"My power bank drains rapidly. Charging it takes up to 6 hours, but reverse is the case when using it. Doesn't even last up to an hour. So I decided to open it. Alas! What I saw was alarming."
"I opened it and saw four blue-coated cells. Two was connected, but the other two wasn't. Worried why the other two wasn't connected, so I took one and broke the blue-coat, then opened it."
"Alas! The cell was filled with sands."
