Stoffe hi fabric.
I user an Anker Nano 3 (511) 30W charger and get 25W on my CMF1. It was £10 in the UK and they sell globally.
You need any PD3.0/PPS charger, not necessarily a NOTHING charger (which I haven’t seen push 33W in any confirmed independent test.
25-28W might be the best the phone pulls.
Note that not all PD3.0 chargers have PPS, so look for that spec in any charger. I looked around US/EU and found the PPS-enabled charger I mentioned to be the best for the buck.
