For me it was a generator. Moved in to a new neighborhood and discovered that the power goes out frequently here. Mostly because all the power lines are above ground and old trees keep falling on them. It was during covid and my kids were remote schooling through zoom. Went and bought a 3500 watt generator to keep the internet and refrigerator and freezers running. Its been the most handy thing I got since we moved in.

This was my thought exactly! I ended up signing up for access on 11 servers in a mix of mastodon, lemmy and kbin. Probably went overboard.
