Is it better to use PG or VG for vape coil

Choosing between PG and VG for vape coils depends on personal preference; PG offers better flavor and coil longevity, while VG provides denser vapor clouds.

Understanding Vape Coils and E-Liquids

Vape coils and e-liquids are the heart of vaping experience. Each component plays a critical role in delivering satisfying vapor.

Composition of Vape Coils

Vape coils, typically made from materials like kanthal, nickel, or stainless steel, are the heating elements in e-cigarettes. They heat the e-liquid to create vapor. The resistance of these coils, measured in ohms, significantly influences the vaping experience. Lower resistance coils generate more heat and vapor, but consume more battery power and e-liquid. For instance, a 0.5-ohm coil, common in sub-ohm vaping, can produce dense vapor but might require frequent battery recharging.

Overview of E-Liquid Ingredients

E-liquids consist mainly of Propylene Glycol (PG), Vegetable Glycerin (VG), flavorings, and nicotine. PG carries flavor better and offers a stronger throat hit, mimicking traditional smoking. VG, on the other hand, is thicker, creating denser vapor clouds. The PG/VG ratio determines the liquid’s thickness, taste, and vapor production. A typical ratio is 70% VG to 30% PG, balancing flavor and cloud production. Quality of ingredients is crucial; premium e-liquids often boast higher purity levels, enhancing the overall vaping experience.

E-liquids come in various nicotine strengths, catering to different preferences and needs. For example, a high nicotine content e-liquid might contain 18 mg/ml, suitable for heavy smokers transitioning to vaping, whereas a 3 mg/ml concentration might appeal to casual vapers. The choice of nicotine strength impacts both the throat hit and the overall satisfaction derived from vaping.

Both vape coils and e-liquids have evolved significantly, with advancements aimed at improving longevity, flavor, and vapor production. For instance, mesh coils have become popular for their even heat distribution and longer lifespan, often lasting several weeks before needing replacement. Similarly, advancements in e-liquid formulations have led to a wider variety of flavors and more balanced PG/VG ratios, catering to a broader range of vaping preferences.

In conclusion, understanding the composition and characteristics of vape coils and e-liquids is essential for a fulfilling vaping experience. From coil material and resistance to e-liquid ingredients and nicotine strength, each aspect plays a pivotal role in shaping the quality of vapor, flavor, and overall satisfaction.

Properties of PG (Propylene Glycol) in Vaping

Propylene Glycol (PG) is a key ingredient in e-liquids, known for its thin viscosity and ability to carry flavors effectively in vaping.

Impact of PG on Throat Hit and Flavor

PG is renowned for providing a stronger throat hit, akin to the sensation of smoking traditional cigarettes. This feature makes it popular among former smokers who switch to vaping. PG is a flavor carrier; it enhances the e-liquid’s taste, allowing for a more pronounced and crisp flavor profile. In e-liquids with a higher PG ratio, flavors like mint or citrus are more vivid and distinct, providing a more intense sensory experience.

PG’s Effect on Vape Coil Lifespan

Due to its thin consistency, PG-based e-liquids are less likely to cause coil gunk, a common issue with VG-heavy liquids. This property of PG helps in prolonging the lifespan of vape coils. Coils used with high PG liquids often last longer, reducing the frequency of replacements and maintenance costs. For example, a coil used with a PG-dominated e-liquid might last several weeks longer than one used with a high VG liquid, leading to less frequent coil changes and a more cost-effective vaping experience.


PG’s lower viscosity also means it works well with smaller, less powerful devices, which are often more economical. These devices, with coils designed for higher resistance, are less strained by PG’s thin nature, thereby enhancing their durability and efficiency.

In summary, PG’s properties make it a preferred choice for vapers seeking a strong throat hit and clear flavors. Its compatibility with various devices and positive impact on coil longevity add to its appeal, making it a staple ingredient in the vaping world.

Characteristics of VG (Vegetable Glycerin) in Vaping

Vegetable Glycerin (VG) is a key component in e-liquids, known for its distinct properties that shape the vaping experience.

VG’s Influence on Vapor Production

VG stands out in the vaping world for its ability to produce large, dense vapor clouds. This characteristic is a major draw for cloud chasers and those who prefer a visually impressive vaping experience. The thick nature of VG aids in creating voluminous vapor, which is significantly more pronounced than that produced by PG-based liquids. For instance, an e-liquid with a high VG content, like a 70% VG blend, is capable of producing much larger vapor clouds compared to a 70% PG blend. This makes VG a favorite among those who prioritize cloud production over throat hit.

Effects of VG on Coil Gunking and Maintenance

However, VG’s thickness has a downside: it tends to gunk up vape coils faster than PG. This gunking can reduce coil lifespan and necessitate more frequent cleaning and replacement. For example, a coil used with a VG-heavy e-liquid might need replacing or cleaning every few weeks, compared to a longer interval for a PG-based liquid. This means higher maintenance requirements and potentially increased costs for vapers using VG-dominant e-liquids. Despite this, many vapers find the trade-off acceptable for the enhanced vapor production and smoother throat hit that VG provides.

In summary, VG’s role in vaping is defined by its ability to generate substantial vapor clouds and its smoother hit, offering a different sensory experience compared to PG. These benefits come with the need for more frequent maintenance of vaping hardware due to VG’s viscosity. For vapers who prioritize cloud production and a smoother inhale, VG remains a popular choice, despite the higher maintenance demands.

Comparative Analysis

Coil Compatibility with PG and VG

PG’s thin viscosity makes it compatible with a wide range of coils, especially those in smaller, less powerful vaping devices. Its lower density allows for easy wicking, ensuring efficient vaporization without overstraining the coil. VG, with its thicker consistency, is better suited for larger, more powerful devices with sub-ohm coils. These devices can handle VG’s density, enabling them to produce the large vapor clouds that VG is known for. However, VG can pose a challenge for smaller coils, leading to slower wicking and potential dry hits.

Longevity and Performance

When it comes to coil longevity and performance, PG and VG have distinct impacts. PG’s thinness means less residue buildup, translating to longer coil life and consistent performance. In contrast, VG’s thickness can lead to faster gunk accumulation, necessitating more frequent coil cleaning or replacement. For example, a coil used with a high VG liquid might last a few weeks, whereas a coil used with a high PG liquid can last several weeks or more, depending on usage patterns.

Below is a comparative table highlighting key aspects of PG vs. VG:

Aspect PG (Propylene Glycol) VG (Vegetable Glycerin)
Coil Compatibility High (especially with smaller, low-wattage devices) Moderate (better with larger, sub-ohm devices)
