I have one of those in the box but after finding out that they do not put out a constant 5V and can go as high as 6V, its still in the package.
i am NO expert but how can a unit that only holds two batteries generate 6v or even 5v???? two regular AA, which i believe the Energizer takes are rated at 1.5v each. quick math shows me that is 3v. so not only will it NOT fry the unit it will NOT fully charge it either. wouldnt it be the four battery USB chargers that you have to be leary of (1.5v x 4 = 6v). you either need one with a voltage regulator or use those 1.2v rechargeable batteries. like i said, i could be miss understanding this though. later. .
