ThermaGuard is the world's first actively temperature-regulated phone case — keeping your device safe and functional whether you're carving powder at 0°F or hiking desert trails at 110°F.
Smartphones are precision electronics with a narrow operating window — typically 32°F to 95°F. Outside that range, batteries die without warning, screens freeze up, and critical components fail permanently. For skiers, snowboarders, hikers, and outdoor workers, a dead phone isn't just inconvenient. It's dangerous.
Lithium-ion cells lose up to 40% capacity below freezing — your phone can shut off instantly, with no warning, mid-slope.
Sustained heat above 95°F causes thermal throttling, battery swelling, and permanent long-term damage to your device.
Current cases offer passive insulation at best. Nothing on the market actively monitors and manages your phone's temperature in real time.
ThermaGuard doesn't just insulate — it actively senses and responds. Built-in thermal elements heat or cool your device on demand, keeping it in the optimal zone no matter the conditions.
Polyimide film heating elements warm your device when ambient temperatures drop below the safe threshold — no more cold-killed batteries on the chairlift.
Cold ProtectionSolid-state Peltier modules actively draw heat away from your device, preventing thermal throttling and battery damage during hot-weather use or intensive apps.
Heat ProtectionOnboard temperature sensors monitor your device in real time, automatically switching between heating and cooling modes without any input from you.
Auto ControlMagSafe-compatible wireless charging means ThermaGuard never gets between you and a full battery. Just place and charge — seamlessly.
SeamlessEngineered to withstand the same conditions your phone faces. Impact-resistant construction that protects from drops alongside temperature extremes.
Drop ProtectionFrom ski slopes to desert trails, ThermaGuard is the only phone case you need year-round — engineered for the full range of the elements.
Any ConditionWe've engineered ThermaGuard to deliver professional-grade thermal protection at a price that makes sense for everyday consumers.
Whether you're a potential investor, retailer, or just want to be first in line — we want to hear from you.
