With the USB power limit being 0.5A for a port, that's an instant motherboard/port fryer, unless you're using a powered usb hub that can provide the current for these.
You can charge under maximum current, just takes longer. Voltage is what matters, hence why usb chargers for phones and mps players etc normally take longer than the equivelant socket charger.
# This cable can be used to connect a PC to a bus-powered external USB device which has power consumption requirements greater than 500mA (e.g. hard drive enclosures, USB 2.0 hubs etc.). # For bus-powered USB devices with power consumption requirements of up to 1A
I have one in my Huawei E220 kit. Until now i wasn't sure exactly why it had two plugs, now i know i can use it for fast charging :D
P.S. now that i'm thinking about it...i wonder if i can get better 3G signal quality and network speed if i pump more current with this cable into the 3G modem. There must be a reason why Huawei included the cable in the E220 kit... I'll have to try tomorrow :)
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
the pic is a wtf though ... 1amp at 5 volts?!!

oh, then i could just use a dual usb cable, like this one:
