A:AnswerYes. It is both. You can either use the buzzer or the AM/FM radio to alarm you if your iPhone isn't plugged in. Take note that the display is bright, even after you have turned the dimmer to its lowest setting. Something to think about when you're trying to sleep at night.
A:AnswerSee my review. My older (2nd generation) iPad has the larger 20-pin connector. If you have a newer iPad with the 9-pin (I think) connector that will work on this unit.
A:AnswerThe connection is the new 1/4" wide Apple one, not the older 1" one. So your iPhone 7 would work, but not the 1st gen iPod, and probably not the 4S.
