Our newest creation!
The Frankencooler Blowbox Twin is a revolutionary, compact design that can be mounted to a full-size cooler or used independently with any soft-sided cooler or lightly modified (drill 2 small holes) hard-sided cooler for hours of relief from blistering temperatures.
Our most complete dual blower package, requiring only a few inexpensive supplies from Home Depot/Lowes to finish (screws, wire & connectors, silicone). Most individuals with a little mechanical aptitude can complete this project in a weekend or less.
NOTE: As many people don’t have 4″ and 4.25″ hole saws, if requested, I can pre-drill these in the case for you.
The Blowbox Twin comes with a 10′ corded 12V power plug, but for cooling anywhere, the included battery box will accommodate any of our ultra-high-quality Bioenno Power lithium iron phosphate power cells for up to 8+ hours cooling off the grid.
Compare the Blowbox Twin to any purpose-built cooler AC on the planet – none can match its temperature differential, air velocity, variable speed, size, and versatility.
