I bought this to plug it into the wall and then conveniently charge six devices for my family in one place. However, the wall converter doesn't put out enough power to charge a new iPhone 5 or iPod, or the new smaller pin adapter for the iPhone and iPod won't let enough energy through. I say this last point since an older 30-pin iPad of mine charged just fine, even with a Jambox and a Galaxy phone also plugged in at the same time.
Net, if you want to plug this into your computer it will probably work fine since you won't be using the wall adapter. Also, it looks great and is really slim/space saving. However, if you want to plug it into the wall and charge a relatively new apple product, according to my experience and the guy I worked with at the Apple store where I bought it...choose something else.
