Information

The dc power adaptor is widely used in today's electronic product market and has a large consumption. For example, it can be used in electronic products such as mobile phones, notebook computers, some small-sized LCD TVs, set-top boxes and printers. Because the dc power adaptor has many product models and specifications, and the overall price is low, when the original dc power adaptor fails and cannot be used, usually users will choose to buy products with the same parameters. However, some non-original dc power adaptors on the market now have problems, and some of them have not passed the CCC safety certification compulsory by the state, which poses a safety hazard to users. Users can refer to the following aspects when purchasing products.

dc power adaptor
(1) The dc power adaptor belongs to the national CCC compulsory certification product. When purchasing, you should check whether the product packaging and shell have CCC certification. You cannot buy products without CCC certification. When purchasing a product, the user can ask the seller to provide the CCC certificate number of the product. Check the validity of the certificate on the CCC product certification public service platform to know whether the product's technical specifications, commodity certification and certificate description are consistent.
(2) When purchasing a product, you should pay attention to whether the information such as its trademark, specification and model, manufacturer's name and implementation standards are accurate and consistent, and whether the auxiliary accessories are complete.
(3) According to the use environment of the product, reasonably determine the required specifications, and do not purchase a dc power adaptor with an output that is too small or too large. If the output voltage and current of the dc power adaptor are insufficient, it is very likely that the battery cannot be fully charged, or the connected electronic products may be unstable, such as screen beating or unexplained crashes. If the output of the dc power adaptor is too large, the electronic product will be overloaded, and the device may be damaged if used for a long time.
