Nimble Champ Stack 10K Splits Like KitKat

Accessory maker Nimble announced a new power bank at CES 2026 that will appeal to anyone who has had to reluctantly share or loan their portable charger to someone else. The Champ Stack 10K looks like a typical 10,000mAh power bank that has jumped on the built-in charging cable bandwagon, but it has one interesting difference: you can break it in two without damaging it so two people can charge their devices separately.

Once separated, each half of the Champ Stack 10K functions as a standalone 5,000mAh power bank. This capacity should be enough to fully revive a dead smartphone. One half ends up with the power bank's built-in USB-C cable, while the other features a USB-C port. The device is one of the first power banks you can safely break apart.

The Champ Stack 10K introduces a unique form factor to the portable charging market. Nimble designed the device to resemble a KitKat bar, allowing users to snap the power bank into two separate pieces. This functionality solves the problem of sharing a single charger between multiple devices or users.

Unlike traditional power banks that require cables or adapters to share power, the Champ Stack 10K physically separates. The design ensures that neither half is damaged during the process. Once snapped apart, both pieces operate independently.

The device was announced at CES 2026, highlighting a trend toward modular accessories in consumer technology. The ability to split a 10,000mAh battery into two 5,000mAh units offers flexibility for users who travel or commute in pairs.

The Champ Stack 10K features a total capacity of 10,000mAh. When the unit is separated, each half contains 5,000mAh of capacity. Nimble has engineered the internal components to ensure that the split does not compromise the battery integrity or safety.

Connectivity options are distributed between the two halves. One side retains the built-in USB-C charging cable, while the other side features a USB-C port. This distribution ensures that both separated units remain functional for charging different devices.

The product joins a growing market of power banks with built-in cables, but stands out due to its modular nature. The 5,000mAh capacity in each half is sufficient to charge most modern smartphones from 0% to 100% at least once.

Nimble is an accessory maker known for producing tech gear. The announcement of the Champ Stack 10K at CES 2026 suggests the product is nearing a release phase. The concept of a "breakable" power bank addresses a specific pain point for consumers: the reluctance to loan out a personal charger due to the difficulty of getting it back.

By allowing the power bank to split, Nimble allows users to share power without giving up their entire device. The design encourages shared charging experiences in social or travel settings. The product is positioned as a solution for shared power needs.

The innovation adds to the lifestyle technology category, blending practical utility with a novel design. As portable power becomes essential for daily life, modular designs like the Champ Stack 10K may become more prevalent.
