One of the coolest gifts I’ve ever acquired was a portable cooling system, then when I went away for university, our dad got me this portable AC; It was a heavy duty portable AC plus was able to be used virtually somewhere.
I used it in our dorm for the first year I was away for school plus then I even used it in our automobile for a phase of time when the AC in our automobile went out, but the best area about the portable AC was that it was operated by adding freezing water to the device.
When I used it in our dorm room, I always had ice available. When I used it in our car, I kept a cool full of freezing water in the back. When I got into our automobile after class on those tepid summer time afternoons, I would grab 2 bottles of ice water from the cooler. It was the best area of our day, and sometimes, I would even take the portable AC camping plus on trips. The noise was less that what a window unit cooling system would make, but less a little more than a normal sound maker. I enjoyed the little portable AC. It finally stopped toiling about 5 years after it was gifted to me. I recently found them online for a genuinely fantastic deal plus obtained a single for me plus our friend, but both of us take them to the beach, camping, plus even use them in the office sometimes!
