I guess I need to be the one that says any manufacturer's USB cable that works at all should be able to do at least 1 amp charging. USB spec is .5 amp, so that isn't surprising. Laptops that don't recognize something plugged into the port may not send the full voltage in order to save power, it depends on the manufacturer. The stock cable should easily handle 2.1 amp.
In short, the problem is much more likely to be the charging adapter or the USB port not putting out enough voltage, not the cable itself.
At least its not Apple which requires you to have iTunes installed to charge iDevices properly off of a USB port.
