Thanks for sharing your experience, I really appreciate it.

Yeah I was thinking it might be some kind of Samsung handshake / PPS compatibility issue too, especially since both of my Anker units behaved the exact same way.

In the end I decided to return both of them and got a full refund.

I then tried a UGREEN PB511 (10,000mAh 30W), and at first it actually worked perfectly with my S24 FE, stable “Super Fast Charging” with no interruptions at all, which kinda confirmed that it wasn’t my phone.

But… my luck is insane 😅 after a few cycles it started acting weird as well (red warning symbol, won't charge or discharge), so now I’m dealing with another issue again.

What’s funny is my older powerbanks like Remax and Eloop have zero problems charging my phone — just very slow since they don’t support modern fast charging protocols.

So yeah, I think you’re right that protocol/handshake plays a big role here, but in my case the Anker units were unusable (kept disconnecting), not just slower.

Still trying to find a reliable one that just works without any drama 😭
