Patent number: 11502528Abstract: 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.Type: GrantFiled: March 11, 2021Date of Patent: November 15, 2022Assignee: DURACELL U.S. OPERATIONS, INC.Inventors: Jordan Todorov Bourilkov, Sergio Coronado Hortal, Francisco Jose Restrepo, John Rotondo
