But now the bad .. me during I guess 20 charging by chance when look noticed that the housing is deformed to the touch I noticed that the Power bank was hot at the top.
Since I have a little idea about the built-in battery that thing I knew it would be foolish to simply leave to cool this thing to not know whether the Power Bank continue stewing and possibly. The built-in battery will explode.
So I quickly to the USB connector side of the lid away pulled out the electronics and the battery separately from this. Although this warranty is gone but I reassured them. But I have to say that one. The thing rather far away safely covered or refractory including himself should leave because it's just too dangerous to cause eg a short circuit
