One of our favorite accessory makers, Nimble, which creates eco-friendly accessories, dropped something intriguing at CES 2026. The company offers a solution for those who may need to share or loan out their portable charger.
Meet the new Nimble Champ Stack 10K, a 10,000 mAh battery that can be split into two 5,000 mAh batteries—with each side providing built-in USB-C cables and held together magnetically. And when split apart, 5,000 mAh is enough for a full charge or enough to get close to it. Both parts of the Champ Stack together offer 30W charging speed, and 20W separately.
Nimble also partnered with Flint, a tech company specializing in paper-battery technology, for a line of travel accessories, which include a passport wallet, a slim wallet, a keychain, and a luggage tag. It’s utilizing Nimble’s vegan leather color options and Flint’s 1mm thick paper and wirelessly-chargeable batteries. Yup, Flint uses a cellulose-based material that’s biodegradable and rechargeable. These new accessories support Apple’s Find My network to keep track of them.
The Nimble Champ Stack 10K is set to arrive later this spring for $80. It definitely sports an impressive design, and I’m curious to see how well the magnets hold up over time. But there’s no word yet on when the Nimble x Flint products will become available or on pricing. This is quiet innovation at its best—at least on paper.
