A well made thermos (like my zojirushi) will keep stuff cool for more than one day. And coffee hot from dawn till dusk. No batteries or cables required. I'll never understand these things.

I cut out the middle man with a Zojirushi coffeemaker that brews right into a vacuum-walled carafe. No hotplate to burn the coffee or sizzle the drips when you remove the carafe; brewed coffee stays hot and fresh for hours; can bring the pot to the breakfast table without it going cold.

  Thermal carafes are fantastic, I really don't get why they aren't the default. I got one in college because it seemed like the obvious choice, and it was SO much better than I expected. I'll never buy a glass one again. They're not fragile, the coffee stays just as hot for at least 4 hours if not much longer, and because "effective insulation" means "doesn't exchange much air" it also keeps it from oxidizing as quickly.

  You can buy that Zojirushi and a whole pound of good beans for less than the price of the "winner" in this advertorial.

    Ah yes, I forgot to mention the obvious, the linked article is an infomercial. Glad somebody else pointed it out.

    Please recommend a better article! This was the least-bad one that I could find on the topic, after my unsuccessful search for a blog with tests based on science.

> A well made thermos (like my zojirushi) will keep stuff cool for more than one day. And coffee hot from dawn till dusk. No batteries or cables required. As pointed out in the introduction of the article, this is not the same use-case; there are some types of coffee or tea that require specific infusion temperature and duration, something you can’t do with a normal mug or a thermos. You can however prepare them using a thermometer, you don’t need a "smart" mug.

  The article didn't seem to mention anything even slightly along these lines, and not at all in the intro. The closest it gets is "it tastes best around 135F" - insulated mugs can do that too, they just won't keep it exactly there for hours. If you're using an AI summarizer, maybe check the output more closely?

I pointed out this is a different use-case, and then gave an example based on my own experience. I’m sorry if this was not correctly worded and felt like this was the use-case the article was refering to.

And coffee hot from dawn till dusk. It will also keep your coffee lip-blistering hot for way too long. Keeping things hot with a vacuum flask is a problem solved 100 years ago. But that's the other side of these mugs: they are supposed to bring the temperature down to (and keep it at) the temperature you specify. Double-walled mugs don't do me any good if 30 minutes later the fluid is still at 198F/92C.

  I brew a little strong and then throw in an ice cube.

And you can easily get vacuum insulated mugs that are dishwasher safe, whereas only one of the smart mugs in the article is dishwasher safe. Looks like Zojirushi is not dishwasher safe though.
