I love this unit. I did get an error code 12 when it arrived, but that seems to have been a blip and it's been working flawlessly.Here's my situation:I have a 13 m2 bedroom in the attic with a typical PVC casement window (they're a terrible fit for portable units as they open outward from a hinge). I can't get a split system as I do not have permission, but I also need to sleep comfortably during hot times. However, the UK market for effective AC units is dire. For example, having a dual-hose AC instead of a single hose one (which is what most of the UK market has) can boost efficiency massively by up to 40% with the same energy usage because it doesn't suck the air from the room that's being cooled out the window. The UK market desperately lacks these as the demand isn't there for it.When I saw this unit, I almost dismissed it because I thought it can't possibly be dual hose while being that small. But it is! Even better, you can even put this unit OUTSIDE, and run two hoses that circulate conditioned air to the unit through a window for even more efficiency and quiet. While I can't do that, it's a nice option if I want to carry it downstairs.Not only is it small, but it's quiet, well built, and efficient. I have yet to break 500w on max mode, but I can easily let this thing idle at 300w to maintain a comfortable and dry room temperature. Sleep mode uses even less, around 230w. This is a massive drop in energy consumption vs the typical cheap units that consume over a 1 kw and are relatively loud.I was not only surprised to see an efficient, dual hose, easy to carry unit being sold in the UK, but I was also surprised to receive one and it live up to my expectations! This is great, as being in the UK means most of the year is cool enough to not need this unit so I can put it somewhere out of the way super easily while not in use or carry it up and down the stairs without breaking a sweat.Here's some questions I had before I bought one that I know the answer to now:Q: How does it fare for a light sleeper?A: I'm a somewhat light sleeper. While it's definitely noticeable at night, it's tolerable on sleep mode. It's got a lower hum in addition to the white noise of the fan, and doesn't make many abrupt stop-and-start noises that can be really disruptive but you definitely hear it kick in, but it does do a decent job of ramping it up slowly. It can be disruptive to light sleepers, but for moderate to heavy sleepers this unit is no problem.Q: Is it easy to carry?A: The top of the unit where the vents are work as carry handles. If you're able bodied, you should be able to carry it with ease. Just make sure to not tip it or swing it around as you carry, or you may need to let the compressor rest upright for a while before turning it back on to prevent damaging it.Q: How well does the de-humidification work?A: I haven't yet used the dedicated dehumidifier mode but it really does dry the air. As of writing, the air outside had a relative humidity of 70% at 21C last night, which feels a couple of degrees hotter and is stickier. This unit dried the air in my room to 45% humidity which is perfect, and feels really comfortable. So, even if it's plausible to say the outdoor temperature is fine, UK weather is actually pretty humid most times! The built-in tank fills up very quickly within a couple of hours under these conditions, so I have the supplied drainage tube flow into a 1 gallon container (which must be positioned under the unit, and the end of the tube must not touch the bottom of the container). As I have this unit on a table, it's easy. And to empty it is as easy as tipping the contents of the container in the sink.Q: Can I work from home with this unit on?A: Most definitely! It's quiet enough to work from home with this unit on the background I think. I recommend running it in eco mode with a low fan setting, it's a great balance of power and noise. And, with noise suppression on with Teams or Slack, no one will hear it on the other end (which you probably have on without realizing anyway).Q: How long are the hoses?A: I haven't measured and it's hard to say as they can almost be pulled to any length, but if you plan to route them through the small corner window (as typical of PVC casement windows) you will need to prop it up on a table or something at least 1m tall. I had to get inventive with my unit.Q: How long is the power cable?A: It's actually pretty short at 1.5m. So I would recommend an extension cord be purchased with this unit if your nearest outlet it far away. I don't know how this will fare with camping though, as I do not plan to use this for camping.Q: Do I need an American adapter plug?A: No. I have seen some dual hose units in the UK have the American plug but this one thankfully is designed for UK customers!Q: Will it work for large rooms?A: Probably not. I think anything larger than 15 m2, and this unit might start to struggle to keep up. My 13m2 room is being cooled effectively by this unit, but I do not get instant results when I turn it on. I usually pre-cool my room using max mode while I am out, then switch to a quieter mode when I am in the room. However! I speak as someone using this in a somewhat poorly insulated attic room with black heat absorbing tiles. If your room is well insulated, and you use both hoses effectively, then I think the scope of cooling can be increased quite substantially.Q: What's it like for tech nerds?A: This device has an app. Thankfully, the unit isn't tied to the cloud beyond firmware updates which is nice. I have own Wrieguard based VPN in addition to subnet routing using Tailscale so it is possible to control this device remotely anywhere in the world. The app looks sleek, and feels very polished. It does require an account to use which is a bummer but you can skip the app, after all, this unit is designed to work off grid and in remote areas where internet access may not be a thing!

Excellent product and very quick and easy delivery, lots of communication and updates, very easy to operate and highly efficient too, highly recommended

Faulty unit arrived. Looking on line there have been a few other people with the same issues. Error code 55, unit shutting off, and clattering compressor in night mode. I'll update my review after the replacement arrives.

Noisy compressor sometimes sounds like an air plane is taking off. I bought on release day no ecoflow are selling for less than I paid with a battery.
