Fast charging
It's lightweight
Durable, I've dropped it a few times, been in damp environments, etc. and it works like new
Recharges relatively quickly
Maybe just the capacity, but I was buying it as a backup powerbank for my pocket

It saves you from having a phone with only 2% battery, but even the iPhone 13, which doesn't have a big battery, won't charge all the way up. The power bank gets quite hot when in use, but it is really compact, so for the price I bought it for in Alza, there is no point in complaining. A great helper when you need to quickly save your phone or IQOS from running out of power - it doesn't charge to 100%, but it got the iPhone 13 up to about 60%.

For that price (within Alza days for 138 CZK) you cannot expect anything better. I needed a small powerbank to power the LED strip and it accomplished what I wanted. Perhaps the charging could be a little faster.

Price - I bought it on sale for 142 CZK
Ideal as an emergency power bank for your backpack
Size
Nowadays of course Micro-USB is not optimal, but for the price ok
It's stupid to buy it for more than 200-250 CZK
Only 10 W of power
