Unless a USB charger goes over the recommended 5 Volts, you're not going to screw up anything. Current (Amps) are like a meal, you can't force it faster than the mouth (device) is willing to take it in. Voltage, however, especially when it's on the higher side, can kill the device. Now, where the mains to USB chargers fail is internally being configured incorrectly. If it's not wired correctly internally, the device (PRS-650, in this case) will see the charger as being a USB port on a computer and limit charging to 500mA. If wired correctly, it will charge at the full rate, say 1A (just an example).
