However, a regular Keurig (not a one cup) will work fine on the Magnum1212 modified sine wave inverter. We have been doing this for a couple of years now. The Magnum1212 also has short term specs that exceed the continuous rating. Note that we switched to Battleborn Lithiums this year, because using a Keurig continuously wears out lead-acid batteries much quicker. Lithium batteries are not affected by running them down to 30%.For this record this solution ONLY works for those with the 1000W Magnum pure sine wave inverter. The Nespresso machines do not work with modified sine wave (MSW) inverters. I have the Magnum MM1212 1200W inverter and discovered that a Nespresso machine will not work at all on my inverter power the hard way. I did some research after getting back home from that first trip trying this and found out Nespresso acknowledges this is not a workable combination.
What I noticed is that, according to my battery monitor, the peak draw from the Keurig is about 126 amps DC and that is for 30 to 45 seconds. It only heats what is needed to make a single cup of coffee. Once the first cup is made, it heats and stores heated water for the 2nd cup, but water in the side reservoir is not heated. If I know that the last cup has been made, I just hit the power off button to avoid heating the water for the next cup.
