Ocoopa UT4 Extreme – Heat, Light, and Energy in One Device

When the cold strikes, the Ocoopa UT4 Extreme shows what it's made of. Its 10,000 mAh battery provides up to 16 hours of constant heat – ideal for long nights in the hide or icy hours in the field. The robust camouflage housing is protected against dust and splashes according to IP56, making it perfect for any weather.

The temperature can be adjusted up to 53 °C over four heating levels. In Extra-Power mode, the device heats up noticeably in seconds, providing immediate warmth to cold hands. At the same time, the UT4 Extreme serves as a power bank with 18 W fast charging – allowing you to conveniently recharge your smartphone or headlamp on the go. The integrated LED light provides illumination in emergencies or when navigating in the dark – handy when searching for essentials in your backpack or when out late in the field.

With its compact design, grippy aluminum housing, and a weight of around 225 g, the UT4 Extreme feels comfortable in the hand and is easy to operate. A hand warmer that does more: warms, charges, lights – reliable and robust, just as you need it outdoors.
