Product warranty for one year, long-term customers can enjoy a lifetime warranty provided by the company, can be done according to customer requirements for system voltage and current parameters. Switching power adapter selection must be noted: 1, power adapter marked above power, current, and some of the data, but also pay attention to the output voltage range should be selected according to their own needs, do not be because of excessive pursuit of price or high-tech while ignoring their needs. 2, switching power adapter manufacturers to choose the good, the gap between high-quality products and inferior products are small, totally do not need to save in this regard. Inferior product life is short, easy to heat, heat the product if it is serious, it is recommended to replace the adapter. If because of inferior products cause our digital products are damaged, then it is not worth the candle. 3, high-quality switching power supply has a leakage protection. The key is inside each of the parts are in accordance with the choice of safety certification standards and procedures for production. Safety performance, high reliability, complete the relevant certification.
