    NONE of the 10 chips worked correctly. When I put load on them, something inside the chips collides and the output voltage jumps to the input voltage. After that the chip does not regulate any more. Output voltage = input voltage. Very bad quality !

    Everything's working fine. I didn't test the max amperage, but it holds 2 amps very well.
