Car chargers for usbs, or digital thermometers, or disposable pregnancy tests - it's absurd the amount of compute that ends up even in single use or trivial products.
A lot of that is because those devices have far more than they actually need because the processors/packages are so cheap. Particularly if it's a relatively low volume item it's probably cheaper to just use a slightly overpowered component even if it's a penny or two more vs changing things.
Never mind the car charger, what about the cable itself?
