able to help with that possible problem. In this Instructable, I repurposed a Peltier cooling system used in a portable drink cooler. Let's go check it out...
Step 1: Parts
Power source, 12vdc
Assorted Misc. other things
Step 2: Step 1
Step 3: Step 2
Step 4: Step 4
I installed a power lead tail for easy connect because the power source is my test bench power.
Step 5: Step 5
The feet installed to elevate device for air flow came from my Dremmel tool. They are polishing pads that I have never used.
Cell-2-Cool is ready for business
The plate gets really cold. Some sweanting does occur but not where the phone contacts the plate.
I have noticed the phone holds a longer charge. Did not expect that.
