The Men's Heated Dual-Control Jacket is designed with 5 carbon fiber heating zones, strategically placed throughout the jacket for maximum warmth. This includes 2 zones on the front, 1 on the back, and 2 on the front pockets. These zones effectively warm your core body area, while 2 additional zones keep your hands toasty. The jacket also features a high-capacity 59Wh battery certified by CE/FCC, allowing for rapid heating of the elements to 140°F in just seconds. On the high setting, the battery provides up to 3.5-4 hours of warmth, while the low setting offers 9-10 hours. Additionally, the jacket has a USB Type-C port for charging mobile devices. For added control and battery conservation, there are separate power buttons for the hand and body areas. With 3 temperature settings indicated by red, blue, and white buttons, you can adjust the warmth to suit your environment. This versatile and comfortable jacket is perfect!
