20000mAh Low Temperature Power Bank

The Nitecore Summit 20000 power bank offers a high-capacity energy of 20000mAh, paired with an impressive low temperature resistance of -40°C/F. Unlike other power banks that lose efficiency in cold temperatures, the Summit 20000 can still charge a modern Phone up to 4.6 times even on top of Mount Everest. When temperatures drop below freezing, the Summit 20000's intelligent heating function activates, consuming ultra-low power to maintain optimal temperature and prevent power loss or inefficiency. The Summit 20000 also includes an insulated carrying bag and a reliable braided USB-C to C cable for seamless power transfer. If you're aiming for the top, make sure you bring along the Nitecore Summit 20000 power bank.

USB-A /USB-C Dual Ports

Equipped with dual ports, the Summit 20000 features a QC PD USB-C port capable of fast-charging the power bank itself or other devices at 18W and 20W respectively. It also comes with a USB-A QC output port, allowing for the charging of other electronic devices.When the quick charge is not desired for delicate devices such as bluetooth headphones or smart watches, the Summit 20000 has a one-touch low current mode.

Lightweight and Durable

The Nitecore Summit 20000 power bank is crafted with a unibody carbon fiber shell, making it both sturdy and exceptionally lightweight, tipping the scales at just 10.69 ounces. Its seamless design not only renders it impact-resistant up to 1.5 meters, but it's also rated IPx5 water-resistant, perfect for outdoor adventures.

5 of 5 I feel safer January 20, 2024
Reviewer: Mac Vo from littleton, CO United States  
I live in a severe weather area. We get down to sub zero temps.  I want something that will work in the temperature where most batteries just die.  Nitecore has solved the dilemma.  I feels better about my devices working better.  My mind is eased.

5 of 5 Small and powerful. July 15, 2023
Reviewer: Zachary Mayes from Davenport, IA United States  
This 20,000 mAh battery is smaller then some of my 10,000 mAh. They are exactly as described and was a wonderful purchase for my travels. Now I can carry more back up power in a smaller package. Drained and tested with a meter and they are 100% a 20,000 mAh capacity. So impressed, I bought a 2nd.  Highly recommend, just like all of their products, they are top notch!
