I have a number of items, languishing in boxes from hell to breakfast, that I periodically wonder why I ever bought them. One such item is a self-heating coffee mug. In the interest of full disclosure, this is not the first or only example I have of such a thing. This particular example is designed with a “docking base” (that’s what they call it) that sits inside your cupholder. When you drop — excuse me, “dock” — the mug onto the base, it powers up, activating a tiny heating element inside the mug, which theoretically keeps your coffee warm. In reality, it does no such thing, and the cable just gets in the way, and hangs inconveniently out of the cupholder, preventing you from using it for any non-powered coffee cups. Basically, it’s a worthless piece of garbage, but it sure seemed cool when I bought it.
I also, it’s worth pointing out, have another powered cup that it supposed to keep drinks cool. This one does precisely nothing. Seriously, nothing at all. You plug it in, the light comes on, and nothing happens.
What high-tech gadget do you own that has no business being high-tech at all?
