Date:Mar 29, 2019

Nowadays, there are more and more mobile phone functions, and the battery charge is getting faster and faster. It is the madness of the madman to go out without the phone. However, the car chargers on the market are mixed, improperly selected, and will cause damage to the car. So what kind of car charger is the "I am good or good" car charger? When buying, these 3 points should be noted.

1. Select products with overload protection

The USB specification requires no more than 5A for current overload protection. The reason why the car charger needs overload protection is because when the output current is too large and exceeds its normal output value, the life of the charger component will be shortened or the temperature will be too high, resulting in damage or even burning. Therefore, the car charger used in the car must have overload protection measures.

2. Select products with output current above 1A

The input voltage of the car charger on the market is basically 12V-24V, the output voltage is 5V, and the output current is about 1A~4A. However, some "three no" or "cottage" products generally have a phenomenon of charging current imaginary. Take the iPhone 4S with a battery capacity of 1470mAh as an example. The 1A current charging can be fully charged in about 2 hours, while the charging time of inferior products needs to be doubled.

What's more, when you use the charger with charging current of 500mA to charge the mobile phone, if you are turning on the navigation status of the mobile phone, you will not be fully charged, and sometimes the mobile phone will go down! Therefore, when choosing a car charger, be sure to be optimistic, at least to select a product with a charging current of 1A or more.

3, please buy regular licensed

Be sure to buy regular manufacturers to pass the safety certification products, do not buy and use three no products, otherwise there is no way to complain about quality problems, regret late. In particular, you can't buy cheaper brands with less than 20 yuan. At present, the price of car chargers for domestic mainstream brands is around 20-100 yuan.

Precautions for using the car charger

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

2. When the owner is using it, do not use harsh chemicals, cleaning agents or strong detergents to clean the charger. This will seriously damage the function of the car charger.

3, in particular, do not pay attention to the car charger in the process of throwing, landing, knocking or vibrating the charger, and when the vehicle is stagnant for a long time in the summer and the temperature inside the car exceeds 45 °C, do not use the charger, it will be seriously damaged The circuit board inside the car charger.

4, car charger as one of the electronic products, the owner of the car in use, be careful not to accidentally enter the water or exposed to humid air for a long time, this will cause different degrees of corrosion on its internal electronic components Or oxidized.

5. The car charger should be unplugged after the vehicle is turned off. Although 80% of the vehicles are powered by the cigarette lighter after the vehicle is unplugged, some of the car's cigarette lighters are continuously powered.
