      Dear valued customer, Thank you for the comment.
      As for the charging up to 86%, it's recommended to fully charge and discharge the power bank a few times to calibrate the battery.
      If the issue persists, please let us know.
      Thank you!
      please feel free to contact us.(service@energizerpowerbanks.com) We will be glad to assist you.
