Hello!
Yes you could always use a charger thats rated 5V 2A. This will not damage the device. However just be aware that your charger has to be DC, not AC.
When your device says 5V 2.0A 100VAC, then this could be harmful to the device, as it runs of DC power, not AC power. You need to find a charger that outputs 5V DC.
