Nitecore NB10000 Gen 4 Review: The Lightest & Most Compact 10,000mAh Power Bank! (2026)

When it comes to power banks, I'm a firm believer in keeping things simple and lightweight. And that's why Nitecore's latest offering, the NB10000 Gen 4, has caught my attention. This power bank is a prime example of how innovation can lead to a more efficient and user-friendly product, especially for those who value portability and performance.

The Power of Lightness

One thing that immediately stands out is the weight of this power bank. Weighing in at just 146 grams, it's an impressive feat of engineering. For context, that's lighter than a standard deck of cards! This level of compactness is a game-changer for outdoor enthusiasts, backpackers, and anyone who values every gram of their gear.

Energy Efficiency and Performance

The NB10000 Gen 4 boasts a 39Wh battery, which, in my tests, fully recharged an iPhone 15 Pro twice with a bit left over. That's a testament to its energy efficiency. And with an output of up to 22.5W, it can even keep your MacBook Pro topped up on the go. This power bank is a reliable companion for those who need to stay connected and charged during their adventures.

Design and Features

I appreciate the simplicity of the design. The four-element indicator for battery level is a welcome feature, providing a clear and quick way to check the power bank's status. The carbon fiber construction and IPX7 water resistance make it durable and suitable for various outdoor conditions.

One feature that might divide opinions is the animated RGB lighting. While it can be helpful in low-light situations, I find it a bit gimmicky. However, I do like the option to disable it, which is a thoughtful addition by Nitecore.

The Price Tag

The NB10000 Gen 4 comes with a premium price, retailing at $83.95. This is a significant jump from the previous generation, which started at $64.95. For some, this might be a deal-breaker, but for those who prioritize performance and portability, the price might be worth it. After all, when you're out in the wild, every gram and every watt-hour counts.

Final Thoughts

In my opinion, the Nitecore NB10000 Gen 4 is a testament to the power of innovation and a great example of how technology can enhance our outdoor experiences. It's a power bank that checks all the right boxes for me: lightweight, efficient, and durable. While it's not perfect, with a few minor quirks, it's a step in the right direction for power bank technology. If you're an outdoor enthusiast or an endurance athlete, this power bank is definitely worth considering.
