Varies depending on conditions.
Note:
The actual charging current of USB charge varies depending on the system conditions. It will be as follows.
[Each VBUS limit current] – [Current consumed by the system] = [Actual charging current]
[Each VBUS limit current] – [Current consumed by the system] = [Actual charging current]
