Do you want to buy a powerbank to charge your electronic devices outdoors? Then pay attention to the capacity (mAh) and the output or power (W) of the powerbank. It is also important to know where and for which device you want to use the powerbank and how many products you want to charge at the same time.
How often and how long you need to charge a powerbank depends on its power. The amount of mAh (milliampere hour) indicates how powerful the powerbank is. The larger the mAh, the more often and the longer the powerbank can charge other devices before it is empty.
After a while, your powerbank loses some of its power. Therefore, always charge it fully and only repeat this when it is completely emptied.
This depends on the capacity of the powerbank and the power of your smartphone. Xtorm maintains this standard:
To find out how many times you can charge your device with a particular powerbank, divide the power of the powerbank by the power of your device.
