This is completely untrue... did you make this up?
Griffin makes many:
Belkin and Kensington make them as well. Many are now 2.1A for the iPad.
But to the OP - a 1amp charger is not going to fix your problem in most cases. You need a cable with the data pins shorted so that the phone thinks it is pulling power from something other then a USB port.
A USB port only supplies 500mA - the phone will draw a max of about 750mA; but only if it thinks it is not attached to a PC. The wall charger shorts the data connection so the phone knows to pull more current.
I purchased a dual port (1A per port) charger at target or walmart, and then a took a USB cable and cut open the cable and shorted the data wires (not red or white - but the other 2). My phone says it is charging on AC power and charging keeps up with GPS.
It is possible that you could buy a car charger with the cable built in and the circuitry set to tell the phone to draw more then the USB 500mA, but I am not sure.
But know this; if the phone does not say "AC Charging" under settings->phone-> about - like it does when the wall charger is in use; then you are only getting 500mA.
