Electronic device and method for charging battery based on a plurality of power sources
First Claim
1. An electronic device, comprising:
- a housing;
a battery disposed within the housing;
a first interface electrically connected to a first external power source;
a second interface electrically connected to a second external power source; and
a circuit electrically connected to the battery, the first interface, and the second interface,wherein the circuit changes a first voltage output from the first interface based on a second voltage output from the second interface, changes a first current output from the first interface based on a second current output from the second interface, and charges the battery based on the changed first current and second current.
