Any product will have its useful life, and different product life cycles will be different. However, due to the difference in materials and processes, the same product will have a different service life. Some low-cost, low-quality power adapters have various quality problems in use. So what quality problems might the power adapter have in use?
1, no logo, no certification, no quality assurance. The price of such a product is relatively low, but the quality is very poor, and once the problem occurs, it cannot be solved.
2. Excessive fever during work. The power adapter works by voltage conversion and generates a certain amount of heat during operation. However, when overheating, it is necessary to consider the problem of power adapter.
3. The short circuit and overload protection are faulty. When the output overload protection is short-circuited, the internal damage of the power adapter and the sharp rise in temperature may cause damage to the electronic products during charging.
How do we tell the quality of the power adapter?
1. Check if the certificate of the power adapter is valid.
In the control of the power adapter, it is a mandatory national certification directory. Therefore, the formal power adapter in the market is subject to national compulsory certification. When we purchase the power adapter, we first look at the nameplate to indicate whether the certification mark is printed. In addition, we can check the certificate model of the product online. If the product is certified, then we can choose this power adapter.
2, carefully check the power adapter logo
The second step is to look at the interface and plug of the power adapter. First, make sure that the size of the DC head is the same as the one you are using. If the dimensions do not match, then there is no way to use it.
3. Check the interface and plug of the power adapter
Then look at the DC head is loose, because the interface of the power adapter is unstable, it will cause the current to be unstable, which will cause damage to the equipment and cause a safety accident.
