Customer Review

Of all the external battery with whom I had to do so far this is the best.
He invites devices very quickly, just like the Power IQ chargers from the same manufacturer.
The only criticisms are the very long charging time of the battery itself (14 hours or so) and cheap piano black plastic at the ends of the battery. But that is not enough to draw a star.
