hmm, I actually been charging my NP2 with a wireless charger and the phone doesn’t even get warm, even more when I compare it with my work phone (iPhone11) that gets warm. But even that, it’s warm, not HOT.
It’s a matter of choice. I hate cables, so to have the possibility to just put down my phone and having it being charged is nice for me.
As for the charger itself, I’m using a 15w one from Samsung
Hope this helps
