Charging method, electronic equipment, system and computer storage medium

The invention provides a charging method, an electronic device, a system and a computer storage medium, the system comprises a first device and a second device, the first device comprises a boost chip and a first battery, the second device comprises a charge pump chip and a second battery, the first battery is used for outputting a first voltage to the boost chip; the boost chip is used for receiving the first voltage and outputting a second voltage to the second device, and the second voltage is greater than the first voltage; the charge pump chip is used for receiving a second voltage and outputting a third voltage to the second battery, the second voltage is M times of the third voltage, and M is a positive number greater than 1; and the second battery is used for receiving the third voltage and charging. According to the system architecture, the power of wired reverse charging can be effectively improved, and a fast charging process in a general scene is realized.
