Nimble’s Futuristic Power Bank Unveiled at CES 2026

At CES 2026, the company Nimble unveiled a rather unusual power bank, the Champ Stack 10K. This is effectively two separate portable battery packs that can be assembled into one like a transformer.

As seen in the photo, the design is straightforward to understand. Champ Stack 10K is essentially split into two halves, which are connected by magnets. Each half contains a 5000 mAh battery, and it can be fully used separately.

Combining the parts not only doubles the capacity but also increases the power from 20 to 30 watts. Notably, one half comes with a USB-C cable, while the other has a connector protruding directly from the case. The new product will be released in the spring at a price of approximately $80.

Experts at the CES noted that the Champ Stack 10K sets a new standard for modular design in portable charging technology, emphasizing its potential convenience and versatility for users. A renowned tech analyst commented, “The Champ Stack 10K’s modular design offers a functional solution for varying power needs on-the-go, representing a significant step forward in user-centered technology.”

As demand for more adaptable and efficient power solutions grows, products like the Champ Stack 10K might see increased popularity, making them a frontrunner in the competitive power bank market. Competitors will have to innovate swiftly to keep pace with modular functionalities now entering the mainstream.
