✅ Multi-Function Features
Many models double as humidifiers, air purifiers, or smart devices, offering more than just cooling — they enhance your entire indoor environment.
Not every cooling device delivers on its claims. Here are key issues to avoid:
✘ Overhyped Fans Disguised as ACs
Some products are just glorified desk fans. Real portable ACs use evaporative cooling or compressor technology for noticeable temperature drops.
✘ Poor Battery Life or Very Limited Runtime
If going cordless, make sure the unit lasts more than a couple of hours — especially in hotter climates.
✘ Limited Cooling Area
Some budget models are only effective within a few feet. Look for specs that match your room size or usage needs.
✘ Loud Operation
The hum of an AC is expected — but cheap motors can be distractingly loud. Choose models with verified low-decibel performance.
✘ No Refund or Warranty
Reliable brands back their products. Be wary of no-return policies or vague customer service options.
