There are many kinds of mobile power supplies currently on the market, and the battery capacity of the charging treasure is large and small, and the batteries used are different. In general, the larger the capacity, the heavier the charging treasure. So is the charging treasure of the same capacity light or good?
If the capacity of the two charging treasures is the same and the volume is not much different, the charging weight is better, the weight is heavier, the volume is not real. However, the weight of different batteries is not the same. It is recommended that consumers buy more well-known brands when purchasing charging treasures, and purchase charging treasures with clear labels. Don't buy cheap inferior charging treasures.
