Hi, I'm using Samsung Galaxy Note 3 and Galaxy Note 2 right now. It's original charger is at 5.3V and 2.0A. Few days before I left it at my friend house, and I decided to use my Galaxy Gear S charger which is at 5V and 0.7A. And I just took my charger back, charging and I realized my phone charge very very very slowly (I really mean that slow). Both my Note having the same problem. Even battery percent dropped when playing games. That's my first problem. And the second is, I'm using the Gear S charger to my Samsung Powerbank which is at 5.0V and 2.0A input, and 5.0V 1.8A output. Charged full and my powerbank having the same problem, it won't charge both of my phone. So, is it because I'm using the lower A then my phone and powerbank damaged or something? Is there any way to fix? Like using other charger temporarily? Thank you for helping. I'm so desperate right now huftt.
