iPhone 12 pro. Power bank not working

[Rorosbutt]

I have a power bank that’s a few years old that I’ve been using. The 12 pro won accept the power.

iPhone 11 Pro and iPad accept power without issue.

whats going on? Anyone else have this issue?

That’s weird. Maybe it’s 5w or less power delivery coming from the powerbank. Im speculating the 12 is a power hog since iPhone X/xs/11 need 18w to fast charger 50% in 30 mins now the 12 needs 20w to fast charge to 50% in 30 mins. All speculation until some really rest this. I don’t have a 12 pro max yet but I hear iPhone 5 watt charger take a long time to charge now.

works fine on 11 pro. The 12 pro just doesn’t work at all, 50% or >85%.

is it a USB-C PD?

is it a USB-C PD?

No. It’s lightning.

I believe the issue is that it cannot put out more than 5W. The 12 pro seems to have a requirement that it only accepts power if it’

I got one that is able to put out 10W and works fine. Something to note.
