3. Minimize the simultaneous charging of multiple devices and try to avoid charging large power devices (load is too large)
To remind everyone that the car charger must pay attention to more problems during use
1, start and then charge Note that after the engine starts, insert the device and then charge. When the car is ignited, the voltage is low, which can affect the charging effect and even damage the car charger.

When you purchase a car charger, you generally need to pay attention to the following points:
1, confirm the safety device: In addition to well-known brands, the owners should also understand whether the selected car charger shell flame retardant compliance, and whether there is over-current protection device. Generally, a car charger with a relatively small volume may not be installed with over-current protection, and it is necessary to avoid buying.
2, choose a well-known brand: owners in the purchase of car charger should try to choose well-known brands, regular manufacturers of products, although the price will be relatively high, but the quality will be more secure.
3. Do not pursue high current: When the current is too large or the interface is too much, the faults and dangerous conditions encountered may be even more, so when the car owner purchases the car charger, it is better not to blindly pursue high current, multiple interfaces and charging speed. . In addition, some car chargers currently on the market still have virtual voltage and current conditions. We must pay attention when buying and using.
4. Do not buy unprotected products: Do not buy products that are too low in price and do not buy or use unprotected products. Make sure that the product packaging is printed with production standards.
We only use the car charger correctly, and the service life of the product is longer. Therefore, for security, we must buy regular brands, buy genuine, poor quality products are vulnerable to security risks. When using it, be sure to follow the correct method.
