Description

Adapter device with two-way charging function

This creation is about a switching device, especially a switching device with two-way charging function.

Nowadays, many electronic products must rely on rechargeable batteries to provide power. When charging the battery, you must use the dedicated power supply device or adapter device for the electronic product to connect the electronic product itself and the charging power supply (mains or mobile power). Charge the rechargeable batteries in electronic products. However, for some special electronic products, such as drones, hand machine tools or palm-sized small household appliances, special power supply devices or adapters are still used, and special fixed voltage and special connection ports are provided to charge the rechargeable batteries of electronic products. Therefore, the rechargeable batteries of these electronic products can only be provided for the exclusive use of the electronic products.

However, once the electronic product itself is damaged, the internal rechargeable battery will be able to charge the rechargeable battery because a dedicated power supply device or adapter device must be used to connect the electronic product and the charging power source. Therefore, when the electronic product is damaged Even though the internal rechargeable battery can still be charged and discharged normally, it cannot be adapted to other electronic products, thus becoming electronic waste.
