I bought a Nespresso machine for the same reason a couple of months ago. Headed off on a trip keen to show off my new toy. Bottom line is it wouldn't work properly. I contacted Nespresso and they said that they won't work on an inverter, he couldn't explain why, just doesn't like inverters. I still use it when I'll have another power source but no luck on the inverter. I'm happy to be proven wrong (I guess it had to happen one day
).
Just thought I'd mention before you head off and get let down. If someone has managed to get one working, feel free to comment.
Well Nespresso is wrong. I live with solar power so everything runs off my inverter, including my Nespresso machine. Only reason I can think of is possibly your inverter isn't a sine wave or it won't pump out enough power.
I have a 250 watt inverter for camping & that wouldn't even think about running the coffee machine. For coffee on the road, round the campsite you can't beat the ROK coffee "machines".
Edit-: just saw a couple of your other posts, do you take a 2500 watt inverter camping? My household one is only 2000 watts & runs everything at home, only thing it won't run is anything to do with heating / cooking, just too much power thrown away. Check out the ROK machines, makes a hell of a great coffee!
