The NITECORE SUMMIT 20000 is a low temperature resistant power bank, specially designed for low temperature environments. It can provide continuous use at -40°C (-40°F) and stable output in low temperature environments, making the impossible possible. 

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. Besides, the available capacity of the SUMMIT 20000 at -20°C (-4°F) is approx. 70% while the conventional power bank is not available or has 10% available capacity only at this temperature.

The SUMMIT 20000 will activate Low Temperature Heating Mode automatically when its temperature is below 0°C / 32℉ and there is input or output, due to the integrated intelligent temperature detection modules. In addition, the preheating function will be activated when connected to an external power source in low temperature environments. The 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.
