OK. I have two charger and they both seem very stable.
(A) Anker 511 (Nano 3 30W) PPS-equipped. I started around around 45% and after 60% it started to slow down as it should. I never get more than 24W out of it but it’s very stable.



(b) Anker Nano II (65W) not PPS-equipped. I get around 50W max out of it. Here I charged from 70% and when I plugged it in went well over 30W and then started slowing down at 80% like it should.


Because I’m a dork, I’ll going to try and drain my battery while doing some other work tonight and test the Nano II 65W charger.
I don’t see any inconsistency in charging with three two chargers but I admit that it’s not a fully complete test and post to the forum later.
