The Johnny Hat uses a solar panel to produce electricity to power the ventilation fan inside the fixture. It automatically turns on when the Sun rises, and shuts off when the sun sets. It has been strategically designed to fit on the existing ventilation system without any modification! By design it draws fresh air in through the vents at the top of the structure, down through the holding tank and out the stack. Everyone that uses the Johnny Hat has told us "you can't smell anything" and "it is noticeably cooler"!

We wouldn't sell it if it didn't! The residential recommendation for a bathroom fan is roughly 1CFM per square foot; we have doubled that for the standard sized portable restroom! We also designed the entire product around the power source; the solar panel. Because we did this, our solar panel captures much more power so it will even function in circumstances where sunlight isn't optimal for other solar products!
