Choosing the capacity of a portable energy storage power supply requires consideration of the usage scenario and the battery capacity of the required charging device. Generally speaking, the larger the capacity, the more times it can be charged and the longer the usage time. But larger capacity energy storage power supplies will also be more cumbersome and inconvenient to carry.

 

If you only charge small devices such as smartphones and tablets, a portable energy storage power supply with a capacity of over 10000mAh can meet the demand. If you need to charge large devices such as laptops, you need to choose an energy storage power supply with a capacity of over 20000mAh.

 

The duration of use depends on the capacity of the energy storage power supply and the battery capacity of the charging device. Taking a 10000mAh energy storage power supply as an example, if the battery capacity of the charging device is 3000mAh, it can be charged about 3 times. At the same time, the charging speed and usage environment can also affect the usage time.

 

In summary, selecting the capacity of a portable energy storage power supply requires a comprehensive consideration of the usage scenario, the battery capacity of the required charging device, and the portability requirements that need to be carried. Meanwhile, the usage time depends on factors such as the capacity of the energy storage power supply and the battery capacity of the charging device, as well as the usage environment and charging speed.
