Phoozy thermal capsules protect smartphones from physically destructive temperature swings similar to how Silent Pocket privacy cases protect them from personally destructive cellular, Bluetooth, WiFi, GPS, RFID, and NFC signals. Phoozy blocks out heat and cold; Silent Pockets block out skimmers and trackers. Both aim to keep your phone safer from the demons that hunt it.
Now all you have to worry about is all the demons that hunt all the rest of your stuff. Alexa! Order me a Buffybot!
In Phoozy's case, becoming a thermal capsule for your smartphone required some help from the astronauts. Its composition is an adaptation of spacesuits, made from the same materials that protect NASA's finest from extreme extraterrestrial environments. A combination of insulating, reflective, and impact-resistant layers both shield the phones they cover from the sun, high heat, and temperatures as cold as -20 degrees F, and provide military-grade protection from drops and water encounters. In fact, Phoozy compares its Impactor Core Layer to a life jacket - if you drop your Phoozy-cased phone into the water it will become a phloaty.
Additional Phoozy layers include a Chromium Shell that reflects 90+% of solar radiation, and SpaceTech Penetration Layer for toughness and insulation, and a Soft Touch Protective Liner that covers phone screens to guard against nicks and scratches.
Phoozy thermal capsules are available for iPhone 5 and up, Google Pixel and Pixel XL, Samsung Galaxy S, S8, and S8+, and LG, Motorola, Kyocera, HTC, and Microsoft smartphones.
