Accessory maker Nimble announced a new power bank at CES 2026 that will appeal to anyone who's 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's 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.
