The maximum watt draw is 360 watts, but because of the way the Duct Blaster fan and controller use power it is best to double the watt draw with sizing a power source.   So a 720 watts will work best.

Portable Power Inverter Options

We occasionally get asked about portable power supplies because a new home might not have power yet and you need to do a duct leakage test or you are using the Flow Blaster attachment for the Duct Blaster fan and you don’t want to drag an extension cord around from register to register.  A power inverter is a device that you plug in to charge up ahead of time and then carry into the field to supply power.
