Query: Works properly now.

At first, the red light charging indicator did not work in my car even though battery was getting charged. I thought the problem was with the indicator. But when powered on wall socket, the red light appeared. Then after subsequent uses, it started working properly in the car too. Could have given 4.5 but now that I don't have any problems with it, I will give a 5.
