家园 可以达到1800mA

Standard USB hub ports can provide from the typical 500 mA [2.5 W] of current, only 100 mA from non-hub ports. USB 3.0 and USB On-The-Go supply 1800 mA [9.0 W] (for dedicated battery charging, 1500 mA [7.5 W] Full bandwidth or 900 mA [4.5 W] High Bandwidth), while FireWire can in theory supply up to 60 watts of power, although 10 to 20 watts is more typical.

查了一下典型数码单反EOS 60D使用LP-E6电池,容量是[email protected]

充电功率没问题,就是电压有差别(USB充电电压是5V)。
