I bought a small solar power generator for my father the year before. Usually it will be more convenient to use it when the power is cut off. Yesterday, dad called me to tell me that the power supply of the solar energy seemed to be a bit of a problem. I didn’t know whether it was a bad contact or what. I went back to look at it, as if the line was aging. I should have to change a new one. So I went to the shop that bought the solar power plant to ask if I could sell power supply alone, and the customer service came back to me, so I took a power supply again, because I still trusted the store’s products and bought it for so long that I didn’t have any problems, so I believe that The new power supply has been used for several years.
