Abstract
The invention provides a portable power supply with additional arrangement of a U-disk function through slight change of the circuit without changing structure or increasing cost. When charging is performed, electricity is taken from a computer USB socket so that data can be downloaded from a computer to the U-disk of a discharge port when the portable power supply is charged via a charging port. When discharging is performed, the data can be uploaded to a mobile phone from the mobile phone U-disk of the charging port when the mobile phone is charged by the discharge port. The portable power supply is dual-purpose so as to be a necessary accessory for the mobile phone.
Description
Technical field
The present invention relates to a kind of portable power source, especially do not change structure, do not increase cost, only slightly change the portable power source that circuit can increase mobile phone USB flash disk function.
Background technology
