What do you mean? Tons of IoT devices are powered from mains, not batteries.
- xchip 3y agoTons on IOT devices? Could you mention a few (that are actually useful)? The only one I know is the cellphone. And even if they were powered from mains I don't want it to be inefficient. If they don't come with a buck converter with low quiescent current please don't buy it.
