What is your recommendation for a dock that comes with a power supply?

This is a cool idea if you really needed some cooling for a Raspberry Pi-like device that has extremely stringent space requirements, but I can’t imagine buying anything bigger than a tablet that doesn’t have a fan.

That being said, I have a Microsoft Surface Pro and it would be nice to have even a little bit of active cooling.

I bought a sewing machine and am starting to learn how to do some basic things. I will likely try to make one for the 16 when I get mine next year. If you can’t find anything, I could make one for you at cost of final materials (I won’t include consumption from mistakes) and shipping. The practice is good enough for me.
