Frequently Asked Questions
- What should I do if e-cigarette chip leaks e-liquid?
E-liquid leakage (liquid ingress) into the e-cigarette chip can have negative impacts on device performance and user experience. It is recommended to check the e-liquid container, avoid overfilling, maintain cleanliness, replace the atomizer, adhere to temperature requirements, and use high-quality e-liquids to address this issue.
- How do I disassemble and replace the chip in a rechargeable e-cigarette?
Disassembling and replacing the chip in an e-cigarette typically requires professional skills and tools, as it involves the internal components and circuitry of the e-cigarette device. If you lack experience or familiarity with the construction of e-cigarette devices, it is advised not to attempt disassembling and replacing the chip on your own, as it can potentially damage the device and pose safety risks.
