Hi,
While inverters are around about 90% efficient, a group 29 battery only stores about 1200 watt-hours. Of that, only 50% should be used, if long life is expected. If the coffee maker draws 300 watts (mine does) and runs for 10 minutes, then around 60 watt-hours (or 10% of usable capacity) may be consumed.

go without a drip coffee maker avoiding the use of an inverter. I think inverters are not very efficient because usually you have a larger battery bank.
