> My default charger is a 96W charger which is a fast charger. Fast charging as we know is not good for the battery. I have tried with a 35W charger, but that is not sufficiently high enough to charge the battery and run the machine.

You cannot manage the amount of current flowing from the charger; this is **not** how this works.   First, current is drawn, not pushed.  The device (MacBook, iPad, iPhone, etc.) negotiates with with the charger to deliver what it’s asking for.  Secondly, the wattage rating on the charger is the *maximum* current output, not what it delivers all the time.   Your 96W charger could be outputting just 3 watts at any time.
