Ather DOT/portable charger service/maintenance

I have been using portable charger for 3months now, i see the cooling fan has dust accumulation, How to clean it? Is there any option to give it at service centre along with Ather for service and cleaning. My notices on portable charger:

  1. Dust accumulation on cooling fan

  2. Ather Connector side rubber attached to brick turning into black powder

  3. While carrying in boot, one screw cameout, they were marked in blue for warranty i guess.

@abhishek.balaji Please note.

If any owner has tips for better charger life ping here.

I think it is better charge at evening or night, compared to noon, and charging gap when charging more than 3hrs if possible.
