Nitecore SUMMIT20000 - the ultimate cold-resistant power bank for extreme conditions

Imagine you are on an expedition deep in the mountains, where icy temperatures put your technology to the test. While conventional power banks have long since failed here, your new Nitecore SUMMIT20000 shows its true strength. This powerful, cold-resistant power bank reliably accompanies you through every adventure and keeps your electronic devices running, even in the most extreme temperatures down to -40°C.

Innovative heating technology - always reliable, even at the lowest temperatures

The integrated heating function of the SUMMIT20000 activates automatically at temperatures below 0°C and ensures impressive performance of up to 70% at -20°C. This means you always have enough power to charge important devices such as smartphones, GPS devices or cameras - ideal for expeditions in icy regions or extended winter tours.

Robust and lightweight UNIBODY carbon housing - ideal for on the go

Made from a high-quality UNIBODY carbon housing, the power bank offers maximum durability with minimum weight. The robust materials reliably protect the power bank against overcharging, short circuits, deep discharging, overvoltage and overheating and make it splash-proof in accordance with IPX5. This makes the SUMMIT20000 the perfect companion for demanding journeys and outdoor activities.

Flexible charging with Quick Charge and USB-C Power Delivery

The SUMMIT20000 has a Quick Charge-capable USB-A port and a powerful USB-C port with Power Delivery (PD), which enables fast charging with up to 20 W. Both ports can be used simultaneously, so you can easily charge multiple devices at the same time. Thanks to the special LOW Power function, the power bank remains active even when the power consumption is low - ideal for smaller devices such as GPS devices or smartwatches.

Pass-through function & simple operation

Another highlight of the SUMMIT20000 is its pass-through charging function. It can charge and discharge simultaneously as long as the energy output is lower than the incoming charge - ideal for connecting to a power source while you continue to use your devices.

An LED indicator shows the current charge level at all times, so you always know exactly how much energy you have left.

Easy handling thanks to intelligent capacity indicator

Thanks to a clear capacity indicator, you always have an overview of the remaining charge level. The integrated electronics allow devices to be charged safely and reliably and protect against overcharging, short circuits, deep discharging, overvoltage and overheating.
