I still have an old Anker 20,000 mAh power bank that works fine. Might not have the same charge ability as it once had but I can still get 2-3 charges out of it for a Pixel 8 Pro. Has 4 LED's to display charge level and a button that flashes them when you want to check status.
I bought a UGREEN bank on a recommendation and it was a buggy mess. It discharged more than it should when charging and when plugged in it rapidly charged to 100% which was sus. Graphical menu was weird and displayed ambiguous graphic messages to avoid text. These things feel like time bombs.
