Powercore speed 20000 PD isn't charging past 50%

Im charging my powerbank for the first time, when i got it, it was completely discharged and i plugged it to the Samsung’s charger over night and today its still flashing the second LED
Should I be concerned or its normal for the first charge to take that long?

Hi @Mohamad_Khrubi I would avoid using a Samsung charger for recharging as these are adaptive chargers designed to adjust its power output based on what a Samsung phone would normally report it requires.

I would recommend you use a Anker PD wall charger such as the following;
