I bought this item for the output characteristics: 5V and 1A because I was looking for this type of article to charge my HTC Desire in the car. I am disappointed because despite the same specifications as my phone charger, this article does not load the device, at most it maintains the load. I put 3 stars because I have not tested with IPOD / IPHONE so I let the benefit of doubt, however, in my use I would put him only 1 single star, I regret the purchase.
