Charger is my favorite pvp build, but you're wasting your time trying to kill smiters.
If you're quick you can ct in charge once then leave. Rinse and repeat, but you'll eventually lose.
Get a Phoenix charge kb into smite and reset. Once you get a hp lead you can hold smite
Use a full inv of Pcombs. Max ar life over rated on a charger imo. Keep 75fcr most of the times but vs a smiter 30 or 48 is enough. Make up lack of frames with ct
