Why We Love It

[Peak Efficiency with Full DC Inverter Tech] This 10,500 BTU SACC(14000 BTU ASHRAE 128) portable air conditioner, suitable for cooling room up to 500 Sq.Ft., boasts a 13.6 CEER rating verified by DOE, representing the pinnacle of energy efficiency in its market. Since we dont inflate the BTU rating of our unit, its size may be larger compared to some other "mini" models that falsely advertise 14,000 BTU. Unit dimensions: 15.5" D × 17.7" W × 29.3" H please make sure your space can accommodate this true full-size 14,000 BTU unit (not a "mini" model with inflated specs)
[Dual-Hose Cooling] Unlike single-hose portable AC units for room that can cause negative pressure and hot air influx, our dual-hose system ensures rapid cooling and maintains balanced indoor pressure for faster, more efficient room temperature control (61°F - 90°F)
[Say Goodbye to Compressor Noise] Inverter Mode reduces the compressor's frequency to 50% load within 2 mins, lowering noise to about 45dB. This allows our Inverter AC to actively adjust compressor frequency for noise control, alongside traditional fan speed settings. You'll no longer have to endure the noise from compressor while you sleep
[Your room doesnt need the same cooling power all the time] During the day, when it's hotter, stronger cooling is needed, which consumes more energy. But at night, cooler temperatures mean less power is required. Inverter ACs adjust cooling power based on the room's needs: use Turbo mode for fast cooling during the day, and Inverter mode at night to save energy. Fixed-speed ACs run at full power all the time, wasting electricity, especially at night
[Night-Friendly Controls] Backlit remote for easy nighttime use, plus a Display Off feature that turns off the top panel lights for undisturbed sleep

Both the intake and exhaust hoses are 5.9" in diameter and 59" in length. If your window is higher and the hoses cant reach, we do not recommend using extension hoses, as they increase resistance to heat dissipation and may reduce the units cooling performance. A better solution is to place the AC unit on a small table or sturdy stand to raise its height
The package includes two 20-inch window brackets and one 10-inch window bracket. If your window is larger, dont worry. After receiving your portable AC, you can request additional window brackets for
In most cases, portable ACs do not require manual drainage. But if the humidity is over 85% RH and the room isnt sealed, moisture from outside can continuously enter, which may exceed the units auto-evaporation capacity and require manual drainage. In such cases, unlike many portable ACs with drainage outlets at the bottom, our unit includes an additional drainage outlet positioned higher on the back, making the process much easier
