Question: Will this charge an iPod Shuffle?
Document: This is a very useful product. I use it to charge my iPad and my son's iPod shuffle at the same time.
My ipod shuffle was taking forever to charge on our PC, which had to stay "awake" to accomplish. The PowerGen wall charger fixed that! Works with ANY USB cable - and works quickly! Well worth the price - if your USB device is not charging quickly on your PC, this product will solve your problem. Another winner from Amazon!
Product is great. I can recharge 2 iPods/iPhone/iPad at the same time. Gave one to my 64 year old mother so she can charge her Shuffle & a rechargeable speaker at the same time. Great for her so she doesn't need to use the computer to charge them. Having BOTH usb outlets out of a single outlet keeps my wall socket free for other devices.A+++ definitely recommend
Was priced right and works fine. Charges my Shuffle and a little speaker quickly. Seems like sturdy build and the packaging was also quality.
I use it to charge my ipod and iPad at the same time. This thing is simple and great for travel.
I just used it 10 or 12 times to charge my ipod and cell phone.And so far so good.
Works great I can charge my ipod and kindle fire at the same time, works with my older kindle also.
This works well. Quality piece, doesn't look cheaply made. My son uses it to charge his ipod and he is very happy with it.
The product arrived sooner than expected and works great to charge my IPad and IPod. I haven't had any problems with it so far.
So glad we purchased this item; infact, we have two. Makes it so much easier to charge ipod, ipads, and iphones!
Answer: I used it for iPhones and IPad. Not sure if that helps any.  Both ports are not made for all apple products though. I can use both for an iPhone 5 but only one would charge an iPad 2 and old iPhone 3G.
