When you pick up a sleek, discreet e‑cigarette and inhale, it can feel almost magical – a cloud of vapor appears, flavors burst on the palate, and nicotine is delivered without the ash and odor of a traditional cigarette. Behind that smooth experience lies a surprisingly intricate assembly of components, chemicals, and engineering decisions that make modern vaping possible. Understanding exactly what’s inside an e‑cigarette not only satisfies curiosity; it also empowers users to make safer choices, troubleshoot problems, and comply with regional regulations such as those enforced in Australia.
Below is a deep‑dive into the anatomy of a contemporary e‑cigarette, from the core power source to the minute flavor molecules that create the sensory experience. The discussion also highlights how premium brands like IGET and ALIBARBAR have refined each element to deliver longevity, consistency, and compliance with strict quality standards.
1. The Power Core – Lithium‑Ion Battery
1.1 Chemistry and Capacity
Most disposable and pod‑style devices rely on lithium‑ion (Li‑ion) batteries because of their high energy density, lightweight profile, and ability to deliver the rapid bursts of current required for vaporisation. Typical capacities range from 350 mAh in ultra‑compact disposables to 1500 mAh in larger, refillable mods. The voltage is usually set around 3.7 V (nominal) with a discharge voltage that can peak at 4.2 V when fully charged.
1.2 Safety Mechanisms
High‑grade e‑cig manufacturers incorporate several built‑in protections:
- Over‑charge protection (OCP) – Prevents the battery from exceeding 4.2 V, reducing the risk of venting or fire.
- Short‑circuit protection (SCP) – Instantly cuts current flow if the circuit is bridged unintentionally.
- Over‑discharge protection (ODP) – Stops the device once the voltage drops below a safe threshold (usually ~2.5 V), preserving battery lifespan.
IGET’s Bar Plus, for example, employs a self‑regulated battery module that automatically balances power output to preserve the 6000‑puff claim without user intervention.
2. The Atomiser Assembly – Where Heat Meets Liquid
2.1 Coil (Heating Element)
The coil is the heart of the vaporiser. Constructed from resistance‑rated metals such as Kanthal (FeCrAl), Nichrome (NiCr), Stainless Steel (SS), or Nickel (Ni200), the coil’s resistance determines how much power it draws and thus the temperature it reaches. Typical resistance values:
- Sub‑Ohm (≤ 0.8 Ω) – Used in high‑power devices for large clouds.
- Standard (1.0‑2.0 Ω) – Balanced flavour and vapour production for most pod devices.
- High‑Resistance (≥ 2.0 Ω) – Ideal for low‑power, mouth‑to‑lung (MTL) vaping with tighter draws.
Coil geometry (single, dual, mesh) also influences heat distribution. Mesh coils provide a larger surface area, delivering evaporative efficiency and a smoother flavour profile, a design frequently found in ALIBARBAR’s premium disposables.
2.2 Wick (Capillary Action)
Capillary wicking transports e‑liquid from the reservoir to the coil. Common wick materials include:
- Silica‑based cotton – Highly absorbent, offering consistent saturation.
- Ceramic – Offers superior thermal stability and longer life.
- Stainless‑steel mesh – Used in some drip‑tips for rapid liquid delivery.
Manufacturers often pre‑soak the wick during assembly to avoid dry‑hits out of the box. A well‑engineered wick prevents overheating, which can otherwise generate acrolein, a potentially irritating aldehyde.
2.3 Chipset (Power Regulation)
Beyond the battery, a modest printed circuit board (PCB) moderates voltage and current. In disposable devices, this is a “fixed‑output” chipset calibrated at the factory to deliver a set wattage (e.g., 5 W, 7 W, 10 W). In refillable mods, the chipset includes variable wattage, temperature control, and safety cut‑offs.
Key features:
- Ohm’s Law calculators – Allow the device to automatically adjust voltage based on coil resistance.
- Temperature sensors – Thermistors or RTDs monitor coil heat to prevent overheating.
- Airflow sensors – Detect draw pressure to trigger vapor production only when the user inhales.
3. The Liquid Reservoir – E‑Liquid Composition
3.1 Base Solvents
| Component | Typical Ratio | Function |
|---|---|---|
| Propylene Glycol (PG) | 30‑70 % | Thinner viscosity, carries flavour, provides “throat hit”. |
| Vegetable Glycerin (VG) | 30‑70 % | Thicker, creates dense vapor, smoother on the throat. |
High‑VG blends (≥ 70 % VG) are popular for cloud‑chasing, while high‑PG formulas (≥ 70 % PG) deliver stronger flavour and a tighter draw reminiscent of cigarettes. Many disposable products, such as IGET’s Bar Plus, use a balanced 50/50 PG/VG ratio to achieve a compromise between flavour fidelity and vapor volume.
3.2 Nicotine
Nicotine can be present in free‑base form or as a nicotine salt. Salt nicotine, created by combining nicotine with an acid (commonly benzoic acid), lowers the pH and reduces harshness, enabling higher nicotine concentrations (e.g., 20 mg/mL) without an uncomfortable throat hit.
Australian regulations cap nicotine concentration in e‑liquids sold domestically at 20 mg/mL, a limit that both IGET and ALIBARBAR strictly respect in their product lines.
3.3 Flavour Constituents
Natural and artificial flavourings contribute the sensory palette. Industry‑standard flavour houses such as Givaudan and Firmenich supply food‑grade terpenes, esters, and aldehydes that are Generally Recognized As Safe (GRAS) when ingested. Inhalation safety is a separate consideration; reputable manufacturers conduct in‑house aerosol testing to confirm no toxic by‑products are generated at vaping temperatures (< 300 °C).
Typical flavour families:
- Fruit (e.g., Mango, Grape Ice) – High in ester compounds.
- Menthol/Mint (e.g., Ice, Cool Breeze) – Utilise menthol crystals, providing a cooling effect.
- Dessert (e.g., Vanilla Custard, Caramel) – Contain lactones and diacetyl derivatives, though many brands avoid diacetyl due to its link with bronchial issues.
3.4 Additives and Stabilizers
- Benzoic Acid – Forms nicotine salts and buffers pH.
- Ethylhexylglycerin – Acts as a mild humectant to maintain moisture.
- Citric Acid – Adjusts acidity for flavour balance.
All additives are kept well below thresholds that could affect lung tolerance, and each batch undergoes third‑party lab analysis to verify composition.
4. The Housing – Materials and Ergonomics
4.1 Outer Shell
Most disposable devices use medical‑grade polycarbonate (PC) or ABS plastics, chosen for durability, heat resistance, and a premium tactile feel. The shell often integrates a silicone gasket to seal the liquid reservoir, preventing leaks.
4.2 Mouthpiece
The mouthpiece is typically molded from food‑grade silicone or TPE. Its geometry influences airflow resistance; a narrower bore yields a tighter draw, while a wider aperture favors direct‑lung (DL) inhalation.
4.3 Airflow Channels
Internal airflow pathways are engineered with precision drilling or laser‑cut channels. Some devices use a dual‑air system: a primary channel for vapor flow and a secondary vent for cooling air, reducing coil temperature spikes and extending coil life.
5. Quality Assurance – From Production to Shelf
5.1 ISO Certifications
Both IGET and ALIBARBAR operate under ISO 9001 (Quality Management) and ISO 13485 (Medical Device Quality) frameworks. This ensures each production batch meets predefined specifications for component tolerances, battery safety, and e‑liquid consistency.
5.2 TGO 110 Standard
In Australia, the Therapeutic Goods Order (TGO) 110 outlines permissible nicotine concentrations, packaging warnings, and child‑resistant closure requirements. Compliance is confirmed through mandatory NSW Health inspections before products enter the market.
5.3 Third‑Party Testing
Independent laboratories conduct:
- Heavy metal screening (lead, cadmium, nickel) in coils and solder.
- Residual solvent analysis (acetone, ethanol) after manufacturing.
- Aerosol toxicology – Measuring carbonyl compounds (formaldehyde, acetaldehyde) at standard puff regimes (55 mL, 3 s draw).
Results are archived and made available upon request, underscoring the brand’s commitment to transparency.
6. Environmental Considerations
6.1 Battery Recycling
Li‑ion batteries are hazardous waste if discarded improperly. In Australia, the National Battery Recycling Partnership (NBRP) provides drop‑off points in major cities. IGET includes a QR‑coded recycling guide on each box to direct users toward local facilities.
6.2 E‑Liquid Packaging
Both brands prioritize recyclable high‑density polyethylene (HDPE) bottles for refill liquids, while disposable device packaging uses post‑consumer recycled cardboard.
6.3 Waste Reduction Strategies
- Refillable pod systems reduce single‑use waste.
- Biodegradable mouthpieces (PLA‑based) are in trial for future environment‑friendly models.
7. Common Misconceptions
| Myth | Reality |
|---|---|
| “E‑cigarettes are just water vapor.” | Vapor contains PG, VG, nicotine, flavour chemicals, and trace metal particles from the coil. |
| “Higher nicotine means more dangerous.” | Toxicity relates to concentration and delivery method; salt nicotine reduces harshness, allowing lower inhalation temperatures. |
| “All disposable vapes are the same.” | Device architecture, coil design, e‑liquid formulation, and safety circuitry vary widely between brands. |
| “Vaping is completely safe.” | While considerably less harmful than combustible tobacco, vaping still carries risks (e.g., nicotine addiction, potential respiratory irritation). |
8. Troubleshooting Quick Guide
| Symptom | Likely Cause | Remedy |
|---|---|---|
| Dry‑hit (harsh, burnt taste) | Depleted e‑liquid, clogged wick, coil overuse. | Refill (if refillable), store upright, replace device when puff count nears limit. |
| Weak vapor production | Low battery voltage, low‑resistance coil malfunction. | Allow battery to charge (refillables) or replace disposable. |
| Leaking liquid | Damaged seals, over‑filling (refillables), high‑PG formulation. | Inspect mouthpiece gasket, avoid over‑filling, switch to higher VG ratio. |
| Unusual taste (metallic) | Oxidized coil or contaminated wick. | Replace coil (refillable) or discard disposable; store away from humidity. |
9. Regulatory Landscape in Australia
- Nicotine Importation: Individuals may import nicotine‑containing e‑liquids for personal use (max 10 ml per shipment) under Prescription‑Only Medicine (POM) status, unless the product is classified as a Therapeutic Good.
- Age Restrictions: Sale of vaping products to anyone under 18 years is prohibited. Retailers must verify ID at point of purchase.

Frequently Asked Questions
Q1: What exactly is a “nicotine salt” and how does it differ from free‑base nicotine?
A: Nicotine salts are formed when nicotine is chemically bound to an acid (commonly benzoic acid). This lowers the pH, making the liquid smoother on the throat and allowing higher nicotine concentrations without harshness. Free‑base nicotine is the pure, unbound form, which provides a stronger throat hit and is typically found in lower‑strength e‑liquids.
Q2: Are the flavourings in e‑cigarettes safe to inhale?
A: The flavour compounds used are generally food‑grade and deemed safe for ingestion. However, inhalation safety is evaluated separately. Reputable brands conduct aerosol testing to confirm that no harmful degradation products (e.g., high levels of formaldehyde) are produced at typical vaping temperatures. Always choose products from manufacturers that disclose testing results.
Q3: How long does a disposable e‑cigarette actually last?
A: Lifespan is measured in puffs rather than hours. Devices like the IGET Bar Plus are rated for up to 6000 puffs, equating to roughly 5–7 days of moderate use (≈ 300 puffs per day). Real‑world longevity can vary based on puff duration, airflow settings, and nicotine concentration.
Q4: Can I refill a disposable e‑cigarette?
A: Disposable units are sealed at the factory and not intended for refilling. Attempting to open them may compromise the battery safety circuitry and void any warranty. For refillable convenience, consider pod‑style systems that are specifically designed for user‑added e‑liquids.
Q5: Is vaping less harmful than smoking cigarettes?
A: Public health bodies, including the Royal College of Physicians, acknowledge that vaping is significantly less harmful than combustible tobacco because it eliminates tar and many carcinogenic by‑products of combustion. Nonetheless, vaping is not risk‑free; nicotine remains addictive, and long‑term inhalation effects continue to be studied.
Q6: How should I dispose of the battery and device responsibly?
A: Lithium‑ion batteries must be taken to a recycling centre or a designated e‑waste drop‑off point. Many Australian councils and retail chains participate in battery take‑back schemes. IGET includes QR codes on packaging that direct users to the nearest recycling facility.
Q7: Do I need a prescription to buy nicotine‑containing e‑cigarettes in Australia?
A: Nicotine‑containing e‑liquids are classified as prescription‑only for import. However, disposable devices that contain nicotine are permitted for sale without prescription, provided they comply with TGO 110 standards and carry appropriate warnings. Always verify the product’s legal status before purchase.
Q8: What causes a “leak” and how can I prevent it?
A: Leaks often originate from a compromised seal, over‑filled reservoir, or high‑PG liquids that flow more readily. To prevent leaks: keep the device stored upright, avoid shaking vigorously, and, if using refillables, stay within the recommended fill line.
Q9: Can I use the same e‑liquid in any device?
A: Not always. Some devices are optimized for specific PG/VG ratios or nicotine strengths. High‑viscosity (high‑VG) liquids may not wick properly in low‑power, high‑resistance coils. Always consult the manufacturer’s recommended liquid specifications for optimal performance.
Q10: How do I know if a product is genuine and not a counterfeit?
A: Authentic IGET and ALIBARBAR products feature unique batch QR codes, holographic seals, and consistent packaging. Counterfeit items often lack these security features, have irregular fonts, missing warnings, or display unusually low puff counts. Purchase through authorized retailers or the official online store to guarantee authenticity.
