Your vape tastes burnt most often because the coil or wick inside the device is overheating or burning. This burnt taste usually happens when the wick—the cotton material that absorbs the e-liquid—dries out or scorches. Common reasons for this include:

• Not priming a new coil properly by letting the wick soak with e-liquid before using it.
• Running low on e-liquid, so the wick is no longer saturated.
• Vaping at too high a wattage which overheats the coil faster than the wick can keep up.
• Chain vaping, where multiple hits are taken in quick succession and the wick doesn’t have time to absorb liquid.
• Residue buildup on the coil from sweeteners in the e-liquid causing a burnt or caramelized flavor.

To fix this:

• Make sure to prime new coils by soaking the cotton before vaping.
• Keep your tank or pod topped up with e-liquid and never let it run near empty.
• Check and lower your wattage to the recommended range for your coil.
• Avoid chain vaping to let the wick saturate between puffs.
• Replace the coil if the burnt taste persists after these steps.

Following these measures can prevent a burnt taste and ensure your vape stays flavorful and smooth.
