Here's a cooler that anyone can build. It's my design and it fits right into your waistband. I used a 5v-24v step-up converter, a miniature switch from an old Game Boy project, and a micro USB breakout board to make this happen. This cooler relies on a power bank for its power source, which helps reduce the weight of the unit itself and works really well. Feel free to modify it and share your own versions with me - I'd love to see them! Thanks and enjoy. P.S., my file might be a bit rough around the edges, but I'm in a hurry to get this done. Please don't focus on criticizing the model; instead, improve it and share your improvements with others.
