A burnt flavor can be attributed to a number of different variables, so it's important to be aware of everything that can effect your vaping experience. Here are a few of the most common issues that our customers face when it comes to burnt out coils:
1. Too high of a voltage/wattage. If using a VV/VW battery, try dialing down the voltage/wattage until a more desirable result is achieved.
2. If not using a VV/VW battery, make sure that the resistance on the coil is high enough for the battery to output properly. A lower resistance coil will fire hotter and may contribute to a burnt flavor.
3. The coil in the clearomizer/tank may be burnt out. Coils are a disposable portion of the e-cigarette and have an average life of 1-2 weeks. This lifespan may be longer, or shorter, depending on vape habits. Replacing the coil should alleviate a burnt flavor.
4. Ensure that you're priming your coils properly. If the cotton of the atomizer is not properly soaked through, it can lead to dry hits and a terrible burnt taste. In order to properly prime the coil, ensure that you are giving the coil enough time to soak in the e-liquid; about 30 minutes to an hour should do the trick if you're just letting it sit in the tank. Otherwise, you can also drip e-liquid directly onto the coil itself, if you don't want to wait.
5. Dark or sweet eliquids. Eliquids that are very dark in color, or are very sweet, have a tendency to produce a "gunk" like substance around the coil. This gunk can clog your atomizer which makes it so the wick cannot properly saturate. Wiping the gunk off the surface of the coil with a q-tip will temporarily alleviate a burnt taste caused by dark or sweet eliquids. You may also rinse the coil with hot water and let it air dry overnight. Generally, coils that are used with dark or sweet eliquids will not last as long and will need to be changed more often.
