Not verifiedGoogle lists only 'Fast charging' and publishes no wired charging rate or charge time; its footnote says fast wired charging rates are based on the Google 45W USB-C Charger (sold separately). The UK configuration page's charger label says this SKU supports USB PD chargers with power minimum 7.5 W and maximum 27 W (charger not included). That is charger compatibility, not a charging rate, so the value stays unknown.
