Vape Pen Not Charging Green Light? How To Fix It

After charging your vape pen in your bid to get set for a high time, discovering it isn’t functioning as expected doesn’t sit well. Your best bet is to be better prepared when next it does.

A vape pen not charging green light indicates a fault in the vape pen or dead vape pen batteries. To check if the vape pen is faulty, charge the vape pen with an external charger. If it charges, the vape pen charging port is defective, and you should fix it.

Generally, any issues with your vape pen will have to do with your pen itself or its charger. Read on to learn why a vape pen won’t charge and how to fix it.

Why Is My Vape Pen Blinking Green?

Your vape pen will blink green about 4 to 5 times if the connection linking the cartridge and battery is faulty. Leakages typically cause this in the cartridge, which breaks the connection. Also, using an irregular-sized cartridge or one with a deformed coil causes the vape to blink green. 

In the first case, you need to check and ensure that the coil fits tightly and its base is screwed correctly. If you’ve observed any leakages, a quick solution is to reach for a cotton swab and immerse it in rubbing alcohol. Swabbing the bottom of the cartridge and its connection point to the battery will address the situation. 

However, you will want to keep those dry before reconnecting them. If tightening and loosening the cartridge does not fix it, you will need to buy another cartridge. It is safest only to buy cartridges from licensed distributors to avoid this.

Why Is My Vape Flashing Green And Not Working?

If your vape is blinking green but not working, the vape battery is dead and needs to be recharged, or it’s permanently destroyed. When your vape pen battery is dead, it will normally flash green about 10 to 15 times. Connect it to power to charge and the vape will work. 

If your vape charger gives a red light, then your battery is dead. At full battery power, your vape charger will turn green, and your vape pen will indicate no light.

However, if none of this happens, it is an indication that your vape battery has died permanently, and to fix this, you will need a replacement.

How To Troubleshoot Vape Pen Not Charging Green Light

If you are experiencing problems with a vape pen battery that has refused to charge. Here is a DIY guide to help you put things in place:

  • Check to be sure if the vape is faulty
  • Test with external battery chargers
  • Replace your batteries

1. Check To Be Sure If Your Vape Is Faulty

A fault can cause a charging problem in the vape or its charger. You will need to find out where the problem lies before moving forward.

First, check your charging outlets (or sockets). Try your vape charger on another device if this isn’t at fault. If none of these shows any weakness, the problem can be from your vape.

2. Test With External Battery Chargers

Try out external chargers if you have them around and see if they work. If they do, then this can mean a port problem is imminent. If they don’t, your battery can be at fault.

3. Replace The Batteries

Get new batteries and try them on your vape. Then try charging them. If these two steps work out fine, your battery was at fault. Or else, the problem will have to be a connection problem.

4. Check The Connection Between Your Cartridge And The Battery

If your battery and cartridge aren’t correctly connected, your vape won’t work correctly, plus they won’t even charge.

5. Get A Soldering Iron

In rare situations, you will need a soldering iron. Some parts can shift noticeably, and you can put them back together with a soldering iron. However, this move is risky and can sabotage your vape. You sure want to tread carefully here.

6. Get A New Vape

If trying all that is above brings you to a dead end with no positive results, then what you dreaded has happened. It’s not too late, though. You can get a new vape at this point.
