[0041] Exemplarily, when the charging cable 4 is connected to an electronic device such as a fan or a power bank, the charging cable 4 is only used for charging.

[0042] It should be noted that the charging cable 4 is electrically connected to the circuit system 5 . The charging cable 4 may be directly connected to the circuit system 5 , or the charging cable 4 may be indirectly connected to the circuit system 5 .
