Campboy,
We aren't exactly sure what the draw is on a generator. But we do not recommend using a generator for a few reasons. We know that the Apollo draws 17 amps of power when running. There have been reports from customers that their ovens won't work at all on generators, but work fine when connected to land power. We also do know that generators can send "dirty signals" to the control board of the microwave unit and actually cause the control board to not work and/or to blow fuses inside the unit. Now, these instances don't always happen when a generator is used, but since the Apollo units use so much power it is not recommended to use a generator. Hopefully that information helps you out. Just post or give us a call if you have additional questions. Thank you.
