger by the voltage when the car starts.
3.Do not use harsh chemicals, cleaning agents, or strong detergents to clean the charger when the car owner is in use. Because this will seriously damage the function of the car charger.
4.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.
5.Finally, as one of the electronic products, car chargers should be careful not to accidentally enter water or expose to humid air when they are not used for a long time. This will cause varying degrees of internal electronic components corrosion or oxidation.
