So i was looking at the exact same model of the coffee maker in 110v requires 1750 watt (about 15 amp) and if purchased as a 220v model it requires only 1250 watt (less than 6amps).

I can also get either 110v or a 220v inverter. Wire gauge and length of the run is very short (3-4 feet from the house battery). 1500WATT inverter is less expensive than 2000WATT inverter and the coffee machine costs about the same in either voltage.


Can anyone chime in if there is any benefit to going with a 220v inverter and a 220v coffee maker?

Thanks

Like others have said, stick to the 110v system if you're in the states - so much easier to find appliances for it. Should you find yourself in 220v areas you can always add and step down transformer for shore power (you might need two separate shore power plugs) These are pretty cheap

I wouldn't worry about the wattage. Coffee makers actually don't use that much juice. My 110 coffee maker uses about 8 ah to make 10 cups. Once the coffee is made it uses lille juice, or 0 if you get a maker with a thermos carafe.


The load is high, around a 70 amp draw while making coffee so just need to make sure you have a decent sized bank. I have 6 GC batteries for 600+AH and no problem. Also 960 watts of solar. Since I only make coffee in the morning there is plenty of time to recharge the batteries.


Bottom line is I would vote for 110 v, assuming you cruising in North or Central America or the Caribbean.


Other problem with 220/240 is that US is completely different than most of the world. 4 wire vs 3 wire system and I have no idea if it's easy or hard to crossover.
