Best Portable Mini Air Conditioners for Hot Summer Strolls

This one is a desktop personal space cooler, although you can, of course, take it to a picnic or some other outdoor outing with friends and family to cool down your surroundings a bit. The best thing about this model, though, is that it's geared towards use in a room.

Generally, small portable devices like this one have but one function—to cool down space. The price they are sold at rarely warrants much more. This model, however, can not only cool, it can humidify and, what's important, purify the air you breathe as well. Maybe not much and not for a large room, but set it right beside you on a desk and it will make the immediate environment a lot better. For the very same reason, this model is considered the best personal cooler to have for when you sleep. It is virtually noiseless and its selection of colorful backlighting options will soothe you after a stressful day at work. You can set a single color to accompany you drifting into dreams or choose to have a cycle of interchanging colors. If lights disturb you instead of calming, though, the backlight can be turned off, too.

The control here is also easy: you have 3 speeds to choose from depending on how hot it is in your room. To have the air humidified, simply pour water into a special tank; when full, the tank is enough for approximately 8 hours of operation so your healthy sleep won't be interrupted by air stiffness and dryness.

The Skyocean handheld mini portable air conditioner is more than it looks. Inside the miniature body, besides the means to cool yourself and a bit of space around you, there is also a 6000 mAh power bank from which you can charge your gadget when the need arises (which it always does). Two to three extra charges for your iPhone is not bad!

As for the actual designated use, i.e. cooling, it does a remarkably good job considering its size and price. The fan has three speeds, low-medium-high, so there is some selection for you here. We'd like to point out that even at the highest speed, this model is pretty quiet and won't disturb you from working or talking to your friends. It is small enough to fit in your jeans pocket, let alone a handbag or a backpack, and it will work for solid 12 hours, at least at the low setting. The more powerful modes will strip the time off a little but not much, it will still be enough for an average day, at the end of which you can charge it for the next one, rinse and repeat. (Joking! Please do not rinse it!)

The only feature some customers might wish to have which is not present is that it is a fan only, there is nothing inside to cool the air, this USB air conditioner only circulates around the air it has access to.

The model is offered in white and in black-and-blue.

First and foremost, this is stylish! Bright colors will go splendidly with the summer-ed up streets. Purple, pink, green, and blue—just the colors to suit the summer mood, although if you lean to the stricter business style, there is a black-and-white model offered as well.

This small portable air conditioner from MiNi COOLi is a budget model, it is cheap even for the type of devices that are not exactly expensive in general. The reason for that is that it is fairly basic. The cooler has a single mode and its battery does not make it a very strong competitor for long hours of use. However, it has its own benefits besides the cute design.

Firstly, the single mode here offers more than decent results, cooling the air 3 to 5 degrees, a good enough number for a handheld mini personal fan. Secondly, here you can adjust the angle of the airflow. Not much, maybe, considering the overall size of the cooler, but it doesn't hurt to have the options.

The fan has a little stainless steel stand, which will enable you to use the device as a tiny desktop cooler. And if you drop some essential oil on the sponge inside intended to actually cool and humidify the air, you can create a special atmosphere around you in the room. Just remember to take the sponge out before you wet it or add oils.

The unusual shape of this handheld mini portable air conditioner piques curiosity right away, which is a plus for some users. It does have blades but they are hidden inside and pose no danger when the fan is working like it is sometimes possible with similar items. Therefore, you can even use it to cool a stroller or simply give it to your kids. It is not the smallest model on the market but it is compact enough to fit into a handbag. It is also pretty comfortable to hold in your hand or hang on your belt with the attached strap. Or it can be placed on the desk since it has a flat bottom.

The model utilizes an ultra-quiet motor to draw in the hot air from around it and pass it through a moisturized sponge inside. As a result, you receive some 30°F cooled and freshened air blown in the direction you need. The direction can be adjusted to some degree (90° to be precise) thanks to the rotating "head" from where the air blows.

One of the best features of the WoneNice that makes it entitled to be included in our best personal cooler list is that it can be powered both from a USB cord and 4 AA batteries. So when you're on the go, you use the batteries and the fan provides you up to 5 hours of cooling. When at home or in the office, plug it into your laptop's USB port and enjoy continuous operation. Besides the cooler and the cord, in the package, you will also get a small bottle for water to moisturize the sponge. It is a generally good budget option for hot dry climates.

A small rechargeable USB air conditioner by the ThreeH offers very little in terms of extras, it is quite basic and that is its greatest asset, probably. It is one of the smallest and the most lightweight models you will find on the market, mere 0.2 lbs and a little over 4" by the longest side. It only has a single mode (or speed) at which it blows the air but the speed is good, you'll have several degrees down in temperature right away (more if you freeze the sponge after moisturizing it) and will be able to enjoy it for approximately an hour and a half, maybe two, before you need to recharge it. All in all, it may be nothing to write home about, it is true, but check out the price, it's cheap to the point of ridiculous.

The model is the best personal cooler for commuting to work/school or for a summer shopping spree with a stop at a cafe to grab a cup of iced tea or coffee. There is a lanyard to carry the cooler on your neck or belt and a tiny T-shaped stand at the back to set it on the table as you relax and scroll your Facebook feed. And if you find the working time lacking, you can charge the fan from just about any USB-enabled energy source, be it your netbook, a solar charger, a power bank, or a car charger. There are three colors available for the housing.
