I once watched a video of a man holding what looked to be a bicycle battery walking into an elevator. After the doors closed, it seemed to have exploded and burst into flame in his hands, and the aftermath was charred remains.

After seeing this I refuse to sleep near my 20,000 mAh power bank. I saw this Jackery power station for sale for an ultra discounted price and noticed it was not lithium iron phosphate and I noped so fast.
