We are in the middle of summer already. Just a few weeks more, the romantic season will start soon. Fall season specialist is the light cold winds which bring the romantic atmosphere. It’s the Autumn wind which flows the Summer hot, dry temperature away.

In the meanwhile, let’s take a look with Top 3 Rechargeable portable fan for Summer 2019. Even three fans are designed in the compact size, but all of them provide the wind, airflow strong enough to keep you cool.

I list those three fans following one order: about their recharging time.

The first fan needs 3 hours recharging. However, you will find this fan is more than your expectation. Even this Jesir rechargeable portable fan is small, suitable for airplane, but the manufacturer is proud about how powerful of their motor.

The second fan recharging time is about 4 hours long. It’s more suitable for young girls, young ladies since it’s Hello Kitty pink design 🙂 It’s cute. It’s powerful enough to keep all ladies in cool as need.

The last fan has a unique design. The fan has claws. You can clip the fan almost anywhere as long as it has about 1.5 inches in width. And it needs from 4 – 6 hours for the full recharge.

How do we determine the wind strength? RPM is the standard comparing for all fan motors. RPM is the acronym for Revolutions per minutes. With different RPM, the fan airflow speed varies. Those three fans have their own default RPM. All of them share one thing: all have three-speed levels.

However, the rechargeable battery is abnormal. Jesir default is a recharging 18650 Lithium-ion battery. With this type of battery, this Jesir fan has a larger capacity comparing with others. This Jesir fan has 4000 mAh. While others are around 1200 mAh – 2000 mAh – 2200 mAh – 2600 mAh. -> it means the performance time lasts longer.

  • You also can use the cellphone adapter -> plug into the normal wall-mounted electric circle because the fan still works well with 110 V or 220 V as a normal fan -> It means you can bring this fan everywhere in the world. As long as the electric takes place.

  • After full-charging, the performance varies from 5 hours continuous into 20 hours long depending on the wind speed you want to use.

Wind speed: this Jesir 2019 handheld fan has three-speed levels. When you want to change the speed, you will need to press on the button. Don’t worry because this fan has only one button in the middle body. It’s a one-press button. As you press one time, it turns on the fan at speed 1. -> press again, it goes to speed 2-> one more time, it goes to the speed 3 which is highest. It’s total 3 times pressing the button.

Speed 1 motor: 1800 RPM. -> around 26 km/h -> The wind at this speed has the effect moving small branches of the tree or dust, loose paper lifted

Speed 2 motor: 2500 RPM. -> around 36 km/h -> The wind at this speed has the effect: small tree in leaf begin to sway or flag fully extended

Speed 3 motor: 3200 RPM. -> around 46 km/h -> The wind at this speed has the effect: large branches tree shakes or umbrella becomes difficult to use.

  1. Thanks for this great post.  Oddly enough, I’ve been looking to get a portable fan that can be recharged.

    I can tell you now that fan #2 is out as I’m not into Hello Kitty styled items.

    The clip/claw is drawing me toward the Sky Genius option as I can pretty much clip it anywhere.  Still, the hand-held option of the Jesir is also appealing.

    Thanks again for this, now I just have to decide which one fits my needs best.


    P.S.  at the beginning of your article, RPM seems to be shown as RMP.  I thought you might want to know.

    1. Dear Scott 

      Thank you for leaving the comment and very appreciate about that small thing. I check it now and correct for the consistency 🙂

And some more upgrades with only 5 bucks extra. Learn more on Amazon

  3. Thanks for writing an article including three totally different fans. My daughter is always hot, so I know she would love one. I really like the Jesir brand fan. I love the fact that it has three speeds. My only concern is the battery. If the battery is irreplaceable, what happens if it goes bad? Is the fan of no use? Do you know if this is an issue with this type fan? Thank you so much!

    1. Hi Bonnie 🙂 

      Even the irreplaceable battery would go wrong, you can send a message directly to the seller. They will give you three options: replace with the new fan with same series and design; upgrades to the newest version 2019 about 5 bucks extra or complete refund your money 🙂 

      If you don’t bother about the battery issue, you can use the fan as the normal fan function by plug-in the USB cable into the adapter-> and then, plug into the AC/DC electric in your resident place 🙂 (like old school fan XD)

  4. Thanks for the comprehensive review! This is exactly what I need, as I have been looking for a good portable fan. 

    I like the Jesir 2019 fan as it is long lasting with the 4000 mAh battery and seems to be powerful enough for my needs. I also like the fact that it isn’t noisy. 

    I will be sure to check it out. Thanks for the recommendation!

    1. Wow, Joe 🙂 You are fast. You have been known what you want and what you need 🙂 Unlike some people who are still hesitant about everything in general life. Anyway, everyone has their own strength. It’s unfair when comparing.
