    Does anyone have the issue of the Powerjolt SE car charger being extremely slow to charge the iPhone 4?

    To be honest, mine just stopped working altogether. :(

    It was a little slow with my 3GS though, which I think is normal for car chargers.

    Can anyone recommend me an Apple endorsed car charger that is half decent and charges at similar rates to the wall socket?

    I dont think this is possible. The wall socket voltage is much much much higher than any voltage your car battery could put out. Use a car charger as a "crutch" to pull you through while youre on the road and as soon as you get into your destination, plug it in to a real socket.

    Is charging slowly via a car charger an apple only issue or do all smartphones charge slowly? My nokia 5310 charged at the same rate as a wall socket charger?

    To give you guys an idea of how slow the powerjolt SE is at charging my iPhone 4, in 5 hours it charged only 37%. This however was while using turn by turn gps navigation at the same time. Is this normal?

    No, my car charges my laptop while I'm using it faster then that :p While you're driving, the car should be able to charge it at the speed of a wall charger, only while stopped do some cars lower the voltage to prevent the battery from dying

    I have this same charger and actually notice it charges faster than my previous D-LO charger did. Did run into an issue with a faulty fuse however Griffin replaces the unit and now it works great.....for now.

    iPhone/iPod car chargers can charge at three different rates.

    iPod car chargers - 500mAh
    iPhone car chargers - 1000mAh (1amp)
    iPad car charger - 2100mAh (2.1amp)

    I remember my old Griffin powerjolt was an iPod one that supplied only 500mAh, I changed over a generic 1000mAh and now it charges VERY quickly (equal to the wall charger which puts out 1000mAh also)
