Best Small Battery Operated Fans

The weather can get hot sometimes. Nowadays, it can get really hot that you become sweaty, sticky, and definitely uncomfortable. Oftentimes, this happens when you are outdoors without access to the air conditioner.

Such heat is not only uncomfortable but unhealthy too if it happens often. Sweating is the body’s mechanism of cooling off so at best we often need to find a way for the body not to even get that hot.

Fans are a fair alternative for getting cool in those hot days but an air conditioner is better by all counts.
With recent advancements in technology and its knack for making things smaller, fans are also going in that direction. They are getting ever so small, even small enough to slip into your pocket.

Now, we have a way to combat the unfair heat on the go and when air conditioners are not available.

What is a small battery operated fan and how does it work?

These are handheld fans that are powered by batteries. They vary in size but are often not bigger than 10 inches. Some are as small as your smartphone, while others are only just 3 inches.

This makes it easier for these fans to be carried and used almost anywhere. The convenience they offer is what makes them so popular.

A small battery fan works basically as any other fan. It has a motor that rotates the blades which redirect the air around towards you, hence cooling you.

Some of these small battery fans are designed in different ways, but this is basically the way they work.

What are some of the features?

There are different features you will find on different brands of handheld battery fans. The new versions keep coming with newer features.

Some fans have up to 4 different speed levels which let you choose how fast the blades will spin which in turn determine the airflow it outputs.

Some of these fans can rotate to create a directional airflow while others can just tilt on their base. Yet others are just stationary.

Some other features you might find in a small battery operated fan are:

  • LED lights
  • Fan heads that can rotate
  • Timing functionality
  • USB rechargeable
  • Doubles as a power bank
  • Multiple fan speeds
  • Misting fan
  • Variety of colors, etc.

Things to consider before making a choice

The beauty of battery operated fans is that you can take them with you wherever you go. They have versatile use due to their size and weight. We are talking about the small battery operated fans here so they are all small sizes. Here are some of the considerations you should make.

  1. Size – Even though this category is for small battery operated fans, they still come in different sizes. For the sake of mobility, you might prefer one that can easily slip into your pocket if you are not the type that carries a bag. There are some that are about 3 inches in size. If you carry a bag around often, you might want to opt for those ones that are about the size of your smartphone. If you all you need it for is to use at home then any of the 10-inch ones won’t be bad.
  2. Power – Don’t get carried away with size though, the larger the fan does not necessarily mean the more powerful. The power of a handheld fan largely depends on the motor that powers the blades. The motor fitted in a 5-inch fan from one brand just might be more powerful than that in a 7.5-inch variant from another brand.
  3. Battery life – These cordless fans are a choice item in our everyday arsenal. How long they stay useful comes down to their battery life. Quite a number of these fans are powered by 18650 or D-cell batteries, often lithium-ion. Some battery powered fans have up to 6000mAh, which is high considering the size. Most of them have less, though, but the important thing is to know that the higher the mAh rating, the longer the battery will power the fan. One other thing to note is that running your fan at high speeds will consume battery power faster.
  4. Reverse charging – Some of these small fans can double as a power bank. This means you can also use them to charge your USB devices. Those times you are not feeling hot, and you don’t need the fan, but your phone battery is down; you can juice it up. If this sounds like an interesting feature, you can look out for it.
  5. Dual power source – Yes, we know, they are called battery operated. That does not mean they can’t be powered by other means. Some battery operated fans can also be run via USB. The regular 5V USB port will often power these dual power source fans. That means your car charger, laptop USB ports, power bank, etc. can power the fan so you can enjoy it while saving battery.

Advantages and disadvantages

The most obvious advantage of the small battery powered fan is its size. This makes it usable just about anywhere. You can always pack it in your bag as a travel companion. You can take it with you on your camping trip, a fishing expedition, cycling, etc.

The fact that they run on battery too adds to their mobility and versatility. The dual power source variants can be used anywhere from your car to the library, office, at the beach, etc. Just plug it in a USB port and you are good to go.

It is ironic that the feature that is the most advantageous is also related to its disadvantage. The main disadvantage of battery powered fans is that they are only effective for one person at a time. The smaller variants are not even effective for one person as a whole, they are meant to cool the face which seems to have a chain reaction to the rest of the body.

Another disadvantage could be how often you will need to change batteries if it is not also powered by USB. To counter that, you might go for those fans that use rechargeable batteries so you won’t have to spend so much on batteries.

Now, you have important information about small battery powered fans and you also have a good idea about which features to go for. The next step is to read our detailed review of trusted products below.
