    Terrible battery, when I needed it, it never stayed on long enough to fully charge my phone or iPad. I thought it was the placement of the on off switch, but maybe I got a lemon.

    it charges... just not fast enough.. we should have looked at the specs a little more before buying. We assumed bc it was from the energizer brand that it would go fast but yeah.. it only offers standard charging.
