Lightweight, charging speed matches, I originally thought I would miss the capacitive display, but the 4 diodes fully suit me. And especially light and small as a possible backup for a day trip

A fully charged powerbank will only give your mobile phone with the same battery capacity about 70% of a charge, but it will still serve as a foldable emergency kit.

I disassembled the power bank, it is quite well made. I'm a bit puzzled that the battery in it has a stated capacity of exactly 5000mAh, so the electronics would have to be 100% efficient for the entire powerbank to have a capacity of 5000mAh.
