The Truth About Dry Hits: What Really Causes Them?

Each person who has used a vape knows the horror: the dreaded dry hit—that disgusting, burnt taste that ruins an otherwise silky vape experience. Low e-liquid levels are blamed, but there is more at play. Dry hits from a 2500 puff disposable vape can be caused by coil malfunctions, improper wicking, airflow adjustments, and even the e-liquid chemistry. Knowledge of the causes and prevention of dry hits can improve taste and prolong coil longevity.

What is a Dry Hit?

Dry hit is felt when the wick in the coil does not have enough e-liquid and therefore burns and overheats, leading to cotton or wicking material burning. Instead of vaporizing e-liquid, the coil burns dry cotton, which gives a harsh, bitter taste.

In contrast to regular vapor production, which produces full-flavored, rich clouds, dry hits produce:

• A burnt, acrid taste.
• An uncomfortably hot inhale.
• Inflammation of the lungs and throat.

The Most Commonly Experienced Dry Hits

Although dry hits might seem to be haphazard, they are often caused by one or more of the following:

1. Chain Vaping Without Re-Saturating the Wick

A couple of quick puffs are not giving the wick enough time to draw in more e-liquid. This, in turn, dries out the cotton over time, resulting in burnt hits.

How to fix it:

• Wait for several seconds between puffs so that the wick can absorb more e-liquid.
• When chain vaping is not avoidable, use a VG-richer e-liquid because it takes longer to vaporize.

2. Using Too High Wattage for Your Coil

Every coil has an optimal wattage range. It burns the wick faster than it can reabsorb e-liquid when exceeded. Excessive wattage produces too much heat, leading to premature burnout of coils.

How to Fix It:

• Keep the recommended wattage of your coil and stay in its range.
• If you own a variable wattage device, start at low wattage and work your way up.

3. Incorrect Wicking or Coil Saturation

With the installation of a completely new coil, faulty priming can cause immediate dry hits. Wick overload in rebuildable atomizers (RDAs and RTAs) restricts e-liquid flow as well as prevents saturation. Thankfully, a user of a 2500 puff disposable vape does not need to worry about these situations.

How to Repair It:

• Always pre-prime new coils by refilling the wick with e-liquid to be utilized.
• In rebuildable setups, place wicks in a way that e-liquid can flow freely.

4. Airflow Too Constricted or Too Free

Lack of airflow leads to overheating, and then rapid evaporation and dry hits. Too much air at high wattage can cause under-saturation.

How to Fix It:

• Control airflow to meet an equilibrium between vapor and wick saturation.
• Do not cut airflow off entirely unless employing a low-power, mouth-to-lung configuration.

5. Having the Wrong E-Liquid for Your Coil

High-VG e-liquids are thicker and take longer to prime coils, and that can cause dry hits with small coil devices like pod kits. High-PG e-liquids are leakier and more water-like but quicker-wicking in lower-wattage setups.

How to repair it:

• Use higher PG e-liquids (50/50 or 60/40) for pod systems and small coils.
• Use more potent VG e-liquids (70/30 or 80/20) in sub-ohm tanks and high-wattage setups.

Prevention of Dry Hits in the Future

To reduce dry hits and prolong coil life, use the following best practices:

• Always keep your e-liquid levels higher than the minimum line so that the wick will never dry out.
• Prime fresh coils on first use by hand soaking the wick.
• Modify wattage according to coil specifications in order to avoid early cotton burning.
• Make breaks between puffs to enable the wick to absorb e-liquid fully.
• Use the appropriate e-liquid VG/PG ratio for your device to produce saturation.

Endnote

Dry hits from a 2500 puff disposable vape can spoil a vaping session, but knowing what causes them makes it simpler to avoid them. Whether it is wattage settings, wicking problems, or airflow maladjustments, minor adjustments can enhance flavor, vapor output, and coil life. With the proper adjustments and vaping practices, you can have a smooth, consistent vaping experience without the dreaded burnt flavor.
