Probably one of the best innovations in mobile tech in the past few years has been the adoption of quick charging. Samsung, and Qualcomm both have their own versions of it, and so does Intel with ASUS' Zenfone 2. Motorola bundled their own quick charger with the Motorola Droid Turbo and Nexus 6 late last year. The same quick charger that cost everyone else $35. The Turbo Charger is a pretty big charger, but does charge your phone pretty fast, which is definitely an upside. Right now, Groupon has the Turbo Charger for just $9.99. The sale is only good for the next 2 weeks though, or until they are sold out.
