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.

A 20,000mAh power bank designed for extreme cold conditions. Customers praised its reliable performance in sub-zero temps, with one noting it "worked well in the cold" and another reporting use at -20°F in the Arctic. Highly rated for lightweight, compact design and multiple phone charges. One customer noted the included case was too tight, causing stitching to break.
I've had this for a short time, but it seems to be what it aspires to be. I used it to power a heating pad for an ailing cat of mine. It helped her, so I'll continue to use it for at least this purpose. Happy to have found it.
I bought this to take on long cold weather camping/hiking trip. First, some of this could be my error since I did not keep it warm. I only got one charge out of it for my iPhone, sad. Since I've been back in normal weather it seems to be fine. So I figure if I'm using this in cold weather camping/hiking it needs to be kept warm, on my body, the whole time. Not always ideal. While I can still use it in day to day life, I will be looking for something else for cold weather camping/hiking.
Charged my iPhone 15 Pro from 1 to 100% spending 75-80% of it's capacity judging by the LED indicators. If this is not the case of me unluckily receiving a defective device, I wouldn't recommend. Returning mine for a full refund.
Great portable power for any conditions!
I have not tested it yet but it charged correctly.
Untested - Purchased the Nitecore Summit 20000 power bank for a high altitude 12 day trek in the Andes this July. Looking forward to see how the power bank performs.
Haven't tried yet but confident it will work up to 6000 meters at the Mt. Everest Base Camp. Fingers crossed!
Fantastic. Just what I need for ultra light camping and hunting above 11ooo ft elev in rocky mountain Timberline mule deer and mountain goat basins. Spent two day at 12k ft elev temps were between 6° f and 35,°f had phone service watched a movie charged phone 3 times and pumped air mattress up twice with summit 20k and still had almost full battery bank left on summit 20k
I charged it up using Nan electricaln outlet. And then used to charge my phone 3-4 times. It's a solid power bank.
I haven't tried the solar charging panel yet.
Used it out ice fishing worked great
It’s amazing! Taking it on Kilimanjaro to test it out on the cold too!
I purchased this unit because my other power bank kept shutting down to the extremely cold conditions we currently have in southeast PA. I got this, charged it, and then put it out. With the bag that came with the unit, the power bank lasted for over 3 1/2 days running my BirdWeather PUC through a couple of nights which were in the single digits. Very impressed.
Seems like it will serve me well in the cold.
Works great in cold weather!
Power bank works amazingly but the case is nearly unusable. The case is ment to be snug but I found it so tight that I broke stitching trying to put the power bank inside. Nitecore did replace the case without issue.
This is among the most compact and lightweight power banks you'll find, and being designed for winter activities is a bonus! I'll be relying on it heavily this winter. Thanks NiteCore!
it worked well in the cold. Thats allot to ask for. Poor conditions dont seem to be a thing that bother its function at all. Overall I would consider it an excellent product.
Works great
Great so far.
I will be using this on an Everest Base Camp trek next year with a climb to Lobuche East peak (20,075 feet). Already used it on one backpack trip and it performed flawlessly.
Good
Works as advertised, even in the Arctic Circle at -20!
Very pleased
Love
It was great charged the phone fine lightweight and tough and durable
It’s a rarity these days to find a company with very excellent customer service! I was quickly helped with an issue that was my fault at no extra cost to me. I’m very thankful!!
This is amazing, holds a charge, and I can depend on it regardless of the temperature!
Purchased the product to take Everest base camp and Denali. Can’t wait to test it out.
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.
Love this site - easy to navigate, lots of product info and great technology!
