is a less expensive than Google's charger.

The charger that Jack recommended above is more expensive, yes, but it also is far more capable. At 65w it can power smaller laptops, your phone, and maybe even a watch or earbuds at the same time.

That being said, the charger I linked would seem to fit your criteria for something that is a less expensive PD charger for your phone alone.

Anker makes some good stuff, this charger will charge at the full 30W and is compact: https://www.amazon.ca/dp/B0B2MM1W65?ref_=cm_sw_r_apin_dp_8AQXG1QWSG98S2MR1M6Z
