This unit is nice and compact. It's certainly quieter than a less expensive non-inverter AC but It's not a quite as it's marketing suggests. Whisper quite is an exaggeration. The Low fan speed setting is too high which results in loud operation. The quiet mode is really the only mode I use because the other three are too noisy. The unit also clicks a lot like the sound of a relay going off, and you get some water splashing noises which is normal from this type of AC but it is really noticeable on this unit. I hope future firmware updates can lower the fan speeds.

I ONLY bought this item because of the other review.I searched for HOURS online, there is absolutely NOTHING out there about this particular AC unit... I called Hisense, I scoured the internet all night into the morning because the model number isn't real. I purchased this unit to satisfy my curiosity and if it turns out to be a good unit I'll keep it. I want to really see who makes this and what model number it is... Hisense had no idea what this product number was.I will update this review after I receive it and test it out. I really hope the other review is accurate because it's one of the best reviews I've read on Amazon

This is exactly what I've been waiting for to install in my Sunlite 16' 13BD travel trailer with its DIY-added 700 Watts of flat-mounted roof-top solar, 600AH of Lithium battery storage and 2,000 Watt inverter.The trailer came with a cheap 5,000 BTU air conditioner which was both insufficient on hot sunny days and used too much power to be run continuously off my solar/battery setup. The old unit consumed ~425 Watts on High Cool, ~60 Watts when the compressor cycled off (rarely), and had a very high measured inrush startup current spike of ~12.9 Amps, which meant I couldn't even run it off my earlier pre-solar 1000W camping generator.This new 6,000 BTU unit is exactly the same physical size as the old unit it replaced but has 20% more cooling capacity and uses much less power with no measurable inrush startup current spike. For example, with my trailer sitting in the spring afternoon sun with an interior temperature reaching 87 degrees, turning on the new AC unit results in a ramping up of fan and compressor speeds to a maximum measured power consumption of ~370 Watts. It remained at this level until the trailer reached my set temperature of ~72 degrees. The power consumption then begins stepping down, first to ~250 Watts with continued cooling, then to ~215 Watts, then it drops to ~170 Watts. It remained at this level while maintaining a cool interior temperature under a continuous spring sun load on the door-side of the trailer. After a period of time, the compressor ramps down and off and power consumption for high-fan-only remains at ~50 Watts (or ~35 Watts on low fan) until cooling is needed again. And if in ECO mode, the fan ramps down and off after ~4 minutes and then consumes under 4 Watts in standby mode. I can imagine that peak power consumption will be higher on hotter summer days, but what I am seeing so far is incredibly impressive!This is the first window AC that I can actually sleep with it in ECO mode because instead of the fan/compressor loudly and abruptly clicking off/on and waking me, it gradually ramps down and then back up!I do wish the remote was RF or Bluetooth based instead of line-of-sight IR based, and I do wish the remote's LCD screen used more English words/abbreviations instead of cryptic symbols, but hey, it's at least a usable remote control, something I did not have before.Note that the power sweep vane is vertical only and can be stopped at any vertical position or allowed to sweep up and down under very low power (I like this new AC unit a lot so far. It's quiet, efficient, and well-featured, but only time will tell how long it survives repeated trips over Utah roads mounted in my travel trailer, versus the much more sedate life it was designed to experience in a residential bedroom window.EDIT 5/12/25: I took a weekend trip to the west desert and encountered much higher outdoor temperatures in the upper 80s with high winds, as compared to my earlier tests at home, and for the first time, I measured power consumption ramp up to approximately 520 Watts upon startup. It stayed at this level for a period of time and when I returned to the trailer later, I found that the temperature had reached 72 degrees and power consumption was now at ~320 Watts, and after a period of time I noticed it was at ~250 Watts (about an hour after startup).This model WCT06W25A is listed as EnergyStar certified (ID# 3706663) on their .gov website.
