The CCELL M4B Pro is a 510-thread battery designed to provide users with enhanced control, flexibility and safety in cartridge vaping.

The device offers three adjustable voltage settings (2.8V, 3.2V, and 3.6V), enabling users to tailor vapor output based on cartridge type and personal preference. A built-in 10-second preheat function helps improve oil flow for smoother draws, particularly with thicker concentrates.

For safety and usability, the M4B Pro includes a child-resistant locking system activated via a 5-click sequence. It also includes LED indicators for battery status and operating feedback, along with USB-C charging for convenient recharging.

With its slim stainless steel body and standard 510-thread compatibility, the M4B Pro is positioned as a compact, user-friendly battery focused on control, safety and consistent performance.
