It hit 38°C (100°F) in my apartment last week.
I was this close to buying a $500 portable AC — until I found this $29.99 gem from China.
What is it?
The Portable Mini AC Unit is a compact desktop air cooler.
It’s about the size of a large water bottle, but it actually blows genuinely cool air.
Why I love it
- It actually works. Not just a fan — it has a small cooling plate + water tank that drops the air temp by ~5-8°C.
- USB powered. Plugs into my laptop, power bank, or car charger. I bring it to the office.
- Super quiet. ~35dB. I sleep with it on my nightstand.
- Under $30. I was skeptical at this price, but it’s been running daily for 3 weeks.
The catch
- Water tank needs refilling every 6-8 hours (small trade-off).
- Only cools about a 10㎡ / 100 sq ft area — it’s a personal cooler, not a whole-room AC.
- Needs ice packs in the tank for maximum cooling (they include 2 reusable ones).
Verdict
If you’re working from home, studying, or just want a personal cool breeze without installing a window unit — this thing is a steal at $29.99.
I bought two more as gifts. Seriously.
