Yeah that'll fuck the performance up bigly.
I'd say 64W minimum. I'm on 72W myself (barrel jack, TS100 so no USB-C), more is obviously better.
Wattage is basically just the total amount of heat output your iron can do, you're artificially limiting yourself to less than half of what it can do with a 30W brick. Also keep in mind if there's a wire inbetween, it needs to be compatible because USB-C is retarded like that.
