There are 3 conditions for "supercharging" to work.

1 Smartphone that is compatible and set up for.

2 The right cable for your smartphone.

3 Suitable power supply for your smartphone.

If 1 of the 3 is not taken into account, it will not work.

I myself had the same type of problem and my cable was theoretically compatible but apparently it was either faulty or not compatible with my smartphone because I just took another cable and then it worked.

In your case, if you have the option, it's to change your power supply and/or the cable to see if it would work...
