This driver was designed to be used with USB port charging. And, I was always under the impression that a standard PC USB port can put out 1A. According to the information I have found at Wikipedia

Quote:
In Battery Charging Specification, new powering modes are added to the USB specification. A host or hub charger can supply maximum 1.5 A when communicating at low-speed or full-speed, maximum 900 mA when communicating at hi-speed, no upper current limit when no communication is taking place. A dedicated charger can supply maximum 1.5 A of current. A portable device can draw up to 1.8 A from a dedicated charger. The dedicated charger shorts the D+ and D- pins together and will not send or receive any information on those lines, allowing for the creation of very simple, high current chargers to be manufactured. The increased current (faster charging) will occur once the host/hub and devices both support the new charging specification.
I could be wrong, but this leads me to believe that the USB port can handle it.
