01. Industry leading innovation. Specially designed for low temperature environments.
Continuous use at -40 C°
Designed with the innovative heating function, the SUMMIT 20000 is a Power Bank resistant to low temperatures down to -40°C (-40°F) and can provide stable performance at these low temperatures, making the impossible possible.

02. Available capacity of the SUMMIT 20000 at -20°C (-4°F)
– At -20C° the available energy of the Summit 20000 reaches 70%
– A common Power Bank at the same temperature has only 10% of its capacity.
*Reported data has been tested in NITECORE laboratory for reference purposes only.

03. Ultra-low power consumption
Equipped with the PI heating system, the SUMMIT 20000 has high efficiency and high heating speed to ensure that the battery can operate at a suitable temperature to reduce power loss. The limited carbon fiber structure also guarantees thermal insulation in low temperature environments.

04. Low temperature heating function
SUMMIT 20000 will activate the low temperature heating function automatically when it is in use and its temperature is below 0°C / 32°F
thanks to the built-in intelligent temperature sensing modules.
– Dual Temperature Sensing Units : Ability to intelligently detect the temperature
– Red indicator light steady on: Heating function is on
* When SUMMIT 20000 has no input/output, short press the power button to activate the heating function due to low temperature.

05. Pre-heating function without energy consumption
The pre-heating function will be activated when connected to an external power source in a low temperature environment. The SUMMIT 20000 will always be in heating mode during pre-heating without power consumption to maintain the appropriate temperature so that it can be used immediately.
– No power consumption
– Charging protection
– Heating
* The reported data has been tested in the NITECORE laboratory for reference purposes only.

06. The package includes accessories that can withstand low temperatures.
– Insulating carry bag : Thermal insulation / Reduce heat loss
– The braided design of the cable effectively prevents cracking at low temperatures.
* It is recommended to use the Power Bank inside the insulating bag when the ambient temperature is equal to or less than 0C° 

07. Reach your peak

08. Single shell construction
The shell of the SUMMIT 20000 is made of seamless carbon fiber to achieve optimal protection to meet the complex demands of outdoor activities.
– Single body process offers durability and not easy to crack after falling.
– The welding process is likely to be damaged or cracked after a fall

09. Shockproof from drops up to 1.5 meters high and IPX5 Rated.
Resistant to low temperatures and fearless of accidental drops as well as rain and splashes.

10. Ultra light and small in size
It achieves a perfect combination of low temperature resistance, high impact resistance and high capacity in a small size with a weight of only 303g, about 33% lighter than common Power Banks.

12. Two charging programs. Two charging ports
Available with USB-C and USB-A ports, the SUMMIT 20000 can automatically detect different devices to provide a maximum output of 20W and a maximum input of 18W.
– USB-C (PD) : 20w output and 18w input
– USB-A (QC) : 18w output
* QC & PD charging programs are not available when the temperature is below 5C°

13. Low Power Mode
Long press the power button to access the low power mode. This function is available for both USB-A and USB-C ports, suitable for charging low current devices including Smart Watches, Smart Bands, Wireless Headphones and more.
– To indicate the operation, a white indicator light lights up steadily

14. Outstanding Energy Density
Built-in 20,000mAh large capacity Li-ion battery
Energy density of SUMMIT 20000: 2002007: 254mWh/g
* Energy density formula:
(Battery capacity × battery voltage) / (Total weight of SUMMIT 20000)
Note: The weight of the actual products may vary slightly.
* The above mentioned data comes from the NITECORE laboratory

15. Power level indicator
