I’d been eyeing the Mamolys “Cooling Ace”, one of those cola‑can-sized portable “AC” units, after being bombarded with ads claiming ice‑cold blasts in seconds. The promise of purifying, misting, rechargeable cooling at a low cost was tempting. So, I took the plunge and tested it for myself.
What Is the Mamolys Cooling Ace?
They market it as a bladeless, USB‑rechargeable “portable air conditioner.” With a compact tower design, 800 ml tank, three fan‑speeds, LED lighting, and whisper‑quiet operation, it’s pitched as a mini cooler, humidifier, and purifier in one.
Why I Tried It
My home office gets stifling in the afternoons, but installing a full AC isn’t an option. I hoped the Cooling Ace would give me just enough of a cooling edge at my desk without blowing up my electricity bill, especially since it cost under $70.
My Experience Using It
Unboxed, it looked sleek and felt light. Filling the tank and plugging it into USB-C, I tried the low setting first, and it was nearly silent and gave a faint, wet‑cool breeze. On high, airflow increased, but so did the noise, and the mist effect didn’t last long.
That initial cool rush faded after about 10–15 minutes; after that, it only felt like a damp fan. In my medium-sized room (120 sq ft), it couldn’t lower the air temperature, though it did feel marginally fresher near my face. The water lasted about 4 hours before it smelled stale, and I had to clean the filter frequently to avoid mildew.
I gradually realized it’s not a traditional AC as it never felt like one. Once I accepted it as just a misty personal fan, it was fine. But the marketing tone? Way overblown.
Pros
- Compact, lightweight design with USB‑C charging
- Quiet on low, portable enough for desk use
- Short bursts of misty airflow feel fresh on the face
- LED nightlight adds ambient value
Cons
- Doesn’t actually cool air
- Limited runtime (4–6 hrs) between refills
- Filter heats and smells musty if not cleaned
- Marketing misleads with “AC” claims and purification buzz
Is It a Scam?
It’s not a scam in the sense that it works as it says, but the product is heavily oversold. The brand hides behind flashy marketing, fake urgency tokens, and unverifiable origins. What they do deliver is a humidifying fan, not a cooler, purifier, or “advanced German tech.”
Does It Really Work?
Sort of, yes, for mild, face-level mist and slight comfort. No, for actual cooling, room temperature reduction, or air purification. It’s enough to feel pleasant during a hot Zoom call, but not enough to keep a room bearable in a heatwave.
Alternatives
- Evapolar evaCHILL
- Arctic Air Pure Chill
- Hessaire MC18V
Conclusion: Would I Recommend It?
Only if you want a light, misting breeze at your desk and don’t expect real cooling. The Mamolys Cooling Ace is more decorative than functional as a fun gadget, but not a replacement for actual AC. For under $70, it’s worth a shot for personal, short‑term use, but don’t buy it hoping for a cold room.
