Did you know that maintaining optimal body temperature can improve your performance by up to 25% and significantly enhance your comfort throughout the day? For those dealing with muscle soreness or sweltering summer heat, ZERA MAX 2 delivers an innovative dual function—cooling and heating—activated with a simple button press. The device harnesses Thermotherapy Tech alongside AI-controlled temperature, an AI-moderated chipset, and a large-diameter turbine fan, making it perfect for active users and anyone wanting consistent comfort throughout their day.
But does this futuristic comfort device live up to the hype? Let’s break it down.
Design & Build Quality
Compact. Durable. Stylish. The ZERA MAX 2 weighs just 295 grams, making it one of the most lightweight wearable cooling/warming devices on the market. Its sleek design combines ABS plastic and aluminum alloy construction, delivering durability without compromising on looks or portability for extended daily use. Its dimensions—77 x 96 x 120 mm—are compact enough to wear all day long, while the included long strap adds versatility for different body types and use cases.
Rapid Cooling, Soothing Warmth: Dual Functionality
Forget the days of separate gear for hot and cold therapy. ZERA MAX 2 features both cooling and heating functions:
- Cooling Range: 70°F–59°F (21°C–15°C)
- Heating Range: 104°F–113°F (40°C–45°C)
Thanks to its Nanotech thermal generator and a large diameter turbine fan, cooling is rapid and highly effective.
AI-Controlled Comfort Technology
The ZERA MAX 2 is a next-generation AI wearable that provides responsive temperature control, offering rapid cooling and soothing heat therapy. Powered by Thermtech innovation, an AI-moderated chipset, and a large diameter turbine fan, MAX 2 effectively relieves muscle aches and promotes relaxation.
Three Therapy Modes to Match Your Needs
MAX 2 provides three versatile modes to suit different wellness goals:
Cold Therapy: Reduces swelling and inflammation through vasoconstriction. Perfect after exercise or injury recovery.
Heat Therapy: Eases muscle stiffness and soreness by relaxing tense muscles and decreasing spasms. Heat promotes circulation to targeted areas, accelerating healing and reducing the appearance of bruises.
Contrast Therapy: Why choose just one when you can have both? Contrast therapy combines hot and cold for the best of both worlds. The cold tackles inflammation and pain, while the heat boosts circulation. Switching between the two helps your muscles and joints recover faster and feel better sooner.

Smart App Control
Take full control of the ZERA experience using the ZERA App. Through its intuitive interface, users can make precise power adjustments from 0 to 100, set custom timers effortlessly, and activate intelligent AI Temperature features.
Battery Life
Powered by a robust 8000mAh battery, the ZERA MAX 2 delivers up to 17 hours of continuous operation. The convenient USB Type-C charging port supports 10W charging power, ensuring compatibility with most modern charging accessories for convenient recharging.
