Description

[Technical field]

[0001] The present invention relates to the field of portable power supply products, and more particularly to a charging case that allows power indication and charging at the same end. [Background technology]

[0002] Rechargeable lithium-ion, nickel-metal hydride, nickel-cadmium, and other dry cell batteries typically require a charging case to charge.

[0003] Currently, battery cases for charging dry batteries can usually only charge the batteries using a 220V household power source, and cannot charge other electronic products via the batteries, which is a defect that they are single-purpose.

[0004] To solve this problem, Patent Document 1 discloses a portable charging and power supply device with detachable standard batteries, which includes a housing, a PCB board, a positive electrode sheet connected to the PCB board, a negative electrode sheet, and a discharge interface and a charge interface provided on the PCB board, in which a standard cylindrical or rectangular lithium battery can be inserted into the housing and the lithium battery can be removed and used, and the charging case can not only charge the standard lithium battery through the charging interface, but also charge an external electronic device through the discharge interface using the standard lithium battery, thereby expanding the uses of the charging case and expanding the application scenarios of the charging case.

[0005] However, the positive and negative charging electrodes of the charging case disclosed in Patent Document 1 are located at both ends of the charging compartment, and during charging, both ends of the battery need to be pressed into the charging compartment to bring the positive and negative charging electrodes of the battery and the PCB board into close contact. At the same time, when the positive and negative charging electrodes are located at both ends, charging lines need to be arranged at both ends of the charging compartment, making the product structure more complicated and manufacturing more tedious.
