Yeah, I’ve seen the whole fuss around 100‑W fast‑charge. Regulators basically set a max current and voltage curve, plus thermal limits, and OEMs have to prove their charger stays within that envelope for the life of the battery. If it blows up or the voltage spikes, the manufacturer can be hit with recalls, fines, and consumer lawsuits for damage or injury. They’re forced to do rigorous testing and include protection circuits, or else they’re liable for the heat‑related failures. It’s a high‑stakes game, and I hate when someone skips a calibration step.
