Why Is My Disposable Vape Blinking?

As a rule, your disposable pen must not cause any trouble. These pens might not be very robust, but these use-and-throw devices serve their purpose well.

One of the reasons for buying these pens is that they almost need no care and cause no trouble. So, it is right to ask why is my disposable vape blinking since we all know that blinking in most instances indicates some error.

In this article, we will discover all the possible causes of vape blinking and suggest solutions to some of the common issues.

Battery Issues

If your disposable vape blinks, it is likely due to a battery error. In most instances, manufacturers program their devices so they start blinking if the battery is low, damaged, or not connected well.

A blinking light often indicates that the battery is running low. Most disposable vapes have non-chargeable batteries, though some might be chargeable.

Loose or improper battery connection can disrupt the power supply to the atomizer, causing the LED to blink. Ensure the battery is securely connected to the device. In such instances, blinking is irregular, pointing to a lost connection.

In some cases, excessive heat generated during vaping can trigger safety mechanisms in the battery, leading to blinking. Give your vape pen a chance to cool down if this happens.

Atomizer or Coil Issues

If it isn’t battery, then blinking is most likely due to some problems with an atomizer, or even most probably due to coil.

If your tank is empty or has insufficient e-liquid to cover the wick and coil, the vape pen will not fire, causing it to blink. In the case of disposable vape, it means that it’s time to order your next vape pen.

Although damaged coil may also cause blinking, these issues are extremely rare with disposable pens. Nevertheless, there are some chances, so keep in mind that coil damage may also cause disposable vape pens to start blinking.

E-Liquid Problems

These are extremely rare issues and may only occur if you buy some counterfeit product or untested product. In such instances, you may get disposable vape with very thick e-liquid due to high VG content. Or, it could also be due to the poor quality of the coil, resulting in a burnt coil and, thus, vape blinking.

Safety Features

These are generally present in more modern and premium vapes. They are to protect users from potential hazards, even if the risk posed by disposable vape devices is minimal. In such premium disposable vapes, blinking may indicate some malfunction.

There could be many causes for such malfunction, like short circuits. Check your atomizer, coils, and connections for potential shorts.

In order to prevent overheating, some vape pens will stop firing and blink when they reach a certain temperature. Allow the device to cool down before using it again.

Generally, experience shows disposable vape blinking due to some error occurs rarely. In most cases, the above tips may help resolve the issue. If the issue is not resolved, one may need professional help. Disposable vapes aren’t expensive and are not meant to be repaired, so in some cases, it may mean that you need to buy a new one.


A blinking vape pen LED light can be alarming, but it’s often an indicator of a solvable issue. By understanding the common causes, such as battery problems, atomizer issues, e-liquid concerns, and safety features, you can take the necessary steps to troubleshoot and resolve the blinking problem. Regular maintenance and responsible use of your vape pen ensure a reliable and enjoyable experience.
