The quality of Xin Lingxiao charger is not very good, and the charger often fails to charge when it is hot, as if this brand has a bad reputation in the industry.
The materials used in Xin Lingxiao are cheaper, which may also be because the price of Taobao has squeezed the cost into this way. On the PCB surface, Xin Lingxiao's PCB is easy to burn. If there is a risk of fire due to poor ventilation, you can use it with low current, and it is not recommended to use it with too high current.
Take the prefix charger as an example to preliminarily judge the quality of a charger.
1. Look at the appearance: the electrical performance specifications are clearly marked, and the information such as the manufacturer's address and batch number is clear, depending on the shell plastic and process texture. See if the printing on the outside of the wire is complete and the safety certification information is complete.
2. Weigh the weight. A good transformer radiator is bigger and heavier. Look at the size of the internal radiator and transformer through the gap of the cooling hole, and see how the fan looks.
3. Plug in the battery first to see if the light is on, so don't use the lighted charger. There is no reverse connection protection, and there is a risk of short circuit and fire. Shake the charging plug tightly.
