Troubleshooting Guide
The Innokin T20S troubleshooting guide helps solve common issues such as charging problems, weak vapour, leaking, or coil-related problems.
Innokin T20S Battery Not Charging
If your device is not charging, check the USB cable and power source first. Try another compatible cable and inspect the charging port for dirt or damage. If the LED does not respond, the battery may need inspection.
Innokin T20S Blinking Light Meaning
A blinking LED usually shows a battery warning or device protection feature. Charge the device and check that the tank and coil are fitted correctly before trying again.
Innokin T20S Leaking Solution
Leaks can happen when the tank is overfilled, the coil is not installed correctly, or seals are damaged. Remove excess liquid, tighten the tank parts, and replace damaged seals if required.
Weak Flavour Or Low Vapour Output
If flavour becomes weaker, check the battery level and e-liquid amount. A worn coil can reduce flavour and vapour, so replacing the Prism-S coil may solve the problem.
Burnt Taste From The Coil
A burnt taste usually means the coil is dry or has reached the end of its lifespan. Refill the tank, allow the coil to soak, or replace it with a new Prism-S coil.
Gurgling Sound During Use
Extra e-liquid inside the airflow tube can cause gurgling. Remove the tank, clean the mouthpiece area, and avoid overfilling the e-liquid reservoir.
Device Not Producing Vapour
Check that the device is switched on and the battery has enough charge. Make sure the coil is installed correctly and the tank has sufficient e-liquid.
Cleaning And Maintenance Tips
Regular cleaning helps maintain flavour and performance. Wipe the tank connection, clean the mouthpiece, remove old e-liquid residue, and replace coils when flavour quality decreases.
