Vape coils come in a diverse range, with variations in resistance levels, materials, wire types, and wicking materials. The choice of coil impacts the types of E-Liquids you can use, the wattage for vaping, and the required vaping technique. This choice is crucial for your vaping experience.
Each vape kit is designed to work with specific coils. For beginners, the range of compatible coils might seem limited. It’s important to refer to the product description or the user manual of your vape kit to select the right coil for your device and E-Liquid.
Differentiating Coils by Resistance
Coil resistance, measured in ohms (Ω), indicates how much electricity the coil can conduct from the battery. In simple terms, higher power output corresponds to lower coil resistance, and vice versa. This implies:
- Devices with high wattage need coils with low resistance (below 1 ohm).
- Devices with low wattage work best with high-resistance coils (above 1 ohm).
Both low and high resistance coils serve specific purposes and are compatible with certain types of E-Liquids and vaping styles.
MTL Coils (Above 1 ohm)
Mouth-to-Lung (MTL) coils, with higher resistance, are designed for MTL vaping. They work well with E-Liquids high in propylene glycol (PG), including nicotine salts and 50/50 freebase E-Liquids.
These coils produce less vapor and offer a draw similar to traditional cigarettes, ideal for MTL vapers. They also allow for a cooler vape and a smoother experience with high-nicotine E-Liquids.
MTL coils are commonly found in starter kits, pod kits, and MTL tanks.
DTL/Sub-Ohm Coils (Below 1 ohm)
Sub-ohm or Direct-to-Lung (DTL) coils have lower resistance, conducting more power. They are suited for E-Liquids with a higher vegetable glycerin (VG) content, like shortfills and 100% VG E-Liquids.
Used in sub-ohm tanks and advanced vape kits, these coils are favored by vapers who enjoy intense flavor and large vapor clouds. However, they tend to use more battery power and E-Liquid.
Coil Wire Types
Vape coils are primarily categorized into wire and mesh types, each offering unique benefits. The wire connects the positive and negative parts of the battery within the coil.
Wire coils, typically spiral-shaped, are a common choice, especially for sub-ohm vaping. They come in single, dual, or quad coil configurations but all feature the same spiral design.
Mesh coils, made from a net-like material, have a larger surface area, allowing for quicker heating and more vapor production than wire coils. They are increasingly popular, especially in MTL devices, but consume more E-Liquid and battery power.
Coil Material Types
Coils are made from various materials, with stainless steel being a standard choice. Other materials include titanium, Kanthal, nickel, and nichrome, each offering different properties in vapor production, temperature control, and heat generation.
For example, stainless steel is versatile for both wattage and temperature control modes, while Kanthal is suitable only for wattage mode, and nickel is best for temperature control.
Wicking Material Varieties
Common wicking materials in coils are cotton and ceramic, with other options like rayon and silica available for those who build their own coils.
Cotton, the most prevalent wicking material, offers a good balance of absorption, durability, and flavor. It’s the standard in most vape kits.
Ceramic coils, known for their longevity and absorbency, differ as they don’t use a traditional wick. Instead, the wire is coated in ceramic. They provide an even flavor and last longer than cotton, but consume more E-Liquid.
How Do Vape Coils Work?
Vape coils are integral to the operation of electronic cigarettes and vaping devices, transforming electrical energy into heat to vaporize e-liquid. Here’s a step-by-step explanation of this process:
1. Absorption of E-Liquid
The coil’s wicking material, usually cotton, soaks up the e-liquid from the device’s tank. This step is crucial as it prepares the liquid for heating and vaporization.
2. Activation and Electrical Current
Upon activating the device (through a button or an automatic draw-activated mechanism), an electrical current flows from the battery to the coil.
3. Heating Process
The coil, made of a resistive material like Kanthal or stainless steel, heats up due to the electrical resistance it offers. The amount of heat generated depends on the coil’s resistance level, measured in ohms. Lower resistance coils heat up more and faster, producing more vapor, while higher resistance coils generate less heat.
4. Vaporization of E-Liquid
The heat from the coil causes the absorbed e-liquid to vaporize. This vapor, containing the e-liquid’s flavors and nicotine, is inhaled by the user.
5. Cooling Down
After deactivation, the electrical current stops, and the coil cools down, ending the vaporization process.
6. Preparation for Next Use
The wicking material then reabsorbs e-liquid from the tank, readying the coil for subsequent use.
In the working of vape coils, several factors play a crucial role in influencing their performance. The resistance of the coil is paramount; it determines the heating dynamics, directly impacting the amount and intensity of vapor produced as well as the flavor. The type of wicking material used, typically cotton, also significantly affects the process, as it dictates the efficiency with which the e-liquid is absorbed and then vaporized. Additionally, the composition of the e-liquid, particularly the ratio of propylene glycol (PG) to vegetable glycerin (VG), influences the optimal heating temperature, which in turn guides the choice of the coil. These elements collectively shape the vaping experience, making their consideration essential for any vaper.
How to Choose the Right Vape Coil?
When venturing into the world of vaping, selecting the right vape coil is a crucial step that can greatly enhance your experience. Understanding and balancing several factors is key to making an informed choice.
The resistance level of the coil, measured in ohms, is a critical aspect to consider. Lower resistance coils, known as sub-ohm, are preferred for their ability to heat up quickly and produce substantial vapor, making them ideal for vapers who enjoy direct-to-lung inhalation and intense flavors. On the other hand, higher resistance coils offer a more controlled experience, akin to traditional cigarette smoking, and are well-suited for mouth-to-lung vaping.
The material of the coil also plays a significant role. Different materials like Kanthal, stainless steel, nickel, and titanium each bring unique characteristics to the vaping experience, influencing aspects such as flavor, vapor production, and compatibility with temperature control features. For instance, stainless steel is versatile for both wattage and temperature control modes, while Kanthal is renowned for its durability in wattage mode.
