Shared power banks, often used as a lifesaver for quick charging in public spaces, have lately sparked widespread concern due to the prevalent issue of 'continued charging after return.' After returning the power bank, many users find that their phones still indicate the charging session is active, resulting in unauthorized charges. This usually stems from issues like improper return methods, inserting the power bank incorrectly, obstructions in the charging slot, returning it to a different brand's station, or the device not being properly powered off. To avoid such inconveniences, users are advised to meticulously ensure the power bank is correctly returned to the designated slot and to check the device's indicator light for confirmation of a successful return.
