G+_Jon Reeves Posted January 20, 2014 Share Posted January 20, 2014 Are there CAR USB power supplies that put out lotsa amps? I was using my #Nexus 5 in the car and had the case where the battery was draining even though I had it on ships power. The USB charging cord and lighter adapter power supply I used were the Samsung one that came with the Note car docking kit. I had Bluetooth and Wifi on with AT&T LTE and running Waze and/or Google Maps Navigation. I was careful to have no other apps running. I was using WiFi hotspot to get my Nexus 7 online. Later when I was getting warning that the battery was down to 4%, I turned off WiFi and the battery started charging. It was 35% charged by the time I got home. I had left the house with the battery dead and brought to life in the car. Does a car adapter like this Anker 24W do a better job? Are there even heavier ones? I guess the most you can charge is 4 Amps, even with the OEM power wart? http://www.amazon.com/Anker%C2%AE-USB-4-8A-Dual-Port-Charger/dp/B00D82O68Y/ref=sr_1_2?ie=UTF8&qid=1390197150&sr=8-2&keywords=anker+car+charger Link to comment Share on other sites More sharing options...
G+_Steve LeMoine Posted January 20, 2014 Share Posted January 20, 2014 Ryan R. Is right. To protect the battery it will only draw so many amps. You don't want it any other way or you would damage the battery and maybe the processor too Link to comment Share on other sites More sharing options...
G+_Stan Ho Posted January 22, 2014 Share Posted January 22, 2014 The problem with a lot of car charger is that the data pins are not shorted so the device is sensing USB charging if you Google a power cable with the data pins shorted this will fix the issue with charging Link to comment Share on other sites More sharing options...
