Abstract

The invention belongs to the technical field of charging, and provides a charging device of electronic equipment and a power adapter of the charging device. In the process of charging a battery in a conventional charging mode after the power adapter is powered on or resets, when the output current value of the power adapter is within the conventional current range at a preset time interval, the power adapter is in quick charging inquiry communication with the electronic equipment; after the electronic equipment sends a quick charging instruction to the power adapter, the power adapter adjusts the output voltage according to the battery voltage information fed back by the electronic equipment, and when the output voltage meets the quick charging voltage condition preset by the electronic equipment, the power adapter adjusts the output current and the output voltage to charge the battery according to the quick charging mode, and therefore the purpose of quickly charging the battery to shorten the charging time is achieved.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a charging device for electronic equipment and a power adapter thereof. Background technique [0002] At present, the battery of electronic equipment is charged through its power adapter, and the adapter usually uses a constant voltage output method to charge the battery, but for a large-capacity battery, charging the battery through a constant voltage output method will cause the charging time to be too long. Long, so the above-mentioned prior art can't realize fast charging to battery to shorten charging time. Contents of the invention [0003] The purpose of the present invention is to provide a power adapter, aiming to solve the problem that the prior art cannot realize fast charging of the battery to shorten the charging time. [0004] The present invention is achieved in this way, a power adapter, the power adapter is connected to the communication interface...
