Check out the inverter type ones such as this one [1] It isn't light but it is quiet and adjusts the amount of power it uses depending on cooling needs much better than a typical window unit making it more efficient.
The Midea U window AC units are a really good product. I am easily cooling a roughy 1,200 square feet space with only one of the 12k BTU units and a few ceiling fans, and it typically gets into the 90’s F here in the summer with significant humidity.

I agree. The U shape is a gimmick, but a good one. It helps it be quieter inside, but even outside they are quite quiet. I have whole house AC, but I like the windows open, I like being hot. Just not when I’m sleeping. Basically only downside is a truly terrible app that is the only way to access just a few features.
Terrible doesn't begin to describe that app. Honestly what does the turbo button in the app even do?
I have one in a room on the far end of the house that the main AC can't reach, it helps reduce power usage since I can keep the rest of the house warmer.
