An 80 – degrees Fahrenheit with full sunshine day in Seattle area definitely brings some uncomfortable to everyone. Some sitting-office people will envy you because you have a fan that actually cools you down with strong wind flow. Plus, it looks cool even you work outdoor.

I share the same uncomfortable on a hot day since my job is working outdoor in a UPS import/export hub. I experience the hotter air in the trailers because all the trailers sit under the sunshine for hours and hours. They wait for our team to import Canadian packages and then export to local Seattle hub and Portland hub. Once our team opens the trailer door, the internal flowing-out air feels like 90 degrees Fahrenheit ???

A personal fan definitely gives great help for the situation when you need a hand-free but still cool for outdoor activity.

USB Necklace fan cools you down and looks cool on you

How it works:

It very benefits when you wear this 8.8 ounces necklace fan for hours. At the beginning of the part-time job, or your outdoor job, you can wear this necklace fan for 6 hours of continuous working time without charging the fan. By pressing the wind speed button at low speed. Even the wind speed stays at the low level, the dual 1.5 diameters fan installed 7 blades keeps you cool until your break time.

And then, you come back to your outdoor job. However, the fan’s still running without taking a break unless you order it. When your body warms up again after the break, press the wind speed one more time. The medium wind speed produces more airflow for you. The 2000 mAh rechargeable 18650 battery lasts 4 hours long when the fan runs at medium level. The fan will turn off itself after 2 hours producing the high-speed airflow in order preventing over-heat.

  • The LED light might attract some mosquitoes in some foreign places.
  • When operating the fan wind with the light together, the battery can’t work well so long. While running two features at the same time, it kills the battery life quicker since it consumes more power.

Bonus tips: When you wear this cool USB fan, keep your neck straight. For ladies, be careful with your hair. If you don’t want trouble your hair stirred to the fan blades, you need to pull up all your haird-> and then wear this fan on your neck-> next just release your hair, let it flow attractive when you turn on the fan. Or simpler, you would look prettier when you wear this fan with your ponytail ? And some Asian people, why you don’t use this necklace fan to cool down your hot noodle/ramen soup?

Bonus how to use this 2-in-1 misting USB fan

After you unbox, it’s better you recharge this 2-in-1 misting USB fan right away. Since it doesn’t have much power for you to test out because the seller doesn’t charge it in advance for you. -> the ideal is letting it recharge fully.

For the full playing process after 3 hours recharged, you can prepare 400 ml cool water or any flavor tea (I mean the final tea water, not the tea bag. You can try to add the cool water first and then let the tea bag sit inside the fan’s water tank).

Next, pay a little detail here because the place for opening the fan cap is kind of close with the place for you to twist in order to pour the liquid into the water tank. -> Taking the two function buttons as the starting point. Above two buttons is the cap for open the fan and it’s allowed you to rotate 180 degrees only. When you can open the fan cap, you will see a small hole around 1/2 inch diameter. That is the output of water vapor for moisturizing.

Below the two function button is the cap for you to check the water tank. For this one, you will need to twist following the counterclockwise. Usually, if you see the cap include the cap fan, it means you have done correctly. If you feel it’s hard to open this fan water tank,…maybe something’s wrong.

And then, you just pour the prepared cool water or tea water. -> close the fan water tank’s cap-> turn clockwise direction and tight enough the water tank and the upper body.

Now, you just need to choose which function you want. Do you want the humidifier only? Or just the fan? Perhaps the combination two functions?
