Abstract: A reusable battery indicator includes a voltage sensor, a communication circuit communicatively connected to the voltage sensor, an antenna operatively coupled to the communication circuit, and a connector. The connector is electrically connected to the voltage sensor, and the connector is adapted to be removably connected to a battery, thereby providing an electrical connection between the voltage sensor and the battery. An electrical circuit is completed between the voltage sensor and the battery and the voltage sensor. The connection mechanism includes part of an electrical lock and key assembly.

Abstract: 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.

Abstract: 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.

Abstract: 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.
