Quick answer
Neck fans charge by connecting the fan to a power source with a USB-C cord. Most come with a cord and a rechargeable battery, take 2 to 4 hours to charge, and last 2 to 8 hours on a full charge.
- Plug the cord into the fan, then into a USB wall adapter or computer USB port.
- On models with a charging light, it turns solid, green or off when the battery is full.
- Charge the fan while awake and nearby, and unplug it once it is full.
Neck fans are wearable, lightweight fans that hang conveniently around your neck while you work, exercise, or spend time outdoors.
If you are thinking about getting one, you might be wondering how to charge neck fans.
This is how you charge neck fans:
You charge neck fans by connecting a neck fan to a power source using a USB-C cord. Neck fans come with USB cords and rechargeable batteries. Neck fans take 2-4 hours to charge and last between 2-8 hours on a single full charge. Recharge your neck fan when the battery is getting low.
How To Charge Neck Fans (Step-by-Step Instructions)
The most common way to charge neck fans is by USB. Most neck fans come with a USB-C cord and rechargeable internal lithium-ion battery.
However, it’s a good idea to check with the manufacturer of your particular fan before you purchase.
Let’s walk, step-by-step, through the simple process of charging your neck fan with a USB cord.
Follow these instructions if your neck fan is charged by USB cord:
- Plug the smaller end of the USB-C cord into the port on the fan.
- Plug the other end of the cord into a USB wall adapter or a computer USB port. Use the cable supplied with the fan where you can.
- If your fan comes with a tiny light display, a light will turn on (and may begin blinking) when the neck fan is charging.
- Once the light turns off or turns solid (i.e. no longer blinking), the fan is fully charged.
It’s a good idea to purchase a backup USB-C cord so that you can charge your neck fan if you lose one of the cords.
How Long Does It Take To Charge a Neck Fan?
Most neck fans take an average of 2-4 hours to charge.
Some neck fans charge faster and some charge a bit slower. Each fan is slightly different.
The bottom line is that different neck fans take different lengths of time to charge.
Here is a quick table of how long it takes to charge popular brands of neck fans:
| Neck Fan | Charge Time |
|---|---|
| JISULIFE | 2.5 to 3.5 hours |
| FrSara | 2-3 hours |
| Sweetfull | 3-4 hours |
| Veamor | 2-3 hours |
| Torras Coolify | About 2.5 hours |
How Long Does It Take To Charge a Neck Fan for the First Time?
Many neck fans come pre-charged at delivery.
In other words, the manufacturer probably charged your neck fan before boxing and sending it to you.
However, the fan is not always fully charged when you get it.
Some neck fans work right out of the box, but a full charge before the first outing is still a good idea.
How long does it take?
Expect to wait for 1-2 hours of charging before you are able to use your neck fan for the first time.
How Do I Know When My Neck Fan Is Fully Charged?
In some models, a blinking light (or series of lights) on the fan will turn solid when the fan is fully charged.
You want to see this pattern of blinking-to-solid.
Other models feature a solid red light when not fully charged and a solid green light (or no light) when fully charged.
If your fan has this light feature, look for a green light (or the red light to turn off completely).
For example, here is a neck fan on the charger:
Some neck fans have a row of LEDs or a small digital display that shows the battery level.
Other neck fans have no light indicator and you will just have to wait a few hours until the battery is full to know it is charged.
Charge your neck fan while you are awake and nearby, and unplug it once it is full. The US Consumer Product Safety Commission advises against charging lithium-ion devices while you sleep.
How Long Do Neck Fans Last When Fully Charged?
Most neck fans will run for 2-8 hours on a single full charge.
Three main factors determine how long your neck fan will last:
- The price of the fan
- The speed setting you use (most neck fans come with 3 settings)
- The power of the fan itself
The less expensive fans usually run out of charge faster than the higher-priced fans.
The charge time also depends on how you use the fan. If you keep your neck fan blasting at the highest speed, the charge will run out sooner than if you keep your fan at the lowest speed.
Fans that cool you the most use more power so they deplete their charge more quickly.
Here is a chart comparing the average length of a fully charged neck fan:
| Neck Fan | How Long Do They Last? |
|---|---|
| JISULIFE | 4-16 hours |
| FrSara | 4-10 hours |
| Sweetfull | 4-10 hours |
| Veamor | 3-8 hours |
| Torras Coolify | 2-8 hours |
How Often Do You Recharge Neck Fans?
Recharge your neck fan when the battery is getting low.
The frequency of recharging is determined by how and how often you use your neck fan:
- If you use your neck fan all day at work, you will probably recharge it every day.
- If you use your neck fan while you exercise for 30 minutes a day, then you can likely go 2-3 days (or longer) without needing to recharge.
- If you use your neck fan on the highest setting, you’ll generally need to recharge it every day (or after every 2-4 hours of use).
A good habit is to recharge your neck fan in the evening while you are still up, then unplug it once it is full.
Can You Use a Neck Fan While It’s Charging?
Yes, you can use most neck fans while they charge.
However, most neck fans charge faster when they are not in use. If you don’t absolutely need to use your neck fan while it’s charging, it is better to avoid it.
Check your manual too, because not every model supports running while it charges.
Another thing to think about is how you use your neck fan.
If you use it while working at your desk, then you should have no problem. But if you use your neck fan while moving around, you might accidentally yank the fan’s USB cord out of the outlet, damage your fan, or hurt yourself.
Therefore, only use a neck fan while it is charging when staying in one place.
What’s the Quickest Charging Neck Fan?
Charge times are similar across the main brands. Torras says its neck fans usually take around 2.5 hours to charge fully, and JISULIFE lists 2.5 to 3.5 hours depending on the model.
Torras Coolify is one of the more expensive neck fan brands.
What’s the Longest Lasting Neck Fan?
JISULIFE neck fans are among the longer-lasting options. The maker lists up to about 16 hours on a single charge for some models.
That may surprise you because it is not the most expensive fan.
However, there are a few reasons JISULIFE usually lasts longer than other fans.
The main reason is that it is a less powerful fan. That does not make it a bad fan.
It is a good overall neck fan for general purposes.
It is also budget-friendly with lots of positive online reviews.
It may not blow you away with cooling power, but it can get the job done. You’ll need to fully charge the fan and keep it on the lowest setting to make it close to 16 hours.
You can also use other neck fans at a lower speed to maximize their charge life.
After all, most people don’t use a neck fan for more than 8-hours straight.
Final Thoughts
If you take care of your neck fan, it will take care of you.
