The Frankencooler Blowbox is a revolutionary, compact design that can be used with any soft-sided cooler or pair with any lightly modified (drill 2 small holes) hard-sided cooler for hours of relief from blistering temperatures.
Our most complete package, requiring only a few inexpensive supplies from Home Depot/Lowes to finish (screws, wire & connectors, silicone).
NOTE: As many people don’t have 4″ and 4.25″ hole saws, I am pre-drilling these holes in every case.
Blowbox comes with a 10′ corded 12V power plug, but will internally accommodate any of our Bioenno power cells for hours of off-the-grid cooling.
Compare the Blowbox to any $600 purpose-built cooler AC on the planet – they can’t match its temperature differential, air velocity, variable speed, size, and versatility.
