Tanjid (Cmf) hi! I use and post a lot about the Anker Nano 3 (511). I get about 25W continuous charge with it and am very pleased for the price I paid (£10 shipped in the UK). I think it charges the CMF1 from empty to full in around 50 minutes.
It also charges my NP3 in about the same time as the charger seems to max out around 25W with the NOTHING phones. It’s tiny and also taken very little space (it’s about the same size and the UK wall socket footprint.) I have tons of phones of it charging in my uploaded images gallery here.
