Sony Xperia XZ Premium Charging charge??
Hi @Ulubey1, welcome to our forum!
This looks to be a product from Sony Electronics and this forum is only for smart phones, tablets and some accessories, so you may want to double check with them if this power bank is made for charging smart phones, or if it has other areas where it's supposed to be used.
You can get in touch with them on the link below.

I hope that helps and have a nice day!
