As a safety precaution, we do not recommend using Uwell products while they are charging. While Uwell devices are designed with safety features to minimise potential risks, it is always best to avoid using the device during charging. Charging a device requires a stable power source and uninterrupted charging process, and using it while charging may lead to battery-related issues or compromise the overall safety of the vaping experience. To ensure your safety and the longevity of your Uwell product, it's advisable to wait until the charging process is complete before using the device again.
