For many people, smoking vapes has become a happy and integral part of their daily lives, and one of the pleasures of taking a break from work or meeting up with friends.
However, sometimes a vape device can go wrong and then the vape needs to let you know what’s going on. One way to do this is through a flashing blue light, and to help you understand better, in this article, we answer the question: Why is my vape pen flashing blue?
Why is my vape flashing blue?
Before we get into what the flashing blue light on a vape might mean. It’s important to understand that vapes are produced by a large number of companies that work in different ways.
No matter what type of vape you use. There is always the possibility that it could malfunction, and the vape needs to notify you if it does.
This can be done in a variety of ways, but one of the easiest ways is to add a flashing light to understand what it’s trying to tell you. You need to know what the frequency of the flashing or the color of the light might mean.
However, the market as a whole isn’t standardized and every brand uses a different flashing light. So a blue flashing light on a vape could be completely different from a similar flashing light on another vape.
Therefore, it’s impossible to answer what it means to see a flashing blue light if we don’t know what kind of vape we’re talking about.
Instead, what we can do is give you some examples that will help you figure out what your vape is trying to tell you.
Now let’s get started with some of the most common ways to explain a flashing blue light on a vape.
1. Disposable Vapes running out of juice or dead batteries
Disposable vapes are a convenient and inexpensive option for those who just want to enjoy vapes without having to worry about using and maintaining more complicated devices.
These vapes typically come with a small amount of e-liquid and are fully charged for immediate use.
Then, when the vape runs out or the battery dies. You simply throw it away and buy a new one – some brands will use a flashing blue light to tell you when you need to replace it.
Sometimes, if you leave it for a while, you might take a couple of puffs, but no more than two, as the vape is empty and the flavor may not be particularly pleasant, so it’s best to buy a new one.
Or, if you want to enjoy the convenience of using a disposable vape but don’t want to worry about replacing it too often, you can opt for a higher-end disposable vape, such as Zumo DT20000.
Zumo DT20,000 has an impressive, sleek and portable design with adjustable airflow. The dual Mesh Coil produces a clean and refined taste that maximizes the efficiency of the e-liquid. For some who crave bolder taste buds, the Dual Mesh Coil delivers strong and intense flavor, but at a higher cost.
The Zumo DT20000 combines nearly 20,000 ultra-long battery life, customizable flavor sensations, and an intuitive display. A high-quality and affordable design, and a never-before-designed 20 ML e-liquid capacity to show how disposable vapes can be powerful, customizable, and offer incredible value.
2. Capacity is “Medium”
Some vape brands (notably Vaporesso) use a blue flashing light to tell you that the power level has reached a certain level.
Specifically. Vaporesso vapes flash a blue light to tell you that the vape contains a medium level of power, i.e., more than 30% of power.
The blue light is an important signal to be aware of when using this vape.
This is because using a vape before the battery is completely drained reduces the long-term performance of the battery. Which means you will have to replace the battery sooner than usual.
To prevent this, when you see a blue light, you can take it as a reminder to charge your vape.
Another possibility with the same brand is that this means you are intentionally setting your vape to medium power mode.
The purpose of this mode is to consume less power than when the battery is fully charged, kind of like the low-power mode on a smartphone.
When you select this mode, the vape will notify you by flashing its blue light a couple of times.
3. Low cost
Another possibility, depending on the brand of vape you’re using, is that the indicator light flashes.
Of the majority of vapes that bring out different colored flashes. It’s more likely that a red light or red flash will be used to alert you that the battery capacity will run out, just as a green light is most commonly used to indicate that a vape is fully charged.
However, some simple vapes may use a blue light to alert you that they will soon need to be connected to a power source. If you can, check the instruction manual attached to your vape for the most accurate information.
4. Charging
Some vapes may emit a blue light that blinks slowly while charging.
This all means that everything is normal and your vape is charging.
When the vape is fully charged, the display light may change to another color (e.g., a constant green) to remind you that it is fully charged. Again, please refer to the user guide, if available, for detailed instructions on what the different colored indicator lights in your device mean.
5. Loose Battery
If you try to take a puff on your vape, nothing happens, and then you see a flashing blue light. This usually means that the connection between the battery and the vape is loose.
In this case, you can first make sure that the two parts are properly screwed together so that you can continue to smoke your vape normally.
If that doesn’t help, you can also consider opening the vape and inspecting the inside to see if the vape or battery is contaminated with dust, stains, sticky substances, or dry vape liquid
The connector is dirty; you can fix the problem by wiping it with a cotton swab and a drop of topical alcohol. If not, the connector may be bent in place.
To fix this, you can try lifting or bending it back into place with a small flathead screwdriver. Then, you can screw the battery back into the vape and see if the light is still blinking.
6. Overheating
A blinking blue light could mean that the battery is overheating. The vape or the battery may feel hot. In this case, you should stop using it immediately, remove the battery, and put it in a safe place to cool down.
7. Short circuit
Blinking lights on your vape (including blue blinking lights) can mean a short circuit, especially if your vape is no longer working properly.
A short circuit can be caused by damage to the internal parts of the vape caused by dropping it. If you use disposable.
8. Smoking for too long
Finally, another possibility is that you are smoking your vape for too long between each puff.
Most vapes are designed to automatically shut off if you smoke for too long, and may be accompanied by a blue blinking light to let you know what’s going on.
At least when this happens, the answer is simple – you just need to shorten each vaping session!
There are many possible explanations
As we’ve seen with vapes
Therefore, the best way to find the answer is to refer to the manual to understand how to interpret the meaning of the flashing lights on your e-cigarette.
