My UWELL Nunchaku 2 Starter kit is not firing when I push the button

This is a surprisingly common issue that customers have and one of the easiest to solve. UWELL Nunchaku 2 kits are shipped in locked position.  This means that you need to unlock your vape by pushing the button 5 times quickly to unlock.  Once it is unlocked, it will blink to confirm it is unlocked and will work.

The other simple issue is that it is not charged.  Simply plug the unit into a charging area using a micro USB cord.  When the device is charging it will indicate with a light. When the charge is complete, the light will shut off.  This charging process typically takes 60-120 minutes.


My UWELL Nunchaku 2 is leaking

If your UWELL Nunchaku 2 is leaking there are a few things that you should be looked at in order to stop the leaking.  Because of the tank & coil design of the Joyetech UWELL Nunchaku 2 it is an unlikely device to leak but there are a few common issues that could cause it to leak.

A) Coil Missing or Misaligned:  If you don’t install a coil into your device, it will leak.  If the coil is screwed in incorrectly (miss-threaded) there is a possibility of a leak if the device is laid sideways.

B) Cracked glass:  If your UWELL Nunchaku 2 was dropped, or if it was in a pocket or purse that got bumped around a lot, it’s possible for the glass to have broken. Even if you do not see a crack, if the leak is coming from near the top, it is possible that the glass has been cracked. Glass can also crack in your UWELL Nunchaku 2 if it is left below freezing temperatures for a period of time. It is important to never leave your vape in a car that’s freezing.

C) Over Filling:  Overfilling your tank is the most likely reason for it to leak. There is a max fill line on your tank. Be sure to never fill your tank beyond the max fill line as it will leak out the top when you replace your coil.

When filling your UWELL Nunchaku 2 you do not need to remove the entire top along with the coil as you can simply unscrew the top most cap. Once you’ve unscrewed the top, you will see two kidney shaped filling holes. Watch as you are filling to ensure that you do not fill past the max fill line, and do not fill into the center hole.

D) Drawing Too Quickly:  If you take very fast, hard draws off just about any vaping device, including the UWELL Nunchaku 2, your device can be prone to leaking.  Vaping devices use the power of your inhale to pull e-liquid to the heating coils and mix with the vapour.  If you pull very long and hard on the device it is possible for some e-liquid to be pulled into the airflow chambers.  For all types of vaping, slow long drags are recommended.

E) Device Sitting For Too Long:  You should never store any vaping device filled with e-liquid.  Over time the e-liquid will saturate your coil and begin to leak.  If you are not planning on using your device for more then 24 hours be sure to empty all e-liquid.

F) Flying:  The increased pressure of flying will make all vaping products leak; even the UWELL Nunchaku 2.  It is best to empty all vaping devices before flying on a plane.

G) Over Heating:  If you leave any vape in a vehicle in the summer, especially in direct sunlight, it could leak.  Over heating the device can cause the e-liquid to expand pushing it out through the o-rings or through the airflow holes.

H) Freezing:  Leaving your device in a vehicle or any area under the freezing temperature could cause it to leak.  This is because some parts are plastic can become brittle and are then susceptible to breaking under freezing temperatures.  The ideal temperature for any vaping device is +10 to +25 degrees Celsius.
