Protect Your Family


A mobile phone is the best survival tool we own. If we are lost in the woods, we can use the GPS or compass. If we are injured, we can call for help. We count on them in an emergency.

 

What can cause our best safety tool – a mobile phone – to fail when we need it most?

Mobile phones such as Apple’s iPhone 6S are designed to operate within certain temperature limits. There is a cap on the maximum operating temperature and anyone who has seen the warning “iPhone needs to cool down before you can use it!” understands that until you take it out from the sun or away from the heat source it will not turn on. There is also a minimum operating temperature but in this case, dropping below the temperature will not show a warning. Instead, the battery life will drop dramatically until the phone is dead.

Most importantly, normal, everyday use of the phone can place it outside a manufacturer's operating specification of 32° to 95° F. The phone can easily exceed these limits during a day at the mountain or a day at the beach. 

The chart below shows what happens when a phone is subjected to extreme cold with and without Therma-Phone™ protection.



Therma-PhoneProtectors are a sophisticated, yet compact and flexible system consisting of up to ten layers of specialized materials engineered to make a thermally stable zone around a mobile phone. It’s similar to placing your phone into a tiny soft portable thermally protected space like a thermos. Heat generated inside is retained when needed while external heat is reflected when needed.

Therma-Phone Protectors allow your phone to be placed in an outside pocket on your jacket where it is easy to access or stored safely in a backpack.
