Ok so ive searched the threads and nothing has really come up.
I need advise on what the best car charger is for this phone as there are a few issues to lay out which i mention below

• The device power draw on the quad core and gps is high. if charging via pc it doesnt charge unless its sleeping. i believe usb is 500ma
• most car chargers provide 500-1000ma however the official samsung one is only 700ma
• There are some 2100ma chargers but im not sure what that would do to the device

with that list can people give advice on successes they have had using gps in the car without losing battery life with this device
