How to buy a safe power adapter
time2019/05/10
- Power adapter products are increasingly used in a wide range of electrical products, so how can I buy a safe power adapter?
Power adapter products are increasingly used in a variety of electrical products, especially information technology equipment, telecommunications terminal equipment and audio and video equipment, such as: notebook computers, tablets, mobile phones, multimedia players, LCD monitors.
Consumers can hardly distinguish their quality when purchasing a power adapter, but you can pay attention to the following points:
(1) Preferred products that have been certified by “CCC”, if possible, check the authenticity and validity of their certificates on relevant websites.
(2) Check the identity of the power adapter. Qualified products must contain information such as the rated input voltage or rated voltage range, the nature of the power supply, safety instructions, etc. Consumers should not purchase power adapter products with full foreign language identification.
(3) Select the power adapter that matches the machine. Before purchasing the power adapter, you need to know the basic information such as the electrical parameters of the whole machine used with it, and the output voltage must be consistent with the rated voltage of the whole machine.
(4) Check the plug and connector of the power adapter. Loose interface will make the current received by the whole machine unstable, and it may form a large instantaneous current, which will cause damage to the whole machine. If the interface is too tight, it will not be easy to insert or remove the interface.
