Why Is My Disposable Vape Pen Blinking?

Disposable vapes are slim, typically cylindrical pieces of tech that create unforgettable nicotine hits and bursts of flavor. Disposables are by far the easiest vaping device on the market. Forget prep time and customization options. These slimline, featureless electronic devices are designed to be used straight away.

Like any electronic device, disposable vapes can crash. If your disposable vape blinks, you are just one of the thousands of vapers who have to search the internet for answers. Even the best disposable vapes are prone to problems. Luckily, we’ve been there, done that, and bought the t-shirt.

Reasons for Disposable Vape Pens Blinking

Did you know about disposables blinking before you started vaping? It is not uncommon for new vapers to feel stumped when their device suddenly starts flashing, especially if they have opted for a simple disposable vape pen. Disposables tend to have very few light-up features, which makes this problem all the more worrying.

The truth is that it happens every day, but what causes blinking lights? Some vape gurus claim that a blinking light is always an electronic fault, but this is not the case. Keep reading to get the real answer to the popular search query ‘why is my disposable vape blinking?’

Disposable Vape Blinking - Dead Battery

Other reasons why your brand new disposable vape’s not working? Don’t worry – we’ve got solutions.

Dead Battery

The most common reason why vapes start blinking is the battery. Have you lost track of the last time you charged your vape pen? Was it more than a few days ago? The chances are that the battery is dead, and the handy in-built flashing light feature is warning you that you need to plug in.

Low-battery lights are more common for rechargeable devices, but some disposable brands also include this helpful feature.

Low Battery Solutions

The solution to low battery power is simple; just plug it in. Most of the time, manufacturers put the charge port in a visible, easy-to-find spot. You might find it on the side of your device or even on the bottom. That being said, charge ports can be hidden under a screw top or a rubber plug. If you are struggling to find it, read the user manual that came with the device.

If you are impatient, buy a mod device that allows you to switch dead batteries for fully charged batteries. A good example is a lithium-ion battery, which is compatible with many vape devices. You can simply dispose of these batteries and insert new ones into your pen. This is the quickest and most seamless way to solve your blinking light issue.

Of course, a lot of disposables are not designed for multiple uses. If you can’t find a USB port anywhere on your device, the likelihood is that it isn’t rechargeable.

Low E-liquid

Is your disposable blinking? Still? It might have run out of e-liquid. It is difficult to spot when electronic devices are low on vape juice, especially if they are simple disposable vape pens. Whereas advanced mods tend to have a transparent section that allows vapers to see into the tank, vape pens tend to have simple, featureless exteriors.

New vapers are more susceptible to the dreaded empty tank. As you become more attuned to your e-liquid usage, you will be able to predict when your tank is running on empty.

Low E-Liquid Solutions

So, you’ve realized that your e-liquid is running low. It’s time to fill up with your new favorite vape juice.

When it comes to disposables, refilling is easy. It is just a case of unscrewing the fill port, squeezing your e-liquid into the tank, and screwing the lid back on again.

Some brands use rubber stoppers instead of caps. Just remove the stopper and complete the same process. Refilling an open-system pod-based device is just like filling a traditional tank.

If you have a closed-system pod-based device, you won’t be able to refill your vape juice. Closed-system pods are better known as pre-filled pods. As the name suggests, they come pre-filled with vape juice and can’t be opened or refilled. Simply throw away your empty pod and slot in a new one.

Disposable Vape Blinking - Puff Timer Limit

Puff Timer Limit

This is one of the lesser-known disposable vape mechanisms. 99% of disposable vape pens are fitted with a puff timer limit. Each time you take a puff, the atomizer coil and the battery produce heat. If they produce too much heat, the circuit will overload.

A blinking light could be an attempt to tell you that your circuit is overheating. When your disposable vape overheats, it could have a serious impact on the wattage and airflow. Even worse, your device could start to produce smoke and even sparks. Whatever the outcome, it is not safe to leave a disposable blinking for too long.

Puff Timer Limit Solutions

The easiest way to solve this problem is to give your disposable vape a cooling-off period. Put your vape down, step away, and come back when it has stopped blinking.

If you attempt to puff on your vape pen while it is still blinking, you will just prolong the problem. In this situation, the best solution is to do nothing. It might feel tempting to take a few more puffs, but remember that the in-built puff timer limit is for your safety.

To avoid the problem in the future, space out your drags or take fewer puffs. You can get the same kick from fewer puffs if you make them longer or increase the nicotine strength in your e-liquid.

Incompatible Attachment

People who prefer simple disposable vapes typically don’t have to worry about incompatible attachments. This problem is more common among people who buy advanced, customizable sub-ohm kits and mods. However, the term attachment doesn’t just apply to fancy, swanky new tech. It also includes standard recharging ports and cables.

Did the indicator light start flashing when you plugged in your USB charging cable? If the answer is yes, then you might have found the problem.

Incompatible Attachment Solutions

The simple solution is to remove the attachment. This issue becomes more complicated when you have more than one attachment. You should remove all your attachments and plug them into your device one by one. This way, you will be able to determine which one is causing the problem.

Now that you know which attachment is causing the blinking lights, you can replace it. Your disposable vape pen won’t be compatible with every attachment on the market, so it is important to read the user manual that came with the device.

What if Your Disposable Vape Is Brand New and Blinking?

One of the most common questions that vapers ask us is, why is my disposable vape pen blinking when it is brand new?

An unlucky few vapers will get disposable vapes that are faulty. Every now and then, manufacturers will send out new electronic devices that have not been properly assembled. A blinking light can be a sign of an internal issue. In this case, a flashing light is the best thing that you can see. It is part of the internal safety system that alerts vapers to potentially harmful faults.

All sorts of things could be going on inside your disposable vape. One of the biggest reasons why new vape pens start blinking is air pressure. Some pens travel thousands of miles to your doorstep or local vape store. Along the way, they are subject to massive variations in air pressure. This causes the pods or tanks to leak. Even the most gentle air pressure can have an impact.

Blinking New Device Solutions

You might be tempted to disassemble your disposable vape to try to identify the issue. Any attempts to solve the issue should be left to the manufacturer, which is better equipped to handle any electronic faults, technical issues, and dangerous situations.

The best solution is to send your disposable vape back. You can do this in a few different ways. If you purchased the device online, just take a video or picture of the problem and send them to the manufacturer in an email. If you purchased your disposable vape from a shop, repackage it and return it along with your receipt.

Summing Up

There you have it! Low battery, low e-liquid, puff timer limits, incompatible attachments, and internal damage could all be the cause of your blinking light, but we’d say that it’s very unlucky to have all four. To solve your blinking disposable vape dilemma, start with the easiest solution.

Vape maintenance might seem daunting, especially for people who think they’ve hit the jackpot with a simple disposable vape device. Vaping is a journey, and as you become more experienced you will build up a wealth of valuable knowledge. In a few months’ time, you’ll know these answers and solutions off the top of your head.
