How do I charge a iphone 5

Take the unit back for assistance or replacement.

The Memorex is a player only. It does not have the ability to sync, that is, to exchange files with the iPhone. It should be able to play music already saved on the iPhone, however.

Yes, with the help of a 30 pin to lightning adapter. I found one at rakuten.com for under five dollars.

I have a I live soundbar that I cant figure out how to turn the alarm off

Sounds like an issue with the clock radio, some generic charges won't work with iphones either.

Click the Download Tab and you'll see a pdf manual.

Your iHome may be an older model with an the wrong charge type. Different iPhone / iPod generations use different charge voltage with iPhone requiring a higher voltage than your iHome gives. My suggestion would be to get an adapter that should fix the problem.

Just solved exactly the same problem by powering off and on the iPhone

nope...there is nothing u can do..sorry.
