– One half has a built-in USB-C cable, while the other has a fold-out connector, eliminating the need for extra cables.
– The power output is 30W when used as one unit but drops to 20W per half when separated.
– The product is expected to launch in spring 2026 for approximately $80.
For travelers, families, and anyone who frequently shares a portable charger, the frustration of handing over your entire power bank is a familiar problem. A new innovation aims to solve this by letting you literally split your battery pack in two. The Champ Stack 10K from Nimble is a 10,000mAh power bank with a unique, shareable design that allows it to be broken into two separate, functional units. Announced at CES, this device combines the convenience of built-in cables with unprecedented flexibility for multiple users.
Resembling a standard portable charger, the Champ Stack features a clever segmented construction. With a simple twist, it separates cleanly into two independent 5,000mAh power banks. Each half possesses enough capacity to provide a full charge to a typical smartphone, allowing two people to power their devices simultaneously without being tied to one another. One section includes a built-in USB-C cable, while the other is equipped with a fold-out USB-C connector, ensuring both halves are ready to use immediately without searching for extra wires.
This innovative design does come with a minor trade-off regarding power delivery. When utilized as a single, unbroken unit, the Champ Stack can output up to 30 watts for faster charging. However, once divided, each individual half has a maximum output of 20 watts. This is still sufficient for efficiently charging most phones and tablets, though slightly less than the combined unit’s peak capability.
The practical applications for such a product are significant. It is an ideal solution for family trips, where parents and children often need to charge devices at the same time, or for colleagues navigating long conference days. It eliminates the common dilemma of loaning out your only power source and being left with a dead device yourself. For the individual who often carries multiple phones or gadgets, it provides a streamlined way to manage power needs without the bulk of several separate battery packs.
Priced at approximately eighty dollars, the Champ Stack 10K is scheduled for release in the spring of 2026. Its introduction addresses a specific, yet widespread, pain point in mobile device usage, offering a smart and physical solution to the social and practical challenges of battery sharing.
