Thenumber of times that the power bank can be used for charging depends on its remaining power supply, the battery capacity of the charged device, the quality of the charging cable, and the charging environment.

Withhigher quality components like you find in the Cascade, you can expect to get about 80% of the total charge transferred to your device. That's why we tell our customers to expect the Cascade 10000mAh power bank to recharge their smartphone about three times and the 6000mAh Cascade power bank about two times.
A10,000mAh power bank should be able to charge the smartphone up to three times and a 20,000mAh power bank more than six times. You can calculate the approximate number of charges by dividing the power bank's measured capacity against your phone's stated capacity. Therefore a power bank with a 10,000 mAh capacity (real capacity 6,000-7,000 mAh) can charge the majority of smartphones at least two times to 100% capacity. The tradeoff is that power banks this size typically weigh more and are bigger than your phone.4years ago. Updated.
