The CE4 electronic cigarette is a type of clearomizer developed for e-cigarette systems, commonly paired with eGo-style batteries. It serves as an entry-level vaping component, designed for simplicity and affordability. Key characteristics include a transparent pyrex or plastic tank for e-liquid visibility, eGo threading compatibility, and replaceable coil heads typically rated at 1.8-2.4 ohms resistance.
Design and Features
Constructed with a standard 510/eGo connector, the CE4 features a removable base and mouthpiece, facilitating easy coil replacement. E-liquid capacity varies from 1.6ml to 2.0ml, depending on the variant. Coil options often include single wick designs using silica, which heat e-liquids to produce vapor.

Advantages and Disadvantages
- Advantages: Low cost makes it accessible for beginners; user-friendly with minimal setup required; wide availability in the vaping market.
- Disadvantages: Prone to leaking due to seal vulnerabilities; limited durability as plastic tanks can crack with acidic e-liquids; restricted airflow may result in muted flavor compared to advanced clearomizers.
Usage and Maintenance
Install the CE4 by threading it onto an eGo battery. To refill, unscrew the mouthpiece and pour e-liquid into the tank, avoiding the central chimney. Replace coils every 1-2 weeks based on usage, as gunk buildup affects vapor production. For cleaning, disassemble components and rinse with warm water to prolong lifespan; always prime new coils with e-liquid before vaping to prevent dry burns.
Professional Considerations
As an introductory device, the CE4 suits light nicotine users seeking a straightforward vaping experience. However, its lower vapor output and potential for issues recommend exploring sealed top-fill clearomizers for improved reliability. Always adhere to manufacturer guidelines and local regulations regarding coil compatibility and e-liquid types to ensure safe operation.
