Why is My Disposable Vape Hitting By Itself?

Posted by Anastasia on Nov 17th 2023

Picture this: you're enjoying a relaxing vape session with your disposable vape, and suddenly, it starts hitting by itself without you even touching it. It's a strange and unsettling experience, and you might wonder, "Why is my disposable vape hitting by itself?" This article will delve into this unexpected phenomenon, exploring how auto-firing works, why your disposable vape might misbehave, and most importantly, how to prevent it from happening. So, let's unravel the mystery of auto-firing disposable vapes.

How Does Auto-Firing Work?

Before we dive into the reasons behind your disposable vape hitting by itself, it's essential to understand how auto-firing functions. When a vape device activates and produces vapor without user intervention, it is called auto-firing. In typical vapes, this happens when you press the fire button, signaling the device to heat the coil and create vapor.

In contrast, disposable vapes are designed to produce vapor only when you inhale through the mouthpiece. Sensors and circuitry within the device achieve this. As you inhale, the sensor detects the change in air pressure and triggers the heating element to vaporize the e-liquid.

So, when your disposable vape starts hitting by itself, it's essentially misinterpreting something as an inhalation, causing it to activate the heating element and produce vapor without your consent.

Is There a Reason Why My Disposable Vape Isn't Working?

If you find yourself dealing with a disposable vape that keeps hitting by itself, there are several potential reasons behind this unusual behavior. Let's explore some of the common culprits:

  • Malfunctioning Sensor: One of the primary reasons for auto-firing in disposable vapes is a malfunctioning sensor. The sensor responsible for detecting your inhalation may be overly sensitive or have a glitch, causing it to misinterpret external stimuli as inhalation.
  • E-liquid Residue: Sometimes, e-liquid residue can accumulate around the sensor area or inside the mouthpiece, creating a short circuit. This can trick the device into thinking you're inhaling when you're not, leading to auto-firing.
  • Manufacturing Defects: In some cases, auto-firing can be attributed to manufacturing defects. A flaw in the device's internal components or circuitry can lead to erratic behavior, including auto-firing.
  • Physical Damage: If your disposable vape has been dropped or subjected to physical stress, it might damage the internal components, including the sensor. Such damage can disrupt the normal functioning of the device and result in auto-firing.

The Best Way to Stop a Disposable Vape from Firing

Now that you’'ve identified the potential reasons behind your disposable vape hitting by itself let's explore how you can put a stop to this unwanted behavior:

  • Check for E-liquid Residue: Start by examining the mouthpiece and the area around the sensor for any e-liquid residue. If you find any, clean it thoroughly with a cotton swab or tissue. Ensuring that there's no moisture or residue near the sensor can help prevent false activation.
  • Inspect for Physical Damage: Carefully examine your disposable vape for any visible physical damage. If you discover any cracks, dents, or other issues, it's best to dispose of the device and replace it with a new one. Physical damage can compromise the internal components and lead to auto-firing.
  • Try a New Device: If you've ruled out residue and physical damage but your disposable vape still auto-fires, it may be a manufacturing defect. In this case, the safest solution is to discontinue use and replace the device with a new, functioning one from a reputable manufacturer.

How Can Auto-Firing Be Dangerous?

Auto-firing disposable vapes can be more than just an inconvenience; they can pose safety hazards. Here are some potential dangers associated with auto-firing:

  • Burns and Injuries: Auto-firing can result in the heating element reaching extremely high temperatures, potentially causing burns or injuries if it comes into contact with your skin.
  • E-liquid Leakage: Prolonged auto-firing can cause excessive heating of the e-liquid, leading to leakage and potentially damaging the device's internal components. E-liquid leakage can also be a safety concern.
  • Battery Overheating: Auto-firing can put a strain on the disposable vape's battery, causing it to overheat. In rare cases, this overheating can lead to battery venting or even explosion, which poses a severe safety risk.

Given these potential dangers, it's crucial to address auto-firing issues promptly and responsibly to ensure your safety and the longevity of your disposable vape.

Disposable Vapes: How to Prevent Them from Firing

Preventing your disposable vape from auto-firing primarily involves taking precautions and being attentive to its condition. Here are some tips to help you avoid this issue:

  • Store Properly: When you're not using your disposable vape, store it in a safe and dry place.
  • Inspect for Damage: Regularly inspect your disposable vape for any signs of physical damage. If you notice any cracks or defects, discontinue use and replace it.
  • Clean the Mouthpiece: Clean the mouthpiece regularly to prevent e-liquid buildup. Use a cotton swab or tissue to wipe away any residue. Keeping the mouthpiece clean can help maintain proper sensor function.
  • Follow User Instructions: Always follow the user instructions provided with your disposable vape. These instructions may include specific cleaning recommendations and safety precautions.


As a result, experiencing your disposable vape hitting by itself can be perplexing and potentially hazardous. Understanding how auto-firing works, recognizing the reasons behind this behavior, and taking the necessary precautions can help you prevent it from happening. Remember that safety should always be your top priority when dealing with any vaping device. If you encounter persistent auto-firing issues, it's advisable to discontinue use and seek a replacement from a reputable manufacturer. Stay safe and enjoy your vaping experience responsibly.
