Vape Pen Not Charging Green Light? (Causes & Fix)

Vape Pen Not Charging Green Light

Vape pens have skyrocketed in popularity over the last decade, providing an appealing alternative to smoking traditional cigarettes. However, as with any electronic device, vape pens can and do malfunction from time to time. One of the most commonly reported issues vape pen users face is the device not charging properly or the status light remaining green when it should turn blue or red during charging.

There are several potential root causes for a vape pen battery getting stuck on green even when plugged in. In this comprehensive troubleshooting guide, we’ll cover the main reasons a vape pen won’t charge past the green battery light and provide actionable tips to resolve the problem. With some basic maintenance and replacement of any malfunctioning parts, you can get your vape pen charging correctly again.

Vape Pen Light Meanings

Before we dive into troubleshooting, let’s review what the different colored indicator lights mean on a typical vape pen:

  • Green – Fully charged or ample charge remaining
  • Blue – Medium level charge
  • Red – Low battery/needs charging
  • Flashing Green – Actively charging
  • Solid Green – Finished charging

So if your vape pen status light is turning solid green but the battery is not actually charging fully, there is an underlying issue. Let’s explore why this happens and how to fix it.

What Causes the Green Light Charging Problem?

There are several possible explanations for why a vape pen won’t charge past the green battery light. Here are the most common culprits:

1. Faulty Battery

One of the most likely reasons a vape pen prematurely displays a full green charge is that the battery itself has degraded and can no longer accept a full charge. This is common with older batteries that have gone through hundreds of partial charge cycles. The chemicals inside lose capacity over time. Replacing the battery often resolves this green light charging issue.

2. Dirty or Damaged Charging Port

The charging port on a vape pen can become clogged with e-juice residue, pocket lint, and other debris over time which prevents a solid connection with the charger prongs. Carefully cleaning the port or replacing the part may be necessary if the contacts are damaged. Avoid using metal tools to clean the port.

3. Bad Power Source/Charger

Sometimes the green light problem is being caused by a bad USB cable, wall adapter, computer USB port, or external battery used to charge the vape pen. Test with multiple power sources to isolate the issue.

4. Moisture Damage Inside

E-liquid leaks or accidental water exposure can damage the interior electronics that control charging. Allowing the pen to fully dry out may help, but moisture causes corrosion which can permanently disrupt electrical connections.

5. Outdated Firmware Causing Software Bugs

For high-tech vape pens with internal processors, an outdated firmware version can introduce software bugs that affect charging. Download the latest firmware from the manufacturer and update the pen.

6. Defective Charging Port Electronics

In rare instances, the charging port assembly itself may be damaged or disconnected internally which would prevent full charging. This requires electronics repair or replacement.

7. Short Circuit in Battery Wiring

Damaged batteries can short circuit internally and fail to charge properly while still lighting up green. Inspect battery wiring for shorts if replacement batteries also exhibit rapid green light.

Step-by-Step Vape Pen Not Charging Green Light Troubleshooting Guide

With the main culprits in mind, follow these detailed troubleshooting steps to resolve your vape pen’s green light charging issue:

1. Try Different Chargers and Cables

First, try using alternative chargers, cables, wall adapters, battery packs, or USB ports to charge your vape pen. If the battery charges fully when using a different power source, then your original adapter or cable is likely defective.

2. Clean Out Charging Port

Inspect the charging port for any debris or e-juice residue that could impede a solid connection. Carefully use a toothpick, soft brush, or compressed air to remove any lint, dust, etc. Avoid metallic tools that could scratch contacts.

3. Update Firmware

Check the manufacturer’s website for any firmware updates for your vape pen model. Follow instructions carefully to install the latest firmware, as this can fix software bugs affecting charging.

4. Try a Fresh Battery

One foolproof way to test whether the issue stems from a bad battery is to install a brand new one. If the new battery charges fully past the green light, you can confirm the old battery was faulty.

5. Inspect Internal Electronics

Open up the vape pen casing carefully and check the charging port solder points, wires, and PCB for any signs of moisture corrosion or loose/severed connections. Repair any issues you find, or have an electronics technician handle.

6. Check Battery Voltage Levels

Use a voltmeter to check the battery voltage before and during charging. If voltage remains low and never increases despite the green light, the battery needs replacement.

7. Have Manufacturer Diagnose/Repair

For persistent green light problems even after trying the above remedies, contact the vape pen manufacturer for warranty service. Provide detailed information to aid their troubleshooting process.

8. Replace Defective Parts

Based on the diagnosis, replace any defective batteries, chargers, cables, charging port assemblies, or internal electronics components allowing the vape pen to charge fully again.

Preventing Future Charging Issues

Once resolved, you can take proactive steps to maximize your vape pen’s battery life and avoid further charging problems:

  • Avoid overcharging – don’t leave pens plugged in for extended periods after hitting green.
  • Let batteries cool off between charges rather than hot-charging back-to-back.
  • Keep charging ports clean/dry – store pens upright.
  • Use manufacturer approved wall adapters for charging rather than USB ports.
  • Consider an external battery charger for more control.
  • Charge to 40-50% capacity for long-term storage, not 100%.
  • Plan on replacing batteries at least every 12-18 months with heavy use.
  • Take batteries out of pens you won’t be using for a while to avoid deep discharge.

Following battery best practices will keep your vape pen charging smoothly for years to come!

FAQ

Why does my vape pen die so quickly after a full charge?

If your vape pen is dying prematurely even right after a full charge, the battery has likely lost charging capacity from repeated charging cycles and simply needs to be replaced.

Why won’t my vape pen power on after charging fully?

If a vape pen won’t turn on even after being plugged in for an extended period, there may be an issue with the battery itself or the internal logic board. Try replacing the battery first, then have electronics inspected if the problem persists.

Why won’t my vape pen produce vapor when the light is green?

With a fully charged battery indicated by a green light, the vape pen should activate and heat up when you take a draw. If not, there is likely a short circuit or wiring issue preventing proper current flow. Professional electronics repair may be required.

What are signs my battery needs replacing?

Common indicators your vape pen battery needs replacing include taking longer to charge, not holding a charge as long, no longer charging fully, and needing more frequent charging. Most vape pen batteries last 300-500 charge cycles.

Why does my vape pen get hot when charging?

Excessive heat during charging can signify a short circuit, damaged battery, or faulty charger. A thermal event prevents the battery from charging properly. Replace any defective components right away to avoid safety issues.

Conclusion

While a vape pen sticking on green when charging can be annoying, the problem is often easily resolved by cleaning ports, updating firmware, replacing batteries, or swapping chargers. With some diligent troubleshooting and maintenance, you can get your vape pen charging properly again and extend its useful lifespan. Always reach out to the manufacturer if problems persist after trying all standard fixes.
