Charges very quickly
Many ports (USB C, 2x USB A and even micro USB)
Only 4 LEDs show the charge (it's fine but it's not an exact percentage)

The power bank is very powerful, it charges your phone and tablet very quickly. It might even be able to hold a laptop.

I have a 1.3A charger and it's not enough you have to have a good adapter for it
I've had it for four years.
Interesting that 4 years ago it cost 450kč: D
the best power bank I've ever had
can power both phone and headphones at the same time
you have to get a proper adapter or it won't charge
