Powering WiiM Pro Plus with a power bank

I doubt it, but do what you want.

I'm careful if you doubt it.

I don't understand that.

(Note: I literally didn't understand the previous post when it wasn't translated to English, yet.
Cannot say I understand the meaning of the translated text any better. )

Me too nothing and nothing.

There are some blurry pics on ASR somebody did a teardown.
I have a pic here from somewhere else View attachment 6632

In my case, from linear PSU to deep-cycle battery. Happy with the sound.

Yes, but what will happen to the workers?

It just hard to imagine how power supply can alter sound. You’re just making linear power supply relevant to stay in business.

Hi all
This might have been discussed elsewhere - or be common knowledge - but I’ve started using my mobile power bank to power the WiiM Pro Plus. (And then ensuring the power bank is charged up via the mains overnight).
It does seem to sound better! Though this might be my brain tricking me.
Has anyone else experienced this?
Cheers,

My power bank allows me to charge and use at the same time so long as I get the WiiM fired up on the battery first. Not tried A-B with charge disconnected but done A-B using wall charger alone and power bank so far. Not imagination. The bass tightens up. It losses some bloom and effectively can sound a bit reduced. Drum strikes are cleaner and tighter. Vocals sound about the same to me. My knees won’t let me further investigate as the WiiM PP is on a low shelf .

Yes indeed. Many thousands have experienced it. Welcome to the world of Confirmation Bias.
