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. This cooler does everything the original Frankencooler does, only much better – Much faster, easier assembly, 95% complete, total separation of incoming air from ice/water, more ice capacity – no insulated divider or radiators taking space, small head unit can be used remotely if needed, the coldest temperature differentials.

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 average mechanical aptitude can complete this project in a day.

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 12′ corded 12V power plug, but for cooling anywhere, the included battery box will accommodate any of our ultra-high-quality lithium iron phosphate power cells for up to 10+ 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.
