UGREEN 130W USB C Car Charger 3-Port PD 100W PD3.0/QC4.0/PPS Fast Car Charger Adapter+ 100W USB C Cable £25.99 using voucher @ Amazon/Ugreen

A really decent car charger from Ugreen. Comes with a proper 100W cable as well, so this should be enough for most of us.
I don't think this would be much cheaper even from China via Ali. Via Amazon, you will have proper warranty as well.
