Mantric Rechargeable Remote Control Knicker Vibrator I got on sale for 50% off. I'm not super into the whole public thing, but I've been using it way more than my magic wand, that fucking tip is shaped perfectly. Plus it would make an excellent phaser prop.
I keep an extremely small 64GB USB-A/USB-C flash drive on my Keychain so I can move files between phones, phone to computer, or load movies and TV shows from a computer or phone and plug into a TV to play.
It's only $10 and sometimes it's very convenient to always have on hand the ability to move files around without the use of a network or the cloud or whatever. The size of it is extremely small.
Verbatim 64GB Store ‘n’ Go Dual OTG USB 3.2 Gen 1 Flash Drive for USB-C Devices – 2 in 1 Type C Thumb Drive https://a.co/d/40uW3fE
I bought a nice pair of fingernail clippers. ~$15 Green Bell from Japan. You hardly have to apply any force to the lever at all, and the nail just slices off neatly and falls inside. Not like my old cheapo pair that went "KACHONK" and endangered anyone in my vicinity of shrapnel injuries.
A pi zero w. Need a wireless Android Auto adapter? Flash the right image. Need a Klipper controller for a 3D printer, flash the right image. Need to add a wireless thumb drive to any device that you can drop files to over the network? Flash the right image and run a few commands. They are very cheap and insanely versatile. I originally got a handful for $5 each and am still finding uses for them.
Breakaway charge cable for my phone! They act like those old MagSafe chargers for Mac, and when I'm clumsy, instead of a busted off charge port, no damage! I also have curious cats who can test gravity without wrecking my phone.
You can get a wax seal kit for that much. I have a whole set now, but I seal absolutely everything. All you need is a candle, a wax melting spoon, a seal, and sealing wax
Don't know if you'll get something for as low as $20, but a small thermal printer. Functions as a label maker on steroids, there is no ink, or proprietary* paper. Some thermal paper rolls have built in stickers, some are transparent, some have special shapes and colors, etc.
I've used it to label plants, tools, cables, boxes, so-so-many gridfinity boxes. It takes 1-2 seconds from hitting print to having it ready.
* not entirely the case, in that some have set sizes, or markings to automatically feed and count. However, these are low tech, and there are third party vendors.
Slider style EDC utility knife. Small, lightweight, and because the blades are cheap and easily replaced you can abuse them - cut on concrete, pry stuff, if it breaks the blade, not a big deal.
My basic bitch wireless phone charger stand. Holds it at a good angle so I can see when someone sending me a Teams message while I'm pretending to work.
Moondrop Chu 2 earphones. I use expensive Hifi gear at home, but those are more than good enough on the go while also being cheap enough for me not to have to worry about them getting damaged or stolen.
Thinkpad T440p docking station, I get everything these days is USB C but I love having a docking station thats sturdy and has tons of ports vs a dongle that hangs off the side of my laptop and has maybe six ports.
Car charger that does the OnePlus specific fast charge thing. Cost me $12 delivered on AliExpress. Adds about 2% per minute to my phone battery. I love it so much.
It also has a second port which does "normal" fast charge for any passengers.
LED adhesive strip lighting for the back of my TV. Back lighting is super soft on the eyes and with color changing you can incorporate the color to match the mood. Playing Zelda, green. Watching sci-fi blue/purple. Halloween content, orange. Etc
Bought a Rovyvon keychain flashlight I believe was around $20 that's amazing. It's Iike 650 lumens or something and it's tiny so I just have it on my keychain and turn it on at night if I need it in a jiffy.
Little remote ring for my phone. I can change the music/volume during my walks without having to dig my phone out of my pocket/etc. I also use it when gaming to change songs without having to put down the controller, same when I'm knitting.
Love is a bit of an overstatement, but I got a cheap Walmart brand USB hub for my laptop since it only has a single USB male (female?) port and I needed more for my mouse and thumb drives. Definitely worth it to ensure I could save work to my thumb drive at college.
I like to do photography and timelapse videos, so my favorite gadget is a collapsible tripod I can use with my phone. It doubles as a selfie stick and includes a carrying bag and an optional bluetooth remote.
