Anker Soundcore Life Dot 2

I am by This Week Anker Soundcore Life Dot 2.But Chrging case indicator not working .how do i know if my charging case charger is working.i am using Samsung Mobil charging adapter (5.0v- 1.55A) please help me

The white light that comes on when you plug it up is the indicator. Once fully charged the light then turns off. I think the new tech was great creative thinking in my opinion. No blinking lights nomore😀

Same thing here, no lights on the charging case
