Five Possible Reasons that Your Vape Pen is Blinking

Five Possible Reasons that Your Vape Pen is Blinking

Here are five potential causes for blinking disposable vape devices:

1. Low Battery Warning

A low battery warning means the battery is drained and needs recharging. But, if you’ve recently charged your refillable or disposable vape pen but still have no vapour upon inhaling, it might be due to an empty e-juice.

2. Overheating Alert

Receive an overheating alert if your disposable vape pen gets too hot. Also, if your vape starts to look bigger than usual, it could signal a battery problem.

3. Connection Issues

This might happen if the cartridge isn’t properly screwed onto the battery or debris interferes with the connection. Ensuring a flawless refill experience involves mastering the process of opening a vape pen cartridge and confidently reconnecting it to avoid any potential issues.

4. Short Circuit Protection

A short circuit in the device could be indicated by the blinking light.

5. Puff Activation Timer

Disposable vape pens often have a built-in timer that limits the length of each puff to prevent overheating and conserve battery life. If you inhale for too long, the pen may blink to signal that it’s reached its puff duration limit.

Five Tips to Fix Disposable Vape Pen Blinking

Five Tips to Fix Disposable Vape Pen Blinking

Here are five tips to fix your blinking vape pen:

1. Charge the Battery

If your disposable vape is blinking and not producing vapour, it might be due to a depleted battery. Plug it into a charger and ensure it gets a full charge. Weak lithium ion batteries can sometimes cause the device to blink as a warning sign.

2. Try Different Puffs

In some cases, rapid blinking occurs when the vape detects unusually sallow or shorter puffs. Try taking longer, more deliberate draws to see if this resolves the blinking. The device might be designed to activate only with certain puff patterns.

Never chain vape; always allow your device to settle for several seconds between breaths. If the battery is overheated, its charge will deplete more rapidly. It is also not healthy for your throat.

3. Troubleshooting the Battery Connection

Adjust the battery to ensure it’s properly seated in the device. Sometimes, a loose connection can cause the blinking issue, so make sure everything is snugly in place. Here are more troubleshooting tips: Vape Pen Troubleshooting

4. Restart the Device

Try turning the device off (if it has a power button) and then back on. This simple reboot can sometimes resolve the issue.

5. Temperature Matters

Extreme temperatures can affect the performance of disposable vapes. It is critical to avoid leaving your vape battery out in the heat and to avoid excessive exposure to direct sunlight. If you’ve left your vape in a very cold or hot environment, let it reach room temperature before using it. It can help prevent blinking caused by temperature-related issues.

The three flashes could indicate a battery or connection problem. The blinking light sometimes signals a low vape battery or a disconnection between the battery and vape cartridge. Quickly peek into your device’s user manual for a clearer picture of the issue. Don’t let the blinking lights get you down โ€“ it might be a minor bump on your vaping journey!

The most likely reason is a short-circuited coil or a coil with a resistance value that’s too small. A short circuit happens when the wires in the coil touch where they shouldn’t, causing the pen’s safety mechanism to kick in and make it blink. Likewise, a coil with low resistance strains the pen’s parts, triggering blinking.

The reason is a dead battery. Plug it in and let it charge. Depending on the size of the battery, this could take one or two hours. Revive your vape pen with a quick charge.

It is a helpful reminder that your supply of vape juice might be running low. Vape pens usually come pre-filled with around 300 puffs’ worth of vaping liquid, typically 1 ml in volume. The pulsating blue LED indicates it’s time to refill your vape juice after finishing all your puffs.
