A vape pen flashing four times is often a warning sign that the battery is completely drained or has reached a critically low level. In this case, it’s time to recharge your vape pen battery immediately to prevent further damage and ensure optimal performance.

(3) Vape Pen Flashing 5 Times

If your vape pen flashes five times, it could be an indication of a damaged battery or a more serious issue with the device. In this scenario, it’s recommended to stop using the vape pen immediately and consult the manufacturer or a professional for further assistance.

(4) Vape Pen Flashing 10 Times

A vape pen flashing ten times is a clear sign of a potential overheating issue. This could be caused by excessive use, a blocked airflow, or a problem with the device’s internal components. If this occurs, stop using the vape pen immediately and allow it to cool down before attempting to use it again.

(5) Vape Pen Blinking Blue

When your vape pen blinks blue, it typically indicates that the battery level is moderate. That’s usually between 30% and 70% capacity for most vape brands. This is a good reminder to keep an eye on your battery level and consider charging your device soon to prevent it from running out of power during your vaping session.

(6) Vape Pen Blinking Green

A vape pen blinking green is generally a positive sign, indicating that your battery is fully charged or has a high charge level, typically above 70% capacity. This means you can enjoy a longer vaping session without worrying about running out of battery power.

Common Reasons for Vape Pens Blinking Red

There are several potential reasons for this, and understanding them is key to resolving the issue.

#1 – Low Battery Level

When the battery level in your vape pen drops below a certain threshold, the device will typically start blinking red to alert you that it’s time to recharge. This low battery warning (low battery) is a common feature across most vaping devices, and it’s an important indicator to pay attention to.

Most vape pens will start blinking red when the battery capacity falls below 30% (medium battery power). While some devices may allow you to continue vaping until the battery is completely drained (dead battery), it’s generally recommended to recharge before reaching that point.

Repeatedly allowing your vape pen’s battery to drain completely can significantly reduce its overall lifespan and performance over time. Lithium-ion batteries, which are commonly used in vape pens, tend to degrade faster when subjected to frequent deep discharge cycles.

How to Fix Low Battery Power?

The solution to a low battery warning is straightforward: recharge your vape pen as soon as possible. It’s advisable to keep a spare battery or a portable charging case on hand, especially if you tend to have longer vaping sessions or are frequently on the go.

When recharging, make sure to use the charger specifically designed for your vape pen model. Using an incompatible charger can potentially damage the battery or cause other issues.

Be sure to follow the manufacturer’s recommended charging times and avoid leaving your vape pen plugged in for extended periods once it’s fully charged.

To prolong the overall lifespan of your vape pen’s battery, it’s best to develop a habit of recharging before it drops below 20-30% capacity. This practice will help minimize the stress on the battery and ensure a more consistent vaping experience.

#2 – Vape Pen Flashing Red When Charging

Contrary to popular belief, a blinking red light on your vape pen during charging is often a normal indication that the battery is charging correctly. Many devices use this red LED light as a visual cue to let you know that the charging process is underway.

When you first connect your vape pen to the charger, you may notice the indicator light blinking red (blink red, blinking red). This is simply the device’s way of confirming that it has established a proper connection and is actively charging the battery.

As the charging progresses, some devices may switch to a different colored light or a solid red light to indicate that the battery is reaching a higher charge level. Once the battery is fully charged, the light will typically turn green (green light) or turn off entirely.

How to Ensure your Vape Pen Keeps Charging Correctly?

There’s no need to “fix” this particular issue, as a blinking red light during charging is often a normal part of the device’s operation. However, it’s important to ensure that you’re using the correct charger and following the manufacturer’s recommended charging procedures.

Using an incompatible charger or one with the wrong voltage/amperage rating can potentially cause problems, such as overcharging or damaging the battery. Always use the charger that came with your vape pen or one specifically designed for that model.

It’s also a good practice to unplug your vape pen from the charger once it’s fully charged (full battery). Leaving it connected for extended periods after reaching a full charge can potentially overcharge the battery and reduce its lifespan.

#3 – Vape Pen Battery Overheating

While vape pens are designed to be portable and convenient, excessive use or improper charging can sometimes cause the battery to overheat. When this happens, many devices will start blinking red (blinks red) as a warning sign to prevent further overheating and potential safety hazards. The best cannabis vape batteries have auto shutoff feature to prevent excessive overheating.

Overheating can occur for several reasons, such as extended vaping sessions without breaks, using the device in direct sunlight or high temperatures, or leaving it connected to the charger for too long after reaching a full charge.
