The answer is what does the cord you use to charge your phone have at either end look like? If the end which connects to the charging source is a USB connection then it should work because the other end of the cord attaches to the phone I hope this helps. In other words, if you can charge your phone off of your computers' USB connection, the radio will charge your phone as well.
They don't give a list. What you do is register your radio, during the registration process they will ask what phone you have and send you the correct usb for your phone. For newer cell phones, they all now have the same mini charging port! Great idea.
Ive found that you cant actually get the crank speed consistent long enough to actually be able to charge either my ipod touch or my samsung stratosphere. I think its best used as a crank radio and not as a phone charger
