I would be skeptical about the longevity of those products and whether they are safe to use or not. You certainly don't want your car to catch fire due to a poorly made product. -Caveat Emptor-
Certainly doing what you know works is a good bet. "switching" power supplies and "buck-boost" converters are much more efficient than a dropping resistor of some kind, and really don't generate hots of heat. They are used in all kinds of electronics.
