samgada Phone (2a) can charge up to 45W
Even if you take a 65w charger, it will only be able to charge up to 45W
a “PD” charger will have various voltage/ampere profile to reach the max supported configuration for both device (adapter and Phone) so the only thing you should get is a good “PD” charger (Belkin should be good) and a good USB-C cable such as the one in the box.
