No. A standard USB port on a PC is rated for 500mA and the Kindle will charge from a PC as per Amazon's specifications. Amazon don't even bundle the charger for everybody. If you plugged the Kindle into a USB hub then you'd get less than 500mA. Assuming your USB port/charger isn't faulty and isn't badly made then nothing will be damaged as devices have to be able to accept these variations in voltage and current to be certified as a USB compatible device.
