PortaPow special 20AWG 2m Quick charging cable Micro-USB for Android / Blackberry / HTC One / Google Nexus / OnePlus One (accessories)
I've been using my Nexus 7 2012 at the car and the tablet has discharged despite adequate charger. Despite that I use the 2m variant what a USB cable already is very long, the Tablet invites (brightest Navi, music and video) even at maximum load.
