I use my Nexus 7 in my aeroplane on airnav pro and GPS, in this mode battery life is 3 hours, is there a 12 volt charger that will keep up with this usage ? I have tried 1 amp, 1 1/2 amp. 2 amp and a gorilla battery pack apart from getting warm, not much change
You mean a power pack that can charge as fast as it power is drawn? I use mine on journies as a a satnav and my Anker keeps up but then I normally get more than 3hrs so perhaps your power demands are more than mine?? Mine lasts the journey London->Wales which can be 5hrs or so.
Any other apps running? You on Marshmallow / Android 6?
