There are often a lot of car owners who reflect that their car USB charger feels very slow when charging, the charging efficiency is too low, I don’t know what the reason is, some car USB chargers are not used for a long time, but why is this happening?
First of all, the car’s cigarette lighter is a key point to pay attention to. Many car owners often pull out the car USB charger directly. If the car’s cigarette lighter is not covered, the car’s cigarette lighter will be eroded for a long time. The contact between the car charger and the cigarette lighter is poor, which affects the charging.
Secondly, after many times of plugging and unplugging, the components of the plug of the car USB charger are subject to large wear, and some even have a drop in plug elasticity, which is a big problem. The cause of this problem is often the poor quality of the car USB charger. After repeated plugging and unplugging, it cannot recover enough elasticity. When the plug is inserted into the cigarette lighter, it can not effectively contact the cigarette lighter, resulting in poor contact.
Finally, the charging current of the car USB charger does not match the current of the charging device. This is an important factor affecting the charging effect. Many car owners do not know much about this charging current, so they are more casual in choosing the car USB charger. For example, the original charger for the iPad is 2A, but if you choose to charge with a 500mA or 1A current charger, the charging speed will definitely become very slow, even if your charger is new; there are also owners who want to charge speed With a charger larger than 2A, using a 2.5A or 3A or higher charger, then although the charging speed may be faster, it is risky in terms of safety.
So, what should we do about the slow charging of the car USB charger? Through the above analysis, we can know that when choosing the car USB charger, we must pay attention to the quality of the product, the fake product can not be effective quality assurance and even security risks. Therefore, it is recommended that the owner of the car must choose a regular manufacturer when choosing. The car chargers of well-known brands rarely have such problems, and they are selected according to the needs of their own charging devices. Both charging speed and charging safety are guaranteed.
