I assume Oscarino is outside the US?
My ipod charger says:
input: AC 100-240V
AC Input: 0.15A Max
Output 5V [line and dash symbol] 1A
Is this the same as yours? (ipod chargers should all be the same since you just change the plug, right?)
Anyway, I just tried before and it worked (light was amber). I only tried for about 5 seconds since I didn't really need to charge it, but I think it should be okay... Don't think the kindle'll explode... lol
