That night, the moonlight was hazy and everything was quiet. I sat alone at my desk, facing the screen, my fingertips jumping on the keyboard, immersed in the final sprint of an urgent project. The night outside the window seems to silently accompany me, but the dim light inside constantly reminds me that the battery is quietly running out. Just as I was about to end this night of fighting and search for a moment of peace in my dream, a thought flashed through my mind - why not recharge my phone? What if there's something urgent tomorrow morning?

So, I reached out and took out the portable power bank that had been with me for a long time from the drawer. It has a simple appearance, with a silver shell that emits a faint luster in dim light. I carefully selected it because I believe in the quality assurance of big brands. I habitually pressed the power button, and the indicator light instantly lit up. The soft blue light gave me a hint of comfort. I plugged in the data cable, connected the other end to my phone, and then continued to immerse myself in work, completely unaware of the impending storm.

Time passed by minute by minute, and everything around seemed to be immersed in a peaceful atmosphere. However, just before this tranquility was shattered by the soon to be completed project, suddenly a strange "sizzling" sound came from the corner of the table, a sound that had never been heard before, sharp and piercing, as if some uneasy force was brewing in the air. My heart suddenly tightened, and I instinctively lifted my head, quickly locking my gaze on the charging power bank.

I saw the temperature on its surface rise sharply, and the silver shell began to twist and deform, making a tiny "bang bang" sound, like a time bomb about to explode. I was stunned, my brain seemed to lose its ability to think at that moment, and I could only watch helplessly as everything happened. But my instinct for survival quickly made me react. I stood up abruptly, tightly gripping my phone with both hands, afraid that it would be damaged in this sudden disaster. At the same time, my footsteps involuntarily retreated, far away from the "electric demon" that was about to lose control.

Just when I thought it was too late, a gap suddenly opened at the bottom of the portable power bank, and a burst of white smoke accompanied by a pungent smell gushed out. Then, a deafening explosion shattered the silence of the night. The whole room was instantly illuminated by flames, and I felt like I was in a nightmare. All rationality and calmness collapsed at this moment.

Fortunately, due to my timely withdrawal, I did not suffer any direct harm. But the shock wave of the explosion still made me lose my balance, stumbling a few steps and almost falling. When I stood firm and regained my senses, the scene before me was shocking: books scattered on the bookshelf, items on the table were crooked, and the portable power bank that had once provided me with countless conveniences had now turned into a pile of burnt scrap metal, with its remains scattered around. The air was filled with a pungent smell of burning and smoke.

I stood still, with mixed emotions in my heart. Shocking, fear, and post anxiety... various emotions intertwined, making it difficult for me to calm down for a long time. I never imagined that such an ordinary item in daily life could instantly transform into a life-threatening 'electric demon'.

Afterwards, I carefully checked the purchasing channels and production information of the portable power bank and found that it was indeed produced by a legitimate brand. However, looking back on the process of use, I also realized some possible oversights, such as placing it in a high-temperature environment for a long time or failing to conduct safety testing in a timely manner after multiple charging and discharging cycles. These seemingly insignificant details may be the root cause of this accident.
