Introduction to Inverter Technology

As pioneers in the air comfort industry, Whynter is proud to introduce the next generation of inverter technology for portable ACs. The variable-speed system allows the compressor to optimize efficiency and power consumption together while maintaining a specified output.

Here are a few of the advantages of our inverter technology:

  • Estimated 40% – 50% in energy savings
  • 2 times quicker to achieve the desired temperature
  • Quieter operation
  • Minimized temperature fluctuations
  • No voltage peaks from the compressor

Hose-in-hose Setup

The innovative two-hose-in-one design and sealed bottom structure of our 14,000 BTU portable air conditioner ensure that there is no heat leakage. This cooling setup extracts and exhausts air from the outside, so the indoor space reaches an independent and balanced cool air circulation. As a result, the NEX air conditioner can cool down the entire room quickly and effectively.

Ultra-quiet Operation

The noise level of this unit is as low as 42dB(A) at low fan speed, making its noise almost as quiet as a library.

Smart Control (WiFi-enabled & Voice-connected)

You can control your portable air conditioner from anywhere with the NetHome Plus app for Android and iOS. This way, you can set the heat or dehumidifier on your system to make your home comfortable even before you arrive. Also, you can use Amazon Alexa or Google Home voice assistant to operate the air conditioner.

Full Coverage Airflow

The fully automatic 80-degree vent louver optimizes the air distribution in the room with a 52% better coverage.

Hassle-free operation

The patented self-evaporative technology in our 14,000 BTU portable air conditioner frees you from needing to drain your unit while it is heating or cooling in most environments. Alternatively, the included gravity drain hose can be utilized for continuous drainage in humid climates. The display includes a handy filter and tank full notifications to take the guesswork out of maintaining your unit.


Move your 14,000 BTU portable air conditioner anywhere for the perfect heat or airflow with the 4-wheel design and handles. It is also easy to set up in most vertical or horizontal windows with the convenient snap-together window kit (included).
