Problems solved by technology

[0002] The existing mobile power supply generally uses a 5V1A power adapter, the largest is a 5V2A adapter, and the maximum output power does not exceed 10W. Most mobile power supplies on the market use the Micro USB interface to charge the battery. More than 2A) limit, the common use is 5V1A current, the input power is only 5W, the maximum input power of the special is not more than 10W, and the current mainstream capacity of the mobile power supply is 10AH (36WH) or above. If you use a 5V1A adapter to charge, you need 8-10 Hours, even with a 5V2A adapter, it takes more than 4 hours to charge, and it takes longer for a power bank with a larger capacity

Abstract

The invention relates to the field of power generation, power transformation or power distribution, in particular to a rapid charging method and a rapid charging device of a portable power source. A power adapter is connected with the portable power source by virtue of a USB (Universal Serial Bus) data line. The method comprises the following steps that A, a microprocessor of the power adapter comprises a voltage waveform received in the USB data line with a voltage waveform stored in the microprocessor and then outputs different voltages; B, a microprocessor of the portable power source judges input voltage change of a MicroUSB socket, and adopts different charging modes. The used power adapter and the portable power source are matched, the used USB data line is a standard data line, and the power adapter can be a direct current power adapter or an alternating current power adapter. The rapid charging method and the rapid charging device have the beneficial effects of short charging time and reduced waiting time of a user.
