How often and for how long you have to charge a Powerbank depends entirely on the power of your Powerbank. The power of the Powerbank is indicated by the amount of mAh. The mAh indicates how powerful the Powerbank actually is. The larger the mAh, the more often and longer the Powerbank can charge. How often you can charge your device also depends on the device you want to charge. A camera needs less power than, for example, a mobile phone or a tablet.

You can divide the power of your Powerbank by the power of your gadget device. With the outcome of this you can deduce how often you can charge your gadget. Just like the battery of your phone, the Powerbank also loses some of its power over time. Therefore, always fully charge your Powerkbank and always let it drain completely until you recharge it. This is how you best retain the power of your Powerbank.
