I think it helps, but I haven’t had a long enough drive yet to know for sure.

Well, I finally took a trip long enough to test it and it works. On the almost two hour ride up with the sun shining and the top down I had the fan on and the iphone was running Waze and stayed reasonably cool. About the same temp as my wife’s iphone that wasn’t on a charger sitting in her pocket. On the way back the weather was cooler and the top was up and the fan was off and the phone was significantly hotter. I’ve got a 3.5hr drive tomorrow and I’ll check it again and report back. If it’s good then I’ll figure out the best way to make more.

That's awesome. Great ingenuity.

I need to gauge interest before going too much further down the road on this project. Here is where I am as of now:
1) I can 3D print units and the finish will be good, but not perfectly smooth as you would expect from a commercial grade injection molded part. Take a look at the photos in this thread for examples.
2) The fan is not silent and you can hear it with the top up and the radio off when you are sitting with the engine off. The engine sound and/or radio appear to be enough to cover the noise and I can’t hear it if I have the top down. I could slow the fan down to make the fan quieter, but on the positive side, this helps to remind you to turn it off when you park the car. I don’t know if the USB port will shut off on it’s own when the car goes into sleep mode. I haven’t tested it.
3) Since it doesn’t turn off on it’s own, if the USB port does not go to sleep when the car does, if you leave it on it could drain the car battery. This would be no different than leaving any USB device plugged into the car.
4) It has an on/off switch vs. a temperature sensor. I was going to design in a temp sensor, but I thought simpler was better as there is less to fail over time.

Send me a private message if you would be interested in purchasing one, and if you really want to help, let me know what you think would be a reasonable price and I can figure out what to do next.

I appreciate the encouragement, but given the current demand the financial math doesn’t work.

Got to use it today! Thanks Kwajtrader. Looks great. Tested it with Waze and streaming music and it kept it nice and cool. Can’t wait to test it while stuck in traffic for an hour.

Used mine today on a 3 hour road trip and the phone charged and stayed cool. Great job Kwajtrader.

Glad to hear it guys. Everyone has reported back that it solves the problem. I have used it on 3+ hour drives with WAZE and podcast streaming with no overheating. Now I just have to convince my wife that I can actually solve problems…

Might be worth setting an Esty store or something along those lines.

To date the volume has been too low to make it worth the hassle.
