    If you could find one, it would probably cost more than replacing the entire charger.

    i'll get 5V output but what about the current

    You will get up to 1A if you have a proper heatsink.

    cool so instead of that xl1509 i'll use 7805 voltage regulator with heatsink and two capacitors

    how hot do you think it will get if i use it as car charger?
    would it melt the plastic case of the original charger if i put it inside?
    what about NCP 1117 which would be better for such a use?
    will it be better to use premade switching voltage regulator module like LM2576?
