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.

Monitoring capacity of a power bank battery and devices charged therewith

A portable power bank including a rechargeable battery and/or a remote server may detect loss of capacity in the power bank battery. The power bank and/or remote server 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 and/or remote server 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 and/or remote server transmits an indication of the health value.

Integrated monitoring capacity of a power bank battery and devices charged therewith

A portable power bank for charging a rechargeable device is described, and a dynamic charging efficiency is monitored while the power bank is charging the rechargeable device. Particularly, instantaneous power output of a battery of the power bank is compared to power received by a battery of the rechargeable device to determine efficiency. The charging of the rechargeable 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.

Integrated monitoring charging efficiency of a rechargeable device via a power bank

Battery pack

A portable power bank and remote server are described, where a rechargeable 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 rechargeable device battery via the power bank, e.g., how many times the power bank can charge the rechargeable device battery to a desired fuel gauge (e.g., 100%) before the power bank is depleted. The number of potential rechargings is determined by the remote server based upon the desired fuel gauge of the rechargeable device, present fuel gauges of the rechargeable device and the power bank, and charging efficiency factors corresponding to the rechargeable device and the power bank, respectively.
