Mini fan: varieties and subtleties of choice

On hot working days, the mini fan becomes the only salvation for those who catch cold after turning on the air conditioner. Such devices have become a salvation for many people and therefore have gained amazing popularity.

The small fan market offers a wide range of choices that are continually increasing.

Below are the most popular and common models.

• USB fans. Even every preschooler knows what a USB port is nowadays. Such fans are powered by laptops, computers, or from a network with a special adapter. They are characterized by a relatively long service life and very low energy consumption. Most often they are placed on office tables. Models on clothespins are very convenient and popular.
• Battery powered pocket fan. The cordless fan does not require an electrical outlet, making it mobile and doubly convenient. Most often, such a device is needed on vacation or travel.
• Bladeless models. It sounds incredible, but such models have gained popularity in the past few years. The principle of operation is simple: air is drawn in by the bottom of the device, after which it is distributed over a slot located along the diameter of the ring. Such models are silent, safe, durable, but also not cheap. Available both on a battery and with a USB port. This device is easy and pleasant to use.

• Noise level. Of course, the noise from a small device is much less than from a large one. Nevertheless, it is there and can be annoying at times. As a rule, the standard noise level for all such devices is 40 dB, and sometimes 30 dB. Such information is contained in the instructions or on the packaging.
• Power. A portable mini-fan cannot have high power due to its size. Power is a rather important factor, as it determines the entire functionality of the fan, because the more power, the better the device works. Typically small devices have a wattage of about 5 watts. The maximum value for a portable device with batteries is 12 watts. The voltage is 5 volts.
• Other functions. A backlight, power regulator, timer, ionization or humidification function can be added to the fan. If the buyer likes non-standard things, then a model, for example, with a drive or other additional functions, will be very much to his liking. Also in stores you can find models with a non-standard design in the form of bunny ears and other interesting details.

It is very easy to make a purchase for such a mini-device, but it is also easy to make a mistake with the choice and quality of the product. To prevent this from happening, you need to be prepared in advance to take into account some additional points.

• Stability. This can be a problem for small appliances. If the device is purchased for the office, where there will be no time to be distracted by an unstable structure, then it is better to opt for a model with a clothespin.
• Integrity of parts. If there is damage to the case, then it is definitely not worth purchasing such products. The likelihood that the device will not break or work properly is quite low.
• Strong heat. When buying, you need to turn on the device in the store.If it becomes hot in a short period of time, then the purchase should be abandoned.
• Low price. Such a product, like any of its kind, is not distinguished by either quality or long service life.
