Let’s admit it, we’ve all bought something completely unnecessary… and loved every second of it. That’s the magic of cool useless tech gadgets. They’re the weird, unnecessary, and sometimes ridiculous devices that make us smile, laugh, and maybe even go “Whoa, that’s kinda genius.”
Whether you’re shopping for yourself, looking for a gift, or just browsing through the rabbit hole of Amazon’s strangest listings, this list is for you. Here are 15 essentially useless but kinda cool tech gadgets you’ll probably buy anyway.
1. USB Pet Rock – The OG of Useless Tech
You plug it in. It does nothing. Nothing. But it’s hilarious, nostalgic, and a conversation starter. The USB Pet Rock is the king of useless tech gadgets and somehow, still cool.

2. Desktop Vacuum Cleaner – Pointless or Genius?
It’s a tiny vacuum for your desk. You’ll question why you bought it, but then find yourself using it more than expected. Crumbs and dust? Handled.

3. LED Color-Changing Shower Head
This gadget lights up your water stream with rainbow colors based on temperature. No batteries required—just water pressure. It’s flashy, fun, and very extra.

4. Magnetic Levitating Bluetooth Speaker
This Bluetooth speaker hovers mid-air using magnets. Do you need it? No. Is it insanely cool? Absolutely.

5. Smart Plant Pot That Talks to You
Yes, this is real. A smart plant pot with sensors that tells you when to water it—and may even sing. Useless? Maybe. Adorable? 100%.

6. Bluetooth Beanie Hat – Warmth Meets Music
Why wear headphones and a hat when you can wear both in one? This Bluetooth Beanie streams music directly from your phone. Useless? Maybe. Stylish? Yes.

7. Rechargeable Hand Warmer
A heated pebble-shaped device that keeps your hands warm and charges your phone? Sounds silly… until winter hits. You’ll thank yourself later.

8. Self-Stirring Mug – Why Lift a Spoon?
Too lazy to stir your coffee? This mug does it for you. Unnecessary. Also, weirdly satisfying.

9. Mini Air Conditioner (USB-Powered)
It barely cools anything, but the cool mist and LED lights make it perfect for small desk setups. Another cool, yet useless, tech gadget you’ll pretend was a smart buy.

10. Couch Console – Ridiculously Specific, But Genius
It holds your drink, phone, snacks, remote, and even has a balancing cup holder. This over-engineered piece of technology is the epitome of “useless but awesome.”

11. Touch Sensor Night Light for Walls
Stick them on your walls. Tap to turn on. You could use a switch, but where’s the fun in that?

12. Laser Projection Keyboard
This one screams “sci-fi prop.” Project a keyboard onto any surface and type away. It’s clunky and glitchy, but boy, is it cool to show off.

13. Smart Mirror with Time and Weather Display
Looks like a regular mirror until it lights up with the time, date, and weather. No one needs this, but you know you want one.

14. Car Heads-Up Display for Your Smartphone
Project GPS and speed onto your windshield like a fighter jet. Feels high-tech, looks awesome, and is surprisingly affordable.

15. Bedside Shelf with Built-in LED & USB Charger
This attaches to your bed frame, holds your phone, lights up your book, and charges your gadgets. Yes, you’ll feel like a tech lord in bed.

Why Do We Love Useless Tech?
There’s something oddly satisfying about buying something you don’t need. It’s about fun, novelty, and the little joys of life.
These cool useless tech gadgets are:
- Conversation starters
- Great for gifting
- Excellent for affiliate sales
- Scrollable, shareable, and sometimes even… slightly useful!
You may not need a USB-powered mini humidifier that glows, but does it spark joy? That’s what counts.
These gadgets are NotSoEssential, and that’s exactly why they’re fun.
