LAS VEGAS, NV—Marking a breakthrough in both lithium-ion technology and the fine art of gritted-teeth generosity, accessory maker Nimble has announced the Champ Stack 10K, a power bank explicitly engineered for people who dream of never fully giving, nor fully keeping, a portable charger. Unveiled at CES this week, the device can be physically snapped into two functional halves, allowing users to maintain the illusion of friendship while hoarding personal battery reserves.

“Finally, I can lend someone power without feeling like they’re draining my life force,” said product tester Avery Feldman, moments before breaking the device over her knee while glaring at her roommate. “It’s the next best thing to just saying no.” Each half boasts a dignified 5,000mAh capacity and, according to Nimble, a built-in sense of superiority over anyone using a phone with less than 30% charge.

Industry analysts predict the Champ Stack will revolutionize both mobile charging and passive-aggressive relationships. “It’s amazing—they’ve gamified sharing,” remarked tech influencer Dakota Blount, who unboxed the device before immediately hiding one half. “This is the future of communal living, right here.”

Nimble CEO Lyle Fennel, speaking exclusively to journalists outside a CES charging station, described the product’s inspiration: “We looked at the KitKat bar and thought, ‘What if that, but for people who fear emotional intimacy?’ Also, it’s easier to sell two chargers if you just glue them together first.”

The Champ Stack 10K ships next month, alongside a forthcoming app that tracks how often you keep the bigger half, purely for data, not judgment.
