Millet 33w is of course worse than 55w price ratio!
Because the latter supports 55 watts of charging power, while the former only supports 33 watts of charging power, the former's charging efficiency is far less than the latter, so it charges more slowly.
With a 4000 mah mobile phone to charge, the 55w charger can be fully charged in only half an hour, and the 33w charger can be fully charged in an hour
