Why Won't My 1000W Inverter Run my 800W Coffee Maker?

Could be that you have a phantom draw (maybe your fridge?), could be that your coffee maker is higher wattage than you have been led to believe (especially during startup), but it also could be this thing I used to hear but now can find no evidence for: That some inverters and inverter generators really don't like appliances that generate heat in the same way a toaster or electric heater does. Something about the inverter seeing it as a short? Don't quote me on it.
