Best Portable Mini Air Conditioners for Hot Summer Strolls in the UK

The Lonfenner Personal Air Cooler, with its chrome-treated housing, looks like the sleekest portable mini AC. But its defining characteristic is not that. Its defining characteristic is the spray humidification hole in the middle. With this hole, you can easily direct airflow and make the AC much more effective than portable mini models usually are. The unit lets you adjust the blowing angles 120 degrees, meaning that you're offered more positioning options. Because they're so adjustable though, these openings can be a little tricky to clean.

What's not tricky is the remote that's shipped with this portable AC. Using this remote, you'll be able to change the settings without scooching next to the unit. These settings include three speed settings and seven LED ambient light options, so you can create a romantic atmosphere or make the light a little more suitable to the scene.

Aside from these attributes, the model's not that different from most portable mini ACs, including its size (185 x 150 x 152 millimetres), weight (880 grammes), etc. Still, even with the slight differences that we have described above, this unit from Lonfenner proves the best portable mini air conditioner on the list.

The Beedove Air Cooler Fan looks a little less attractive than the model we have reviewed above but, besides that, this is an impressive product from multiple perspectives. To start with, the unit can reduce the temperature at least 5 degrees Celcius within seconds, delivering a refreshing breeze that spreads at least 5 feet (1.5 metres). To add more, incorporating an UV-C sterilisation tech, the AC works wonders killing invisible bacteria and microorganisms, producing a pure, bacteria-free breeze.

Settings-wise, the model lets you choose between 3 speed settings: breeze, cool breeze, and strong wind. You can also adjust the blowing angles 90 degrees, directing the output. These elements are not unique to this product but what's somewhat unique is the noise-block design that makes sure the noise levels do not reach above 68 decibels, keeping the unit quiet.

The DARMAI Personal Air Cooler is not as versatile as its more expensive peers but just as effective as those portable mini ACs that cost almost twice as much as this model. Generally speaking, this portable unit will have no issues reducing the temperature somewhere around 12 degrees, making the stuffiest, driest, least comfortable rooms not just bearable but even pleasant to be in. Choosing from three speed setting options, the unit will also let you adjust the airflow, with the highest setting producing a strong wind but without producing considerable noise.

Pulling warm air from the room through the evaporative water filter, the AC creates this nice personal space that's both cool and humidified, letting you add essential oils or ice into the tank so that you can accelerate the cooling speed. The refill opening is a little narrow, so you'll have to exercise a little finesse to do so but, with practice, the task will become a cakewalk. Lastly, you can adjust the blades, meaning that you can position the unit both above and below you and still have the airflow coming right at you.

In other words, dry office spaces and hot home offices with insufficient cooling will immensely benefit from the DARMAI Personal Air Cooler.

The ARESAT Mini Portable Air Conditioner, 2020 Upgraded looks upgraded, alright. Measuring just 170 x 130 x 130 millimetres, this is the most compact, space-saving unit within this lineup. Even the busiest, most occupied workspaces should be able to accommodate this mini AC without making considerable space sacrifices. To some extent, what's even more impressive is that the AC lasts 12 hours, whereas even those models that cost twice more than this AC usually cap at 6-8 hours.

Sure, unlike those models, this portable mini AC does not incorporate changeable LED lights but most people do not use them anyway, to this is not the biggest compromise. A little more upsetting is that the plastic is partially flimsy, so we would recommend exercising caution when transporting this unit.

Setting this drawback aside, we have nothing but good things to say about the model, including its foldable top handle that enables easy relocation and the supplied USB cable that lets you recharge the aforementioned high-capacity battery from any USB-enabled device, from power banks to laptops.

To sum up, the ARESAT Mini Portable Air Conditioner, 2020 Upgraded is something that you can even bring with you on a camping trip without worrying that the unit will remain useless half the time.

The Homitt Portable Mini Air Cooler has its upsides but pales in comparison to every other model within this selection, even if a little. The biggest issue we have with this unit is that its battery is only able to work for 4-6 hours, while every other AC that we have reviewed here lasts at least 6-8 hours. Aside from that, the plug is too close to where you pour the water in, so you have to switch it off before you're able to top up and you should still do so carefully.

That being said, again, the product has its upsides, with the biggest being the stain-resistant cotton filter. First, you can remove, wash, and reuse this filter for much longer than paper filters. Second, it is treated against antibiosis and mildew, filtering out most impurities, bacteria, and dust particles. Third and last, its pull-out construction lets you remove the filter with ease and clean it with matching ease.

Mirroring its more expensive counterparts, the model comes fitted with blades that you can adjust, adding extra placement options.

Without addressing the things that most portable ACs are offering (like its three speed settings and the USB-rechargeable battery), the Homitt Portable Mini Air Cooler is an affordable temporary solution to a hot temperature problem.
