A Smarter Standard for Safety

Lithium-ion battery fires are unpredictable, fast-moving, and dangerous. In this demonstration, witness the stark contrast between an unprotected laptop in thermal runaway and one secured inside the CellBlock Safe Charge D-Series Sleeve. This isn’t just about protecting a device—it’s about safeguarding your safety, your environment, and your peace of mind—whether you're working from a hotel suite or unwinding at home.

Watch below to see why proactive protection matters.
