+100w chargers are one of the products I prefer to spend a little more on, so I get something from a company that knows it can be sued if they make a product that burns down your house or fries your phone.
Flashlights? Sure, bring on aliexpress. USB cables with pop-off magnetically attached heads, no problem. But power supplies? Welp, to each their own!
But seriously, it's harder to accidentally make a USB cable that fries your equipment. The more common failure mode is it fails to work, or wears out too fast. Chargers on the other hand, handle a lot of voltage, generate a lot of heat, and output to sensitive equipment. More room to mess up, and more room for mistakes to cause damage.
