Can I use the Optima Steamer DMF where there is no electricity?

All Optima Steamer DMF machines are mobile units although it needs to be plugged to an electricity point but consumes as little as 350W. To obtain such a small amount of electricity the machine could be run from a battery with an inverter, but we recommend a portable electric generator that also supplies electricity to a vacuum cleaner. A 2000W electric generator would serve perfectly the two machines. We can also recommend one if necessary.
