Let's go with the following numbers:
1200 watt coffee maker
Brew cycle takes 15 minutes
Two 12 volt batteries at 100 amp hours each
And we don't want to push the batteries below 50%
So each brew cycle would draw 25 amp hours from your batteries
(1200 watts divided by 12 volts is 100 amps; divided by 4 (1/4 hour)= 25 amp hours)
Conceivably you could get 4 brew cycles out of your batteries, assuming the following things:
-
nothing else is drawing power. Not even a clock or single light.
- There is zero loss when using the inverter. (which is not true, there is always loss.)
- The last big assumption is that your batteries could provide that amount of continuous power for that long. I know I ran into issues providing power for a 200 watt Xbox from battery power in my SUV, the power level kept dropping.
I think that if you have to have electric appliances running, the generator is the way to go. Personally as mentioned I've gone away from needing AC power for anything; to the point that on my last dry camping trip a buddy gave me his generator in case I wanted it, and I left it behind.
You
might be able to get it to work with a lower power coffee maker, or rigging something to run from your vehicle and have the engine running while making coffee. However like Bob said, having a vehicle running to make coffee would just kill the aroma factor.
