A universal charging device and a universal charging method thereof is disclosed. An AC voltage is converted into a DC charging voltage. At least two first charging processes are sequentially performed. In each first charging process, the DC charging voltage is adjusted to be larger than the terminal voltage of a battery based on the terminal voltage and the DC charging voltage charges the battery. The DC charging voltage generates a DC charging current and a pulse current to flow through the battery until the terminal voltage is equal to the DC charging voltage. A voltage across the battery established by the pulse current satisfies a charged condition. When the terminal voltage is equal to the DC charging voltage, the DC charging current is converted into a decreasing trickle current until the value of the trickle current is decreased to a triggered current value.

Provided are a charging method, a terminal, and a non-transitory computer storage medium. The method includes the following. A charging voltage is detected in applying flash fast charging (FFC) to a terminal. Whether to end the FFC is determined according to the charging voltage. FFC is ended and a standing duration is recorded, where the standing duration is indicative of time which has elapsed after charging of a terminal is ended. A preset safe current is applied to the terminal, when the standing duration is longer than or equal to a preset threshold duration.
