Pro Tips for Lasting Vaping Sessions with Caliburn G4 Mini Pod Kit
Use the Right E-Liquid
Stick to nic salts or 50/50 VG/PG e-liquids for smoother hits and longer coil life.
Let the Coil Soak Properly
After filling the pod, wait 5–10 minutes before vaping. This prevents dry hits and a burnt taste.
Avoid Chain Vaping
Give the coil a few seconds between puffs to stay saturated and cool, which helps it last longer.
Keep the Pod Filled
Don’t let the e-liquid level get too low. Refill when it’s about 1/4 full to avoid burning the coil.
Clean the Pod Contacts
Wipe the pod and device contacts regularly with a dry tissue to ensure a strong, clean connection.
Store Upright
Keep your device standing upright to prevent leaks and keep the wick evenly saturated.
Inhale Gently
The G4 Mini is draw-activated, so soft, slow inhales work best and reduce stress on the coil.
Monitor Battery Level
Charge before it gets too low. A full battery ensures consistent output and flavour.
Use Original Pods
Stick with official Caliburn G4 pods for the best performance and longevity.
Don’t Overcharge
Unplug the device once fully charged to preserve battery health over time.
