This powerbank is one that, whilst basic, will do the job. First, I have to say that this is the most aesthetically pleasing external charger I own. The rubberized woven cover is a nice added touch that keeps a smooth polished unit from slipping through your fingers. The size is also reasonable. Whilst larger than a stick charger, it is still far lighter than many comparable units. I was able to fully charge my iPhone 6 from a dead battery, but it took a little longer than with another charger with a more powerful output. Of course the price point on this one is far more reasonable, so it's a matter of what's important. I do love the integrated protection from overcharging--definitely a bonus.
Overall, a sound device that delivers!
