The battery powered wireless remote-controlled AIR single blower cooler is complete.
The power cell is a super high quality 4.5Ah lithium iron phosphate (LiFeP04) unit with onboard cell equalization. The wireless remote has a range of approximately 20′. This cooler is only around a pound heavier than the corded power plug model. While the pump operates at full voltage, the blower is running at 9 volts – a good compromise between airflow and noise.
In testing today (106 degrees) the battery-powered model ran for just under 2.25 hours while maintaining a near 40+ degree temperature differential throughout. At the end of the test, there was still some ice left – a testament to the Frankencooler design 🙂
Upgraded major component packages for both wired and remote versions of this cooler are now available on this site.
