Lidzopas 9000 BTU Portable AC Review: cheap way to cool a small room, with one big catch

I’ve been using this Lidzopas 9000 BTU portable air conditioner during a short heatwave in a small UK flat, mainly in a bedroom and a living room of roughly 15–20 m² each. I’m not an HVAC expert, just someone who was tired of sweating with useless fans and wanted something that actually cools the room. I’ll be straight: it does cool the air properly, but there are trade-offs, especially around noise and build quality.

When I bought it, the rating on Amazon was around 3.8/5, which already told me it wasn’t perfect. Some people were saying “great, way better than fans”, others were complaining that it’s very noisy and the plastic feels cheap. After using it for several days in different rooms, I’d say both sides are right. If you only care about getting the room cooler and don’t mind some racket, it gets the job done. If you’re picky about finish or you’re a light sleeper, you’ll probably get annoyed.

I used it mainly in the evenings and at night in the bedroom, and during the day in the living room while working from home. I tried all three modes: cooling, fan and dehumidifier. I also tested the sleep mode, timer and remote properly, not just once. I moved it between rooms a few times to see how “portable” it really is and played around with the window kit on a standard UK window and a patio door setup.

In this review, I’ll break down what actually matters in real life: how fast it cools, how noisy it really is, how annoying the setup is, and whether it feels like it’ll last more than one summer. I’m not going to dress it up: it’s a functional machine, not a pretty gadget. The big question is whether the compromises (mainly noise and cheap plastics) are worth the price you pay.

In terms of value, this unit sits in that budget to mid-range zone. Some buyers picked it up around £160–£170 on offer, which is quite cheap for a 9000 BTU portable AC in the UK. At that price, you can’t expect high-end build or ultra-quiet performance. What you’re basically paying for is “proper cooling at home without spending a fortune”, and on that front, it delivers. It cools small rooms well, dehumidifies, and has the basic features you’d expect: timer, remote, multiple modes.

The main thing you’re trading away is comfort in terms of noise and the feel of the materials. If you compare it to a more expensive unit from a well-known brand (De’Longhi, AEG, etc.), you’ll usually get better plastics, quieter operation, and a more solid window kit – but you’ll easily pay almost double. So the question is: is the price difference worth it to you? If you only need AC for a few hot weeks a year and you’re mostly using it in the living room or home office during the day, this cheaper unit makes sense. You’ll sweat less, and you won’t have emptied your bank account.

If, on the other hand, your main goal is to sleep with it running all night in a bedroom and you’re sensitive to noise, the value drops a lot. You’ll end up either not using it at night because it’s too loud, or using earplugs and still being slightly annoyed. In that case, it might be smarter to spend more on a quieter model or at least look for something with proven lower noise levels.

Overall, I’d say the value is pretty solid if you go in with realistic expectations: it’s a relatively cheap way to get real cooling in a small flat, but you accept higher noise, basic accessories, and average build quality. If you want something more polished and long-term, this won’t feel like a bargain, it’ll just feel like a compromise you might regret later.

Design-wise, this AC is pretty standard: a tall white box on four wheels with vents on the front and a hose connection on the back. Dimensions are roughly 46D x 89W x 40H cm, so it’s not tiny but still manageable in a small flat. It fits next to a bed or in a corner of the living room without dominating the whole space. There’s an LED display on top and a simple control panel with basic buttons. Nothing fancy, but it’s easy to understand without reading the manual for an hour.

The problem is more on the build quality side. The plastic feels thin and a bit brittle, especially on the accessories: the window kit pieces and the connector where the exhaust hose clips to the window panel. One of the Amazon reviewers mentioned the plastic cracking when they tried to screw it in, and I’m not surprised. When you handle those parts, you can feel they’re not very robust. If you’re careful and don’t over-tighten screws, it’s fine, but if you’re heavy-handed or plan to assemble/disassemble it a lot, you need to be gentle.

The main body itself feels a bit more solid than the accessories, but still “budget”. When you move it around, the wheels do their job, but I wouldn’t drag it over thick carpet or thresholds too often; it doesn’t give the impression it would like that. The hose is the usual flexible plastic type you see on most portable ACs. It’s not the worst I’ve seen, but it’s not premium either. It holds in place, but if you twist it too much, it feels like it could wear out or crack after a couple of summers.

In terms of pure looks, it’s neutral: white, fairly anonymous, the kind of thing you stop seeing after a while. For me, that’s fine – it’s a tool, not a design piece. But if you’re expecting something that feels solid and well-finished, you might be disappointed. The design is functional but clearly cost-cut. It does the job, but you need to accept that some parts feel flimsy and you’ll want to handle the accessories with a bit of care.

Let’s talk about the main trade-off: comfort vs noise. In terms of pure temperature, the unit does a decent job. In a 12–15 m² bedroom, it can bring the temperature down from around 27–28°C to about 22–23°C in under an hour if you set it to 18–20°C and close the door and windows properly (apart from the vent). You really feel the difference compared to a fan that just blows hot air around. Sitting or lying directly in the airflow is genuinely refreshing.

The catch is the noise. The 65 dB spec is not just a number on the box, you really hear it. Even on the lowest fan speed and in sleep mode, there’s a constant hum plus the compressor kicking in and out. It’s not a high-pitched whine, more like a strong desk fan combined with a small fridge running at the same time. For watching TV, working, or daytime use, I got used to it after a while. But at night in a quiet room, especially if you’re a light sleeper, it’s a problem. One Amazon review says the sleep mode “seems to do nothing”, and I kind of agree: it doesn’t magically make it quiet, it just slightly reduces fan speed and maybe cycles a bit differently.

In practice, I found two ways to live with it at night: either I let it run for 1–2 hours before going to bed to cool the room, then turn it off and sleep in the cooler air; or I keep it on but with earplugs. Without earplugs, I kept waking up each time the compressor cycled. If you’re used to sleeping with a loud fan or white noise, you might manage, but if you like silence, this is going to annoy you. So yes, it keeps you cool, but you pay for it with a fairly loud background noise.

Comfort-wise, the airflow is strong enough that you don’t need to point it directly at you to feel it. The auto-swing louvers help spread the cool air, which is nice. The remote means you don’t have to get out of bed to adjust the settings, which is actually useful when you’re trying to find a compromise between cool and less noise. Overall, comfort is good in terms of temperature and airflow, but clearly compromised by the noise level. If noise is a deal-breaker for you, this model is probably not the right choice.

Durability is where I’m a bit on the fence with this Lidzopas unit. I haven’t had it for years obviously, but based on the materials and the feel, I can guess a few things. The core components – compressor, main body, basic electronics – seem in line with other budget portable ACs. If you use it a few weeks per year during heatwaves and don’t knock it around, I’d expect it to last a couple of summers at least, probably more. It doesn’t feel like it’s going to fall apart immediately, but it also doesn’t give the confidence of a more expensive brand-name unit.

The weak point is clearly the accessories and external plastics. The window kit and hose connectors feel thin and a bit fragile. One reviewer mentioned plastic breaking when inserting screws, and I can see that happening if you tighten them too much or if you keep reassembling the kit. If you’re careful, you can avoid that, but not everyone is delicate when they’re sweating and trying to install an AC quickly in a hot room. I’d almost treat those parts like “consumables”: they’ll probably last a couple of seasons if you’re gentle, but I wouldn’t be shocked if something cracks down the line.

The wheels and handles are okay but not built like tanks. I wouldn’t drag it up and down stairs regularly. It’s best as a “move it between one or two rooms on the same floor and leave it there” type of device. The filter is easy to remove and clean, which is good for long-term use; if you actually clean it every few weeks during heavy use, that should help the unit run more efficiently and maybe extend its life a bit.

It comes with a 1-year warranty, which is standard but nothing generous. For a known brand, I’d be a bit more relaxed, but for a lesser-known brand like Lidzopas, I’d keep the box and receipts and test the unit thoroughly in the first summer to make sure everything works. Overall, I’d say durability is “acceptable for the price” but not reassuring. It’s not built to be abused or moved constantly. If you treat it as a seasonal tool, use it carefully, and don’t expect premium robustness, it’s probably fine. If you want something rock solid for heavy, daily use across multiple rooms, I’d look elsewhere.

Day to day, the unit is pretty straightforward. The controls on top are simple: power, mode (cool, dry, fan), fan speed, temperature up/down, timer, and sleep. The LED display is clear enough to read even from across the room. The remote mirrors the main buttons and works fine; I didn’t have any real issues with it not responding, as long as you point it vaguely in the right direction. That’s handy in a bedroom when you’re in bed and want to nudge the temperature or fan speed.

The 24-hour timer is useful if you don’t want it running all night or all day. I used it mostly to have the unit turn off automatically after a couple of hours at night. Programming it is basic but not complicated: set the hours, done. There’s no advanced scheduling or app control, but at this price point I wasn’t expecting smart home features. The sleep mode is a bit disappointing, though. It doesn’t really turn it into a quiet machine; it’s more like a small adjustment of fan speed and temperature over time. Don’t buy it thinking “sleep mode” equals silent mode, because it doesn’t.

Now, the window kit is where you feel the budget side even more. It’s usable, but not great. For standard sliding or sash windows, you can manage with a bit of fiddling. For windows that open outwards or for patio doors, expect some DIY: one reviewer had to build a wooden panel to make it fit, and I get why. The plastic panel feels a bit flimsy, and the connector between the hose and the panel is not the smartest design. If you move the unit a lot and keep installing/removing the kit, I can see those parts wearing or cracking. If you set it up once for the summer and don’t touch it, it should be okay.

In terms of mobility, the wheels do their job on hard floors; I moved it between bedroom and living room without too much drama. On carpets or over thresholds, you’ll need to pull carefully. It’s not ultra heavy for what it is (around 25 kg), but it’s still a chunky box. Overall, performance in daily use is decent but with a few annoyances: noisy operation, basic window kit, and a sleep mode that doesn’t magically fix the noise. If you’re a bit handy and patient with setup, it’s manageable. If you want plug-and-play perfection, this isn’t it.

On paper, this Lidzopas unit is a 9000 BTU portable air conditioner meant for rooms up to about 300 sq.ft (roughly 28 m²). It’s a 3-in-1 device: cooling, dehumidifying and fan. You can set the temperature between 16°C and 31°C, there are 2 fan speeds, a 24-hour timer, sleep mode, and it comes with a remote and a basic window kit. It uses R290 refrigerant, which is the standard eco-friendlier gas most recent portable ACs use.

The specs say the noise level is about 65 dB, which is already not quiet on paper. That number is important because a lot of people imagine “sleep mode” means almost silent. Here, 65 dB is more like constant loud fan/old dishwasher in the next room. It’s fine for daytime or if you’re used to background noise, but in a quiet bedroom at night, you’ll hear it clearly. The power draw is around 1300W, which is pretty typical for a 9000 BTU unit – not especially economical, not terrible either, especially if you only run it a few hours a day during heatwaves.

The brand is Lidzopas, which is not exactly a household name. That already set my expectations: I wasn’t expecting premium build or super polished design. It does come with the usual safety bits: overflow protection, compressor delay, auto-defrost, and a 1-year warranty. The filter is removable and washable, and it’s supposed to be self-evaporating so you don’t have to empty water constantly, though in high humidity you may still need to check it from time to time.

Overall, on paper it looks like a budget-friendly, no-frills portable AC: standard cooling power for a small room, basic functions, and some energy-saving options like the timer and sleep mode. Nothing fancy or smart-home connected, just a straightforward machine. The important part is how all those specs translate once you actually plug it in and try to sleep with it running two metres from your head.

On the effectiveness side, I don’t really have complaints. For a 9000 BTU unit, it performs like it should. In a small bedroom (around 10–12 m²), I could feel the temperature drop after 15–20 minutes, and after about 45–60 minutes the room felt properly cooler and less stuffy. In a slightly larger living room (around 18–20 m²), it still did the job, but you have to give it more time and keep doors closed. It’s not meant for big open-plan spaces, but for the size advertised (up to 300 sq.ft) it’s realistic.

The dehumidifier mode is also useful in typical UK humidity. The spec says up to 42L/day, which is the theoretical maximum, but in practice you just notice the room feeling less damp and heavy. If you live in a flat where the air feels sticky in summer, it helps a lot. The self-evaporating system means you’re not emptying a tank every hour, but I still checked the drain occasionally just in case. For me, it didn’t overflow or anything, so that part seems to work as stated.

The fan-only mode is basically a strong fan using the same air, so don’t expect magic there. It’s handy when it’s not hot enough to need full AC but you still want some circulation. Personally, I mostly stayed on cooling mode because that’s the whole point of buying this type of unit. The two fan speeds are a bit limited – I would have liked a third, quieter speed for night use – but the lower speed already reduces the noise slightly, even if not enough for everyone.

In short, on pure performance, I’d say it’s effective for small to medium rooms if you set your expectations right. It cools better than any fan, and the dehumidifying effect is a real bonus in muggy weather. It’s not instant AC like in a car, but after an hour you feel a clear difference, and during a heatwave, that’s what matters. If someone tells you it doesn’t cool at all, I’d suspect installation issues (badly sealed window, hot air leaking back in) more than the machine itself.
