Iphone 11 charge with powerbanks is it okay?
Im using mi power bank fast charging fir charge my iphone is it okay for battery health of my iphone
I've charged my iPhone many times using a battery pack. I use Anker batteries because I know they are good quality..
I also have a smart case from Apple, which is the same thing as charging with a battery pack.
In general it should be just fine. I personally would not do it with any ol' cheapo brand battery pack that I haven't heard of before. But most of those are probably just fine as well.
Here are a few support articles regarding iPhone batteries/performance if you're interested

I would also say that you should not regularly drain your battery. ie, if you let it get down well below 20% every day.
I will always plug mine in if it gets down to 20%. I've had my phone for a year and it still says 100% health
