Nitecore Summit 20000 Power Bank | 20,000 mAh | Cold Resistant to −40 °C
20,000 mAh at −40 °C — the Summit 20000 for expeditions, winter camping and anyone who needs power in extreme cold.
Power at −40 °C – when ordinary power banks have long given up
The Nitecore Summit 20000 is a cold-resistant power bank that reliably delivers power even at −40 °C. While conventional Li-ion power banks fail below −10 °C, the Summit 20000 uses specially engineered cell chemistry for extreme cold. 20,000 mAh (77 Wh) in a carbon fiber shell with USB-C (20 W) and USB-A (18 W) output, IPX5 splash protection and 1.5 m drop resistance. Includes an insulation carrying bag for additional cold protection.
Cold resistant to −40 °C
Where other power banks fail – the Summit 20000 keeps delivering
Standard Li-ion cells lose capacity rapidly in cold and shut down around −10 °C. The Summit 20000 uses optimised cell chemistry that still delivers energy to your smartphone, GPS or headlamp at −40 °C. The included insulation carrying bag retains body heat around the device and maximises capacity in extreme cold.
USB-C at 20 W – fast charging even in the cold
The USB-C output delivers up to 20 W (5 V/3 A, 9 V/2.22 A, 12 V/1.68 A) for fast charging. USB-A supports up to 18 W (5 V/3 A, 9 V/2 A, 12 V/1.5 A). Combined dual-port output is 15 W. The USB-C input (5 V/2.4 A, 9 V/2 A) recharges the Summit 20000 – ideally at room temperature for optimal cell longevity.
IPX5 splash protection and 1.5 m drop resistance
The carbon fiber shell with IPX5 splash protection withstands snow, rain and sweat. 1.5 m drop resistance protects the device on rocky terrain. At 77 Wh the Summit 20000 is well below the 100 Wh airline limit – perfect for flying to your next expedition.
