Review (5/5): Effective and Fast
Fantastic charger - hits the QC 2.0 amperage guidelines, and will charge a Moto X to nearly full from 20% in about 30-40 minutes. Be sure you're using a cable that will support it, and just check that your phone gives you the "Turbo Power Connected" pop-up. Below is an older review - my first one appeared to be defective, Anker reached out to me and shipped a replacement. 5 star product, 5 star customer service.
When it works, this is an excellent charger. The one gripe I have with it is that it seems to need to be unplugged and plugged back into the wall for the quick charge to kick in (tested with different cables). The non-QC ports charge quickly as well, and it has the typical Anker high quality feel to it.
