Smartphones can meet the various needs of users anytime and anywhere, and almost everyone has a smartphone. However, as the screens of smart phones continue to grow larger, the power consumption of smart phones is accelerated. When people are out on a trip, such as shopping, playing in a park, going on a trip, etc., the situation of insufficient power of the mobile phone often occurs. For this reason, most people generally solve the urgent need of insufficient power of smart phones by carrying mobile charging devices such as charging treasures.
