Zusammenfassung:	Systems and methods are provided for charging a chargeable electronic device with a USB interface. An example method includes comparing a charging voltage level of a charging device to a charge voltage rage. The method may further include charging a battery with a charging current based on the charging voltage level being within the charging voltage range. The method may further include comparing the charging current to a charge current range, and increasing the charging current based on a determination that it is within the charge current range. The method may involve again comparing the charging voltage level to the charge voltage range and the charging current to the charge current range, and continuing to charge the chargeable electronic device with the charging current based on a determination that the charging voltage level is within the charge voltage range and the charging current is within the charge current range.
