An electric power adapter for portable electronic device is composed of an adapter cord with both connectors at its both end for respectively connecting to the said portable electronic device and a data memory unit, the data memory unit for storing the power supply data of the said portable electronic device, and an electric power converter for converting the voltage the the value needed by the said portable electric device according to the power supply data.

Description

technical field [0001] The invention relates to a power adapter device, in particular to a power adapter device applied to a portable electronic device. Background technique [0002] With the thinness, shortness and diversification of electronic products, many portable electronic products such as mobile phones and digital personal assistants need to use rechargeable batteries as their main power source, and can directly use the charging power of portable electronic products. A circuit is used to charge the rechargeable battery. Manufacturers usually provide a power adapter to convert general AC power into regulated DC power for portable electronic products. Take mobile phones as an example, such as figure 1 As shown, the manufacturer usually provides a power adapter 10 (commonly known as a travel charger) for use with the mobile phone 11, but since the battery specifications used by the mobile phone 11 of each manufacturer are different, the power adapter 10 of each brand ...
