I am very satisfied with the power bank as it serves its purpose. I can highly recommend it.
Reasonable price, charges the phone battery quite quickly. So far I've charged 4 Samsung Galaxy phones, S26 ultra, S8, S22 ultra and an S4, and it's still at 50% battery, so I'm happy. It's obvious that the power bank's capacity will decrease over time with use.

I recommend it. I'm going to get another one.
Small and has a plane symbol so it's great for travelling.

Fast charging (phone)
Fast power bank charging (under 3 hours)
Small capacity
It charged a battery with a capacity of 4500mAh three times, so instead of the declared 20000 capacity, it's more like 14000.
