Designed with the innovative heating mode, the Summit 20000 is low temperature resistant to -40°C/-40°F. Equipped with the PI heating system, the Summit 20000 has high efficiency and high speed heating performance to ensure that the battery can work at an appropriate temperature for reducing the loss of power. The carbon fibre confined structure also guarantees the thermal insulation in low temperature environments.
The preheating function will be activated when connected to an external power source in low temperature environments. The Nitecore Summit 20000 will always be in heating status during preheating with no power consumption to maintain an appropriate temperature so that it can be used directly.
The Summit 20000 is made from a unibody carbon fibre shell without splicing to achieve optimal protection to deal with complex outdoor activities.
