Thanks to the large capacity, it charges the mobile 0-100% 3x in my experience
Charges very quickly when using a quality cable
Quality plastics used
Fast charge indicator
Included cable, but I don't expect fast charging
Slightly heavier
When you squeeze the sides, something inside peels off, I didn't get a great feeling from it
Display not readable in sunlight
Makes noises when charging quickly, but I think it's normal for how fast it charges
Heats up around the connectors, again when using fast charging

po roku a pol obcasneho pouzivania uz nefunguje jeden usb-c port ani s kvalitnym Alza kablom, ked powerbanka hlasi 25% kapacity vybije sa extremne rychlo. podstatne rychlejsie nez za nova.

A crack began to appear around the perimeter of the cover and the power bank inflated slightly

Already second piece purchased, first one (10Ah) went to extreme heating and random shutdowns, with this piece (20Ah) the display does not turn off. Bought during a sale, so a lot of music for little money. Alza dealt with the complaint of the first piece and settled it within one day.
Large capacity
The prehistoric micro USB is no longer here
Charging speed
After some time the display stopped turning off, so it lights up permanently and cannot be switched off
