How big is your battery capacity?
No one is saying you can't; just that the typical single "marine" size 24 battery won't hang in there long enough to make several cups of coffee.
A 1500 Watt inverter will draw 125 amps at rated load.
A typical Keurig will draw 800 watts when heating or 67 amps.
Since most Group 24 Marine batteries have about 70AH of battery life (at 5 AMPS draw), at 67 amps a fully charged battery will reduce a 100% battery to inverter cut out voltage (10.5 volts) in about 15 minutes.
Next time you do this watch your micromonitor display and watch what happens to the "voltage idiot lights" as the coffee brews.
Remember also you must recharge your battery when the "Good" light goes out (50% discharged) in order to prevent permanent battery capacity loss.
