Yes you can use your Kindle charger for your phone. I do it all the time without any problem. We have 4-5 mini-usb chargers on a power strip for our phones (motorolla, samsung, HTC) and 3 different kindles. We interchange them all the time, and have done so for more than a year, without any negative affects on any of the devices.
