The fan is an electronic device that has the main function as a cooler. The fan is driven by a motor in which there is a coil in series with the capacitor.
The working principle of the fan is to convert electrical energy into motion energy. Fan blades can rotate due to differences in air pressure between areas around the blades.
The motor contained in the fan will rotate the air behind the propeller forward so that circulation occurs.
Fans are starting to become unpopular because of the widespread use of air conditioners with a wider range of air distribution. However, now a portable fan has been created, which can be taken anywhere.
A portable fan is a types of fan that is not placed at one point such as a wall, floor, or ceiling.
Portable fans can be taken anywhere as long as the power is recharged or charged. Portable fans come in various sizes and battery life. Charging a portable fan can be done using a cellphone charger, or a special charger.
The invention of this portable fan certainly has its benefits, but it also has its disadvantage. The following are the advantages and disadvantages of portable fans
Advantages of Portable Fan

Portable fans are available in small sizes, which can be put in a bag to a rather large size to cool the room.
2. Save Cost

4. Multifunction
Besides being able to circulate cool air, some portable fans can be used as backup chargers or power banks for cellphones.
Some portable fans have a light, which is similar to a ring light so you can use it for video calls.
There is also a portable fan equipped with an emergency light. So you don’t have to worry when the power goes out and it gets too hot, because this fan can be used as an alternative.
5. Energy Saving
Besides being able to save costs, portable fans can save energy because they use less power. By saving energy, you also contribute to protecting the environment.

Make sure to choose a portable fan that feels durable, so it doesn’t get damaged quickly.
Disadvantages of Portable Fans
1. More Complicated Maintenance
Fan maintenance can be done by opening the components of fan, then cleaning the blades. However, for portable fans, the frame and blades tend to be difficult to open.
So it is very possible that the portable fan is not cleaned and there is a buildup of dust on the propellers which results in poor air quality.
The accumulation of dust on the fan blades will cause the blades on the fan to be unbalanced so that the fan will make sound when in use.
Also, if the battery starts to drain, you can replace the battery. However, for some fans, such as portable fans that can be charged, the seller does not provide spare batteries.
So when there is damage to the battery, there is nothing that can be done other than buying a new fan which of course costs more.
2. Not Durable
Portable fans can’t last too long, so when they break, you have to buy a new one. Most portable fans are easily damaged because the material is not as strong as standing or ceiling fan. So it is not uncommon for portable fans to be damaged immediately after falling or being hit.
3. The Air Produced is Not Too Cold
The small amount of power used by portable fans makes the air produced is not too cold. In addition, the size of the propeller that is not too large also affects the strength of the air circulated by the fan.
If you need a cooler that you can take anywhere, then a portable fan is the solution. You can choose various types and models according to your needs. Portable fans have been sold in many markets and online stores.
