Can I get help with battery math...batteries-inverter-coffee

Please don't run a generator in the morning, your neighbors will thank you for it. You can get much lower watt single cup coffee makers. I like to get up before dawn and fish from the kayak from a few hours before everyone gets up, so I found a 300 watt single cup unit that works just fine off our inverter.

There is this little guy from keurig that is only 700 watts as well. Lots of options for sure.
