Best Portable Air Conditioner Reviews UK

Portable air conditioners are becoming very popular across the UK. Why are portable air conditioners growing in popularity? These come in various capacities and settings to cool and dehumidify a room, ranging from the simplest, minimalist models. From intricate ones with LED lights, multifunctions, personalized features you might want to have in a single device. You can find a wide-ranging assortment of these as they continue replacing the traditional central air conditioning unit, as well as fans. 

The main reason is the cost of buying the portable air con unit. The units usually come at a reasonable and reduced price if compared to permanent installations (or fans); there are no installation costs, they are easy to use and operate, and of course, highly mobile. They are small units perfect for a small office, urban living in studio and apartments, where the living space is limited. But you can also take them with you on vacation rentals, camping trips, or private smaller social events. 

Traditional central air conditioner units use much power to cool down the whole house, even if you’ve been currently spending most of your day in a single area, such as an office. The portable air conditioner unit makes it easier for you to move from room and room and take your device with you. Some of the models come with castor wheels, so you wouldn’t even have to pick it up and carry it around. But even if you did, they are usually lightweight, normally not crossing the 1kg mark even when completely full of water. It weighs even less if the water tank is emptied and it shouldn’t be hard to transport it, let’s say, taking a flight of stairs. 

If you prefer the central heating system, it might be handy to have a portable unit around in case your central AC has a breakdown before the repairs are done. 

The portable air con also has the potential to bring down the energy bills. Their power input is very low compared to air central units, and most of them are charged with USB cables, car chargers, or even power banks. Some of the devices also support batteries – although they won’t come with those, you can count on it only if you’re calculating your tap. 

As said before, their small side and lightweight makes them convenient to use while you are in the office, home or even travelling in an RV, travel trailers, or out camping. 

Unlike the Central AC systems, the portable air conditioners don’t need the condenser unit that hangs out over the window. Some have manual drain tanks and others a small hose that drains the condensate water. 

The portable air conditioners are also able to cool and act as dehumidifiers at the same time. Too much heat or moisture is unpleasant and overburdensome, especially with people with respiratory problems or small children. There’s always the possibility to use portable air conditioners when the air is cool enough but in case humidity is high, you can run the dehumidifier exclusively without using the fan function. 

The portable air-con is becoming an increasingly popular product, and its popularity will only keep increasing as people discover its value and more efficient models make it to the markets. We will look at various portable air conditioning units from the Amazon UK website. We will go through their technical specifications, why you should consider buying a portable air conditioner, and some analysis of the models that made it to this list.

Buyer’s guide

To make an informed decision when buying your portable air conditioning unit, compare different products from the same manufacturer and other manufacturers to get your ideal product. Here are some of the most frequent questions about portable air conditioners: 

Do all portable air conditioners need to vent?

Generally yes. Portable air conditioners need to vent warm air out of a window, a door, or a wall. Most of them come with a window kit or venting kit which has a hose with or without clippers of some sort.  Once you have decided where you want to put your portable air conditioner, you should just find the nearest window, door, ceiling, or an opening in general where you can place the hose. It needs to be outdoors/outside, though, since the hose will be exhausting hot air. 

Do portable air conditioners use more electricity than window air conditioners?

In general, not really. Portable air conditioners are very economical and some models work by charging or are battery-powered. Studies say these portable units consume one eighth of the energy needed for a central air conditioner to operate. 

Of course, this will depend on the size of your unit. Most of them are smaller in size and capacity, which will make them consume a lot less energy. Others are fit for larger spaces and require an operation at a full higher capacity. 

Are portable air conditioners energy efficient?

It depends on the product. We recommend you check the power rating for the product. Usually, that will translate the energy efficiency and how much power it needs to when it runs for long periods.  Keep in mind how many hours you will be running the unit per day. 

A lot of models come with an option for you to set the portable air conditioner to automatically switch off or go into rest mode after room temperatures are controlled, switching back on when needed. Some other products have smart sensor technology and will go to rest when optimal levels are reached, and to power back on when the room goes into less than optimal conditions.

Do portable air conditioners use a refrigerant?

Yes, they all use a refrigerant. The refrigerant is a gas or a liquid, depending on the technology the manufacturer chooses to use. This gas or liquid is able to quickly change physical states from a lower pressure situation to a higher pressure situation, shifting from liquid to gas or gas to liquid. 

Basically, what this process does is enables the machine to get heat from a room and transfer the heat outdoors through a hose. This helps the fan in it to keep pushing cooler air indoors. 

Are portable air conditioners more eco-friendly?

Yes. Firstly, they consume less energy than traditional units. Secondly, making use of refrigerants can be considered more eco-friendly since these gases (or liquids) are permanently kept in a leak-proof container inside the portable aircon. Conventional air conditioners tend to leak a lot of greenhouse gasses throughout their operating life-cycle. More advanced models and technology only use a fairly small amount of refrigerant, so that’s another plus. 

Can I lengthen the exhaust hose?

You can, if you want to, but it’s not recommended. Not only because it can cause leakages, but because the manufacturer might not follow up with your warranty since you made alterations to the product by yourself. We recommend you get in touch with your product’s manufacturer and ask customer service if they have an option for selling a longer exhaust hose. 

What size of air conditioner do I need (BTU level)?

The standard rule: approximately 215 BTU for each square metre of living space. But there are other considerations to make, for example, if your room is sunny, shaded, if more than two people are present in the room each time the fan is working, if it’s located in a basement or a kitchen. 

You can count 600 BTUs for each person, and add 4,000 BTUs if the unit is going to be placed in a warm room like a kitchen. 

For reference: units range on average from 7,000BTUs, 9,000BTUs, and 12,000BTUs targeting small, medium, and large cooling rooms respectively. 

For a more specific number, there is a large number of free online BTU calculators where you can estimate the best size fit for you and your household.
