    Charge time is shorter than you would think. I can plug my phone in at less than 10% and use it all day and still end up at 100% and the anker still has juice.

    A little large (about the size of a phone by itself) but definitely has enough capacity to charge my phone multiple times over.

    I'm an Anker fan, works great and didn't leave me hanging. I use these to provide power to my cameras and digital audio equipment when recording concerts. Reliability is a must.
