Familiarity: I've put it through the wringer
With how much our culture relies on technology and battery driven products, a portable charger can come in handy in so many instances. This one charges fast and also charges whatever it is charging, insanely fast. Comparable to a wall charger. I'd buy it again, this thing is awesome!
