Vape pens are a less expensive alternative to tobacco cigarettes, plus they have a more pleasant smell. That is why vapers are often allowed to use these devices indoors. The best thing about vape pens is that they are convenient and easy to use.

Sometimes, vape pens start flashing, and you have probably wondered at least once – Why is my vape pen blinking? Be prepared that these devices often have multiple lights in different colors, including red, blue, and green. They blink for various reasons, including the most common issues with the battery. Let’s see.

Why Is My Vape Pen Blinking?

The causes of this problem can vary and often depend on the device model you have. Let’s check a few common reasons for vape pen blinking.

1. Low battery

The empty battery is the most common cause of vape pens blinking. If the flashing is low, you only need to recharge the battery and continue using the device. Never use your vape pen during this process because turning it off is the best thing to do.

In most models, red light flashes during charging and turns off when the battery is full. Eventually, the color of the light change from red to green. If the battery is dead, the only thing you can do is buy a new one. It is different with disposable devices, which you can only replace.

2. The battery is 100% charged

Just like when the battery is dead or low, vape pens can start blinking to confirm that the battery is 100% charged. At that moment, you can remove the device from the charger.

3. Battery overheating

Overheating of the battery can happen for several reasons. These are exposure to high temperatures and direct sunlight, excessive use, and overcharging. In those situations, you can notice that the battery is hot.

So, it is necessary to remove it from the device to avoid the risk of fire or explosion and let it cool down to room temperature. If the battery is damaged, you can notice leakage. The only thing you can do in such a situation is to throw it away because it is unsafe.

4. Dirty battery

When the battery is dirty, it can adversely affect its connection with the atomizer and cartridge, causing improper device operation. In such a case, you can notice blinking that stops after cleaning.

5. Connection issues

The vape pen can blink when the battery is incorrectly installed and connected to the device parts, resulting in insufficient battery charging. That problem often happens to beginners in vaping, and the solution is to reinstall the battery correctly.

6. Wrong components

The device reacts by blinking when it encounters incompatible components. It could be a wrong battery with insufficient power or a cartridge designed for a different model. Likewise, a coil resistance level that is too low for the particular vape pen can also cause blinking.

7. Improperly installed tank and atomizer

The vape pen blinking can also originate from an improperly placed atomizer and tank. The light should stop blinking after you remove the tank and atomizer and correctly reinstall these parts.

8. Low E-juice level

The low E-liquid level can be another reason for blinking. Be careful if that is the case because vaping in this situation is not harmless and can damage the battery and the coil due to overheating. Filling the tank with juice can solve the problem and turn off the light.

9. Overused vape pen

Some vape pen models blink due to intensive use. Frequent puffing can activate the heater shut-off function, which many models have. You can solve the problem with shorter puffs or longer pauses between them.

10. Burnt coil

The coil can wear out after using the vape pen for a long time. The problem manifests in reduced steam production or its complete absence. In that situation, the device can blink to warn of an existing issue.

11. Stuck activation button

Accumulated dust or dirt can stick the activation button on the vape pen, which is one of the reasons for blinking. When you clean the area around the button, you can expect blinking to stop.

12. Safety features

The blinking light usually warns of a problem with the vape pen, and most devices have this safety function. By heeding these warnings, you can react promptly and look for a solution in the user manual.

Reasons for Brand New Vape Pens to Blink

Sometimes, even new vape pens blink even though they shouldn’t. Here are some possible reasons for that to happen.

1. Locked device

Most new vape pens are locked in the packaging. For this reason, the device often starts flashing as soon as you try to use it. However, it will stop as soon as you turn it on by clicking the activation button.

2. Factory malfunction

There is a real possibility that a brand-new vape pen is damaged. It can be a factory problem or occur during shipping. In this case, E-liquid can quickly leak into the battery compartment during transport.

Regardless of the damage caused, it is best not to use such a device. Take a video and pictures to document the problem and contact the seller with a request to replace the device with the bill as proof of purchase.

There is a high possibility to get a new device if the manufacturer is reputable. Unfortunately, many online sellers ignore complaints, meaning your only option is to buy a new vape pen from a more trustworthy dealer.

3. Empty battery

Although some manufacturers sell devices with a fully charged battery, this is not a binding rule. Therefore, the vape pen can blink due to an empty battery.

What Does the Blinking Color Mean?

Vape pens blink in different colors, and each color has its meaning. However, it depends on the manufacturers, who often have unique coding systems for a particular model. Although it is best to look for a precise description of the colors in the user manual, here is what the individual colors most often mean:

1. The vape pen blinks green

If the device blinks green while you use it, it usually means its battery is more than 70% full. On the other hand, the same blinking during charging indicates the vape pen battery is 100% full. However, a green light on some models can mean:

• The vape pen is damaged
• The battery is empty
• The device has a connection problem

2. The vape pen blinks blue

Depending on the model, the blue color can mean a few things, such as:

• The vape pen’s battery is half-charged
• The battery is empty or damaged
• The device lacks E-liquid

3. The vape pen blinks red

Red color has the same meaning in all vape pen models, without exception. When your device blinks red, you can be sure the battery is empty, and it is time to charge it.

4. The vape pen blinks purple

This color has a non-standard meaning, so you should be familiar with the model you use. Depending on that, the purple light can mean:

• The cartridge is connected too tightly
• It warns of the device’s short circuit
• Vape is locked
• The vape pen has the wrong type of capsule

5. Constant light

A differently colored steady light has a different meaning than a blinking one. You can expect that red, blue, and green lights indicate the device’s voltage level.

What Does the Blinks Number Mean?

The meaning of the vape pen blink number depends on the model. The user manuals usually contain the best explanation, but here are a few possible reasons why the vape device typically blinks more than once.

Vape Pen Blinking 3 blinks

There are several reasons why a vape pen blinks three times. In some cases, the device signals it is switched on. On the other hand, it is a sign in some models that the vape pen is about to turn off. Besides, three blinks can also show a connection problem between the E-juice and the battery.

Vape Pen Blinking 4 blinks

One of the reasons for this blink number is a problem between the battery and the tank, which you can solve by wiping the connector. Likewise, it can indicate an issue with inadequate atomizer coil resistance.

Vape Pen Blinking 5 blinks

In some models, five blinks are a sign of a weak battery, but they can also indicate an issue with the activation button. As these problems can burn out the coil, some devices turn off automatically after eight seconds.

Vape Pen Blinking 10 blinks

This sign is related to the device’s electronics. The possible issues include low voltage due to the accumulation of dirt on the connections, improper vape charging, and a weak battery.

Vape Pen Blinking 15 blinks

The usual voltage the vape pen works on is 3.3 volts. If it is lower than that level, the device will indicate the problem by blinking 15 times.

Summary

There can be several reasons why vape pens blink. Although blinking typically indicates minor problems such as an empty battery, low E-juice, and dirty components, sometimes the problem can be more serious.

For instance, it can be an overheated evaporator or a damaged coil. Therefore, it is best to return a brand-new device that flashes immediately after turning it on to the seller and ask for a new one.
