Alpine skiing, snowboarding, cross-country skiing, ski touring, snowshoeing, winter fatbiking, snowmobiling, quad and ATV on winter trails, ice climbing, ice skating, winter hiking: the Summit Air also recharges your heated gloves, socks, base layers and heated clothing to stay warm in any conditions.

22.5W Fast Charging and Extreme Cold Features

Its RGB port indicators make it easy to locate the ports in the dark (night skiing, inside a vehicle). Its 4 blue LEDs display real-time battery level. The glove-friendly physical button lets you check battery status without exposing your hands to the cold. ⚠️ Do not charge below 0°C, even though discharge operates down to -40°C.
