A 5 cup DC 12 V coffee maker requires 240 watts of power.
This could easily run that.

The concept behind it is you run it longer than a Genset
and it is quite enough that it is not annoying.

Look at it like its a battery charger and a heater.
From the perspective it works better than a genset.
And you don't need as big a battery bank.

Yes, I checked it out at Newport last week. Very slick. But the Bang for
the Buck is a bit lacking - its $12K and doesn't put out enough to run a
coffeemaker. On the other hand, its a neat trickle charger, and would be a
good match for a lightweight boat that uses outboards instead of diesels
(like a catamaran).
