Exclusive Innovation: The World’s First Dedicated Sauna Phone Cooling Pouch Fills The Market Blank
For decades, sauna lovers have faced an unsolved dilemma: wanting to use their phones for music, photography, or social updates during sauna sessions, but fearing permanent phone damage from high temperatures.
Currently, there are no dedicated phone pouches designed specifically for sauna high-temperature scenarios on the global market.
Traditional waterproof phone bags, general storage pouches, and ordinary heat-resistant sleeves are only made for daily or low-temperature environments. They have zero active cooling performance and cannot offset the extreme high heat of saunas and steam rooms. Placing a smartphone in ordinary pouches will still cause rapid overheating, automatic shutdown, battery degradation, screen failure, and even irreversible hardware damage. No professional accessory has ever targeted and solved sauna phone overheating problems — until Coinno.
Redefine Sauna Phone Protection, Original PCM Constant Temperature Cooling Technology
Coinno officially launches the world’s first dedicated sauna phone cooling pouch, exclusively customized for high-temperature sauna, steam room, and hot spa usage scenarios. Breaking through the limitations of all common phone pouches on the market, this innovative product adds a detachable and replaceable Coinno PCM cold pack core.
Different from passive heat insulation of ordinary bags, our pouch adopts active phase-change constant temperature cooling technology. The pre-cooled PCM cold pack continuously releases stable cooling energy, neutralizes sauna ambient high temperature, and builds a safe constant-temperature isolation space for smartphones. It effectively prevents all high-temperature faults, allowing users to carry and use mobile phones freely in saunas for the first time.
