Description

[0001]

Technical field

[0002] The invention relates to the field of charge and discharge, in particular to a mobile power supply, a charge and discharge system, and a charge and discharge method for the charge and discharge system.

[0003]

Background technique

[0004] Users often connect one end of the adapter to the mains and the other end to the electronic device to charge the electronic device through the mains power; or connect the computer and the electronic device through a data cable, and charge the electronic device through the computer in the power-on state. However, the user cannot obtain power from the mains or the computer anytime and anywhere to supply electronic equipment, such as when the user is doing outdoor activities. Therefore, the application of mobile power is born. The mobile power supply is small in size and easy to carry. Users can provide power to electronic devices anytime and anywhere through the mobile power supply. However, we usually enco...

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] see figure 1 The charging and discharging system 1 includes an adapter 20 and a mobile power supply 30. When one end of the adapter 20 is electrically connected to the mobile power supply 30 and the other end is electrically connected to the power supply 10, the mobile power supply 30 obtains electric energy from the power supply 10 through the adapter 20 for charging. The mobile power supply 30 can output the stored electric energy to the electronic device 90 connected thereto. When the mobile power supply 30 is connected to the electronic equipment 90 and is connected to ...
