No, the capacity can not be blindly large, we should pay attention to the quality of charging. Mobile power supply is mainly for emergency reserve, it can not completely replace the charger.

1. Mobile power supply is totally inferior to charger in terms of speed and voltage stability.

2. Mobile power supply is still inflammable and explosive. If we want to control the capacity of batteries above 1W mA, the price will rise greatly in terms of the control unit and the quality of the batteries.
