Man Finds Sand In His Tecno Powerbank (Photo)

He wrote :

"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."
