I've been so used to slow phone chargers ever since I got the first gen iPhone way back when. Nearly 10 years later, I now have a Moto X Pure that came with a fast charger. Wow! What a difference!
Before, when my phone was about dead, it was basically time to halt usage and drop on the charger for...hours. If I knew I was going out, I knew I better charge that sucker all the way, which literally was a good chunk of the day. With these Turbo Chargers, if I kill my battery from hotspotting all day while running GPS and Spotify and/or way too much Pokemon Go (tho that game is dead to me now)... I just plug that sucker into the Turbo Charger and BAM, within 30 minutes, my phone is basically 100% again.
Sadly this phone does not support Qi wireless charging, a feature my beloved Nokia 920 had. The future is almost here.
