French Press Coffee Maker
No heating element, so it is allowed in dorms where a hot plate is not. Borosilicate glass and a stainless frame — rinse the mesh filter and it is ready for the next pot, no paper filters to restock.

The element is enclosed, which is usually what makes it permitted where an open coil is not. Variable temperature is the upgrade worth paying for if you drink tea or make pour-over coffee.
Make it on Sunday, drink it all week. Check the height against a mini-fridge door before buying, because that is where it has to live and most pitchers are an inch too tall.
