Considering I bought a 300 watt flex panel for $65 (supposedly over 20%EFF)
Who cares?
The benefit
of the 12 volt surviving
Of Possible cooling fan operation
And added free range is worthwhile
And In the winter you could likely use excess power to power the seat heater
Seems like a no brainer as a gimmick and convience option
It’s all about cost, as manufacturers offer it you will drive cost down and reliability up.
I think of all the new car option costs and have to say no one seems to care about buying the $2000 premium audio I don’t see why this is any more efficient
