The LED indicator gives you an idea of what is going on inside your vape pen. When your vape pen has a problem, the LED indicator will change colors, pulsate or blink. Not all vape pens are the same and it is important to understand what your light indicator means on your device.

While sometimes the reason behind the blinking is obvious such as low charge, improper installation, or connection problem, in some cases, the vape pen starts to blink for no good reason, which can be confusing.

What does it mean when a vape pen blinks? If you are asking this question, you should know that vape pens have different blinks that mean different things. Here are some of the common blinks that your vape pen can have and their meaning:

Vape pen blinks 3 times.

If your vape pen blinks multiple times, it could mean you have a connection problem between the battery and the heating oil.

The pen will also blink multiple times when you have a short circuit in the tank.

Sometimes the pen will blink three times without the tank. If this is happening to your pen, you might be having a battery problem.

If the LED blinks when connected to the tank, it might be due to a poor connection.

To fix the blinking problem, ensure that the heating oil and battery connection is clean and secure. If the blinking goes on, try using the battery with other coils/tanks to see if the problem is gone.

If the problem persists, you have to replace the coil/tank. If you do the replacement and there is still flickering, the problem is most likely with the vape pen battery.

Is your vape pen is still under warranty? Get in touch with the dealer for a replacement.

Vape pen blinks 4 times

Some pens will blink 4 or more times when the atomizer resistance is lower than 0.1 ohms or higher than 2.5 ohms.

Due to the lower resistance, the battery will automatically shut down the output to protect the pen. All you have to do is wait, then put the pen on again.

Vape pen blinks 5 times

In most cases, your vape pen will blink five-time or more times immediately after inhalation or usage, and it’s often a sign of a low battery.

To fix this issue, you need to charge your battery. You should note that even when you screw in your battery for charging, the LED will still blink, indicating that the charging process has begun.

Some high-end pens will blink five times as a warning that you are over vaping. When you press the fire button for a long time (over 10 seconds), the power output will shut off then the white light will flash 5 times.

This is meant to protect you from over vaping, and all you need to do is wait and vape again.

Of course, do it for less than 10 seconds this time around.

Why is my vape pen flashing 10 times?

The vape pen will sometimes blink 10 or more times due to plenty of reasons. The most common ones being:

Dying battery:  Most often, the vape pen will blink ten times when the battery is too low for proper vaping. To fix the issue, recharge the battery.

Low voltage: If the battery is charged but the pen is still blinking, it could be due to a low voltage. Low voltage often comes about due to poor battery connections, either due to dirt or improper lineup. To restore your pen to proper working condition, make the necessary adjustments.

Overextended hits: If you have a high-end vape pen, it will give you ten blinks to signify you are taking long hits. Most high-end vapes are designed to automatically shut off when you take too big hits, so if this is the case, you need to bring the pen back to life and take a smaller hit.

You need a new vape pen: How long have you had your vaping device? If you can’t remember when you got it, chances are it’s too old, and it’s time to get a new one.

Even the best quality devices aren’t designed to last forever, so if yours has been flashing and you have tried diagnosing it without success, chances are it has come to the end of its life, and it’s time to get a new one.

Vape pen blinking red

Some of your devices will blink red under different situations, and each situation has a different meaning. If the pen blinks red when vaping, it’s a sign your battery is going low (below 30%), and it’s time to recharge it.

On the other hand, if the red or another color blinking happens when charging the pen, it simply means that the charging is happening.

When you press the power button 3 times, and the indicator light blinks red, it means that the vape pen has switched to low mode power output.

Vape pen blinking blue

If the blue blinking happens when you are vaping, it could be a  sign you have medium battery power (at least 30%).

Does the blue blinking come after pressing the power button 3 times? It means that the vape pen has switched to medium mode power output.

Vape pen blinking green

When you are vaping, and the pen blinks green, it could mean you have full or near full battery power (at least 70%).

If you have connected the pen to power for charging, then the green light comes on, which means that the charging has been completed.

When you press the power button 3 times, and the green blinking happens, it indicates that the vape pen has switched to high mode power output.

Why won’t my vape pen hit?

Sometimes you will have the vape pen fully charged, with enough cannabis material, and no blinking lights, but still, it won’t hit. This can be brought about by a variety of factors, with the most common ones being:

The battery is off: Sometimes, you will have a full battery, but if you don’t turn it on, you won’t get the hit you are looking for. Depending on your vaping device, you may need to press the firing button five times to bring it to life.

When the device comes on, check the indicating lights. If the battery is full, you should have green lights, but if they are red or orange, you may have to recharge them or replace them with a fresh set.

Firing pin sitting too low: The firing pin is designed to move up and down to connect with the clearomizer and give you a solid electrical current to the coils.

Sometimes due to excessive use or abuse, the pin will get too far down into the connector, and it fails to make a connection hence the reason you aren’t getting a hit even when everything else seems to be working properly.

To fix this problem, remove your clearomizer from the top and look inside the connector. If the firing pin is sitting too low, use a screwdriver and gently wiggle it loose until it springs back up.

Flooded coil and atomizer: If your tank is full, but you aren’t getting any vapor, or the vapor is too low, it could be due to a flooded atomizer or coil. To fix this, take your atomizer apart and clean it using a paper towel. You can alternatively blow through it to remove the excess liquid.

While at it, look at the firing pin and connector. If the liquid has leaked out of these areas, clean them with a bit of paper towel or cotton swab to ensure a solid connection.

You are using a low-powered device: If everything checks out, but still you won’t get a hit, it could be because the device is too weak. If the device is still under warranty, you should return it to the dealer and get a better, more powerful vape pen that will give you the hit you are looking for.

What do the colors on a vape pen mean?

When the vape pen is on, it can give different lights that vary depending on the voltage setting. To change from one setting to the other, you need to click on the button twice.

Are you new to vape pens and are wondering what do the colors on a vape pen mean? Well, they have different meanings depending on the device:
Red: This is the highest voltage (4.0 volts). You get the biggest vape hit when you vape at this setting, but you often sacrifice the flavor. Some THC cartridges even begin to burn in this setting.
Blue: Also known as, the dab mode, the blue light will come on when you are vaping at 3.8 volts. You should only vape at this voltage when you are vaping extracts with a 510-thread wax atomizer. To avoid damage, only use cartridges that can take the setting.
Green: The green light will come on when you are vaping at a 3.6 volts setting. This is the best setting as it has been proven to prolong the battery life and, at the same time, reduce the heat used in vaporizing the contents in the cartridge.

Can you overcharge a vape pen?

Although you should keep the vape pen properly charged for a great vaping experience, you shouldn’t overcharge it.

Can you overcharge a vape pen? Yes, you can overcharge it when you leave it on the power for too long.

Depending on your vaping device, you will have white or red blinks signifying that it’s time to recharge the battery. Once your battery is full, the light on the screen will turn green, and you should disconnect your device from the power.

When you don’t remove the device from the power soon enough, you will damage it, and this can lead to plenty of problems such as:

Reduced battery life: When you leave the battery charging for too long, you have a constant energy charge circulating into the battery, which reduces the ability of the battery to hold a charge. You can recharge the battery for too long, so when you repeatedly overcharge it, it’s a matter of time before you degrade the battery’s capacity.

Increased charge leaks: Although most vaping battery chargers and batteries have protective mechanisms meant to stop the flow of charge when the battery is fully charged, there is always the risk of some high voltage charge leaking and filling the battery a little bit more.

As you can guess, the excess charge stretches out the battery, which significantly reduces the battery’s ability to hold a charge.

Overheating: When you continue adding more charge into an already full battery, you stress and strain it, which manifests itself in various ways, such as overheating and cracking.

There is also the risk of the battery exploding when you repeatedly overcharge it.

To avoid overcharging your vape pen’s battery, carefully monitor it when you connect it to a power source. As soon as the LED light turns green, remove the battery from the power source.

If you are fond of getting distracted when charging the battery, get yourself a high-end vape pen with built-in safety features to stop overcharging.

What is the best way to charge a vape pen battery?

For the best charging experience, charge the batteries at a moderate temperature (50-86 degrees F).

It’s common for the battery or device to get hot during the charging. When this happens, disconnect the device from the charger and wait for a few minutes, then reconnect it. If the device heats up again, you most likely have a battery or charger problem. Diagnose the problem to find the cause.

Keep a close eye on the vaping device and disconnect it from the power as soon as the green light comes on.

Never ignore any blinking lights.

Sometimes your vaping device will blink, then the lights go off, and it continues functioning normally. Other times, the device will blink and still function properly.

Even if it’s still working, you should not ignore the blinking as it might be a sign of a deeper underlying problem. Move with haste, find out the reason for the blinking, and fix it before it’s too late.
