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
