Not only does it ruin your vaping experience, but it can also indicate an issue with your device that could reduce its lifespan.
Vaporesso users often choose the brand for its consistent flavour output, so getting a burnt taste from a Vaporesso device is not only disappointing, but also a clear signal that something is amiss. In this article, we’ll explore the specific reasons why your Vaporesso might taste burnt and provide solutions to get you back to enjoying smooth, flavourful clouds.
Before we get into the causes and their solutions, it's important to understand what causes that unpleasant burnt taste. It occurs when the wick inside the coil is not sufficiently saturated with e-liquid, causing the cotton to scorch instead of vaporising the liquid. As we’ll see below, this can happen due to various reasons, including incorrect wattage settings, coil degradation, or even using the wrong type of e-liquid.
1. Low E-Liquid Levels
Maintaining sufficient e-liquid is vital for all vapes, as low levels lead to dry hits. Vaporesso devices are no exception. Whether it's a pod or a high-powered tank, the wick must remain saturated. If e-liquid drops below the wicking ports, the wick can't properly absorb liquid, leading to a burnt taste. Regularly topping up your tank or pod will, of course, prevent this issue.
2. Too High Wattage
Vaporesso devices, with their advanced chipsets like the AXON chip, offer precise wattage control, but it is essential to understand that Vaporesso's coils, like all vape coils, have specific wattage ranges for optimal vaporisation. These ranges, clearly marked on the coil or its packaging, are crucial for preventing burnt hits, as exceeding them overheats the coil, rapidly dries the wick, and causes a burnt taste.
When purchasing new coils, always double-check the recommended wattage range before vaping.
For example, Vaporesso’s popular GTX coils have these ranges:
These ranges are where the coils perform best, but using a wattage above the coil’s rating, like 70W with the 0.2Ω coil, will likely result in a burnt hit.
Vaporesso's Smart Mode, found on many of their devices, can automatically set the appropriate wattage, which is particularly helpful for beginners. However, it's not foolproof, and sometimes, especially with older coils or those with minor resistance variations, it might miscalculate. Considering this, always double-check the recommended wattage on the coil itself.
3. Improper Priming
Building on our understanding of how a burnt taste occurs — when the wick scorches due to lack of e-liquid — improper priming is a direct cause. New coils, containing a cotton wick, must be fully saturated before firing to prevent this. Skipping this step leads to instant scorching and a ruined coil, a common issue across all vape devices, not just those by Vaporesso.
To properly prime your Vaporesso coils:
Correct priming prevents wick scorching, ensuring optimal flavour and coil longevity in your Vaporesso device.
4. Chain Vaping
Taking multiple puffs in rapid succession (otherwise known as chain vaping) is a common habit among vapers, but it can lead to significant problems, especially with high-powered devices. When you chain vape, the wick doesn't get enough time to re-saturate between puffs.
Vaporesso devices are known for their fast firing speeds and powerful output. While this provides an excellent vaping experience, it also means they can quickly overheat if used excessively.
To avoid burnt hits from chain vaping:
5. Worn Out Coils
Like any consumable component, vape coils have a limited lifespan, as over time, the constant heating and vaporisation process degrades the coil and wick. This leads to performance decline and eventually a persistent burnt taste, even with proper e-liquid levels and wattage settings. This inevitable wear affects all coils, Vaporesso's included.
Signs of a worn-out coil include:
Be sure to replace your Vaporesso coil as soon as you notice these signs to avoid a poor experience and potential device damage.
6. Incorrect E-Liquid Type
The type of e-liquid you use plays a crucial role in your coil’s longevity, and matching your e-liquid VG/PG ratio to your coil is key to avoiding burnt coils. Using e-liquid that's too thick (higher in VG) for a coil can cause poor wicking and burnt hits, while too thin (higher in PG) can lead to leaks.
Vaporesso coils are designed to be used with different e-liquids:
Using high VG e-liquids with MTL coils, or thin e-liquids with sub-ohm coils, will lead to problems, so always check compatibility to avoid getting that dreaded burnt taste.
7. Wrong Battery
For Vaporesso mods that use external batteries, using an incompatible or weak battery can result in inconsistent power delivery. This fluctuating voltage can result in coils either underheating, producing weak vapour and flavour, or overheating, leading to that unpleasant burnt taste.
Vaporesso mods are designed to operate within specific voltage and amperage ranges, and using batteries outside these parameters can lead to unpredictable behaviour. Always use recommended batteries that meet the voltage and amperage specifications for safe and reliable operation.
Most Vaporesso devices, like many modern vapes, feature adjustable airflow systems, allowing users to fine-tune their vaping experience, but an understanding of how airflow affects coil temperature is key to preventing burnt hits.
Vaporesso's sub-ohm tanks designed for DTL vaping require ample airflow to cool the high-powered coils. Conversely, MTL devices generally use more restricted airflow, but even these need adequate ventilation to prevent overheating. If your airflow is too restricted, you'll likely experience a burnt hit.
If you’re using a DTL device and a low resistance coil, chances are, you’re hoping to achieve a DTL inhale, so be sure to open the airflow!
Experiencing a burnt taste from your device can be frustrating, but as we've explored, it's often a preventable issue. By understanding the interplay between your device, coils, e-liquid, and vaping habits, you can significantly reduce the likelihood of encountering this unpleasant experience.
Vaporesso devices, with their advanced technology and wide-ranging coil options, are designed to deliver a premium vaping experience. However, like any precision instrument, they require proper care and attention. Pay close attention to your coil's specifications, e-liquid compatibility, and battery safety to ensure a smooth and enjoyable vape.
