Abstract: A portable power bank for charging a mobile computing device is described, and a dynamic charging efficiency is monitored while the power bank is charging the mobile computing device. Particularly, instantaneous power output of a battery of the power bank is compared to power received by a battery of the mobile computing device to determine efficiency. The charging of the mobile computing device by the power bank is interrupted and/or resumed based upon the charging efficiency at any given time, thereby preventing inefficient use of the power bank.

Abstract: A portable power bank and mobile computing device are described, where the mobile computing device includes a rechargeable battery that receives electric charge from the power bank via an electrical connection. Systems and methods facilitate determination of a “number of potential rechargings” of the mobile computing device battery via the power bank, e.g., how many times the power bank can charge the mobile computing device battery to a desired fuel gauge (e.g., 100%) before the power bank is depleted. The number of potential rechargings is determined based upon the desired fuel gauge of the mobile computing device, present fuel gauges of the mobile computing device and the power bank, and charging efficiency factors corresponding to the mobile computing device and the power bank, respectively.

Abstract: A portable power bank including a rechargeable battery may detect loss of capacity in the power bank battery. The power bank determines a nominal capacity of the power bank, and an actual capacity of the power bank, the actual capacity being less than the nominal capacity. The power bank compares the actual capacity to the nominal capacity to determine a health value of the power bank battery. When the power bank battery health value is at or below a threshold value, the power bank transmits an indication of the health value to a mobile computing device.
