That time a highly rated power bank almost caught fire in my bag

In my experience, a lot of gadget reviews skip over safety checks in favor of talking about specs. I picked up a power bank after reading several positive write-ups that praised its fast charging and big capacity. A week into using it, I had it in my backpack and noticed a weird, warm spot. When I pulled it out, the thing was puffed up and had a sharp, chemical smell. I unplugged it fast and set it outside on concrete, which was pretty scary. This showed me how some reviews might not test gadgets under normal, day-to-day conditions. Your mileage may vary, but I now take any early review with a grain of salt, especially for battery stuff. I've started waiting for more user feedback before buying, which has saved me some trouble.
