Micro Air
Hi, just looking for input from people that have them on their effectiveness. I am thinking of getting a portable genny for the 5th wheel for those times that I need an AC and don't have power. I ha...

Here is the short electrical engineering of what is happening.
All electric motors that power heavy loads have a "starting capacitor" (there is a mechanical switch that cuts out the capacitor once the motor is "up to speed").
When a capacitor is fully discharged (before the motor starts), it "looks like" a short circuit when power is first applied. Additional/larger starting capacitors just make this worse. The MicroAir actually "limits" (slows down by a few hundred microseconds) how fast that capacitor charges up eliminating the current spike.
