“Customer Review: This portable air conditioner is compact, easy to move and very convenient for small spaces such as bedrooms or offices. It cools fast with its three speeds and LED lights give it a modern and welcoming touch. The noise is moderate: silent in low and louder in high, as is normal. The controls are simple and intuitive.”

I knew better than to move it in between rooms this time, so I found a place in my office, and it stayed there. The water spritzer part went out first. However, the fan was still working fine.”

“Customer Review: My bedroom is above our garage with a large south facing window. This means it gets super hot no matter the central AC setting. So, instead of spending a fortune on electric to have my central AC continuously try to ‘catch up’, I added a portable unit to my bedroom. I really didn’t want a window unit, and this was the perfect solution.”

The remote control is easy to use and the temperature controls make sure that you can set it and forget it. It’s really quiet and looks amazing in any room you put in.

Frequently Asked Questions
Q: Do portable air conditioners need to be vented?
A: Most compressor-based portable ACs require a window vent to expel hot air, but windowless evaporative coolers and personal neck fans do not. Check the product type before buying.
Q: Can a portable AC cool an entire house?
A: No—portable units are designed for single rooms. For whole-house cooling, consider central AC or ductless mini-splits.
Q: Are evaporative coolers effective in humid climates?
A: Not really. Evaporative coolers work best in dry heat. In humid areas, choose a compressor-based portable AC with dehumidifying function.
Q: How much electricity does a portable air conditioner use?
A: It depends on the BTU rating. A 10,000 BTU unit uses about 1,000–1,500 watts per hour—similar to a microwave. Look for Energy Star models to save on bills.
Q: Can I leave a portable AC on all night?
A: Yes, most modern units are safe for overnight use, especially those with auto shut-off, timers, and quiet sleep modes. Always follow the manufacturer’s guidelines.
