Depends what you call tech. I've been looking for a salt nic vape (say 10 watts) in the 1 ohm range with a easily replaceable battery for the last year. Bonus points if it doesn't leak to hell and gone. Haven't had a whole lot of luck with that so far.

Pretty much any portable device with a standard type, user replaceable battery. God bless Ryobi and the other power tool companies for building weird but useful tools beyond power drills. All with replaceable batteries.

At one point I was looking for any type robust portable storage media that had reasonable storage capacity and good shelf life (2+ years), and was large enough to actually write on a label what was on it. So far the closest I've seen since 2005 have been the portable SSDs and the newish USB m.2 enclosures but that's still not quite what I'm looking for. Too large and non-standardized. Gave up on it several years ago and built a publicly accessible Nextcloud server. Yes I'm an old fart, dislike cloud storage and miss the floppy, Zip and Mini-Disk storage formats. I currently have a dozen mystery jump drives sitting on my desk in a 3d printed rack with only the vaguest clue whats on any of them. Most of them so small you can't even put a key tag on them. I hate it.

A reliable multi port (4 or more) USB-C charger that can output 65+ watts on all of its ports at the same time.

A reliable source for 100w USB-c 3.x PD cables that don't cost an arm and a leg. Anker makes good PD cables but tops out at USB 2.whatever.

Pretty sure more would come to mind if I sat and though about it for a while, but I've got to head to work now.
