There could be many reasons why your vape pen is blinking. But, the most common cause is a loose connection between the vape coil and battery. Although, they are many reasons why LED light indicates what is going on inside your vape system.

How Does a Vape Pen Work?

Well, I’ll not complicate things by explaining the principles of physics, but you should know the basic working process of an electronic cigarette.

A vaping device has many components but the main is- Battery, Coil, and E-Liquid.

The battery supplies the electric power to the coil, and vaping coil heat up. Due to generated heat, e-liquid inside the vape cartridge evaporates and creates clouds that we inhale into our lungs.

What if the connection of the battery is loose? It won’t pass the electric power, and the vape coil won’t heat up.

When you inhale, the sensor activates the vaping process, but the coil won’t get enough electricity from the battery.

As a result, your vape pen LED will blink to indicate the issue inside your vaping device.

Why is my Vape Pen Blinks 3 Times?

You understood the basic concept of vaping devices. Let’s see why your vape pen blinks 3 times when you press the button and inhale through the mouthpiece.

If your vape pen blinks 3 times, it indicates the loose connection with the battery. It also happens when a short circuit is detected in the tank or your vape coil is burnt.

You can disassemble your vape pen to check it and if the vape coil is burnt, you need to replace it. If you notice any sign of corrosion on battery terminals, you should clean them with a sharp knife or sandpaper.

Why is my Vape Pen Blinks 4 Times?

If you’re using Smok Vape Pen and it blinks 4 times; it means the resistance of the vape coil has been changed above 2.5 Ohm or resistance dropped below 0.1 Ohm.

Increased resistance of vape coil consumes more battery and it won’t last long. The microprocessor inside your vape detects an error and notifies you by blinking the LED light.

Why is my Vape Pen Blinks 10 Times?

If you haven’t charged your vape battery for long, then you’ll notice that your vape pen will blink 10 times or more when taking a puff.

If a vape pen blinks 10 times, it indicates low power output and it means your battery is dying. If your vape pen battery is rechargeable then you should plug in a charger or replace it.
