  • Patent number: 12007450
    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.
