DivakarKadupu Dash/Warp are based on VOOC tech which is used by BBK companies.
The QC 3.0 charger that he has will charge faster than VOOC chargers.
No doubt a 45w PD/PPS charger will charge faster, but my suggestion was to use the 33w QC 3.0 charger that he has instead of wasting ₹2000 on a new charger just for the sake of 15/20 minute faster charging.
Its up to him to take the suggestion or not.
