Lithium battery fires caused by overheating cell phones have received a great deal of notice as these incidents increase in frequency.  This case is designed to keep your cell phone battery cool during the most vulnerable time for overheating–while charging. ChargeSafe™ is powered by FireIce Shield®, an advanced fire suppressant capable of extinguishing metal and other fires up to 10,000ºF. The ChargeSafe™ case protects the user and his or her environment by isolating the device while charging, storing or transporting. When a faulty or damaged battery overheats, the ChargeSafe™ case releases FireIce Shield® stored in the lining to suppress the fire.
