Q: Will this work with an IPad 4?
A: Yes, that would fine & should compatible.
Q: Is this compatible with an iPod touch 5th generation?
A: Yes, should be okay...
Q: Does this work with an iPad 2?
A: The Rocketfish adapter worked with my iPad and it's the original (1st generation). If it worked with mine, and since its older than yours, I believe it should work with your iPad 2. Hope this helps! P.S. This charger is great, since it charges just as quickly as the original Apple adapter I had that came with it.
Q: Does this cable work with an iPod Nano Second Generation?
A: don't think so.
A: Just measured it with a measuring tape. The Rocketfish cable is 41 inches, not including the connectors. My original iPhone cable is 39 inches, not including the connectors. I bought the Rocketfish charger as a spare and now I like it better than my original one.
Q: Does it work with iPhone4S?
A: No. 5 or higher
