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.
Once separated, each half of the Champ Stack 10K functions as a standalone 5,000mAh power bank, which should provide enough capacity to fully revive a dead smartphone. One half ends up with the power bank’s built-in USB-C charging cable, while the other has a fold-out USB-C connector, so you don’t have to worry about hunting for additional cables. The only downside of this unique design is that, when used as a single power bank, the Champ Stack 10K’s power output maxes out at 30W, but when split in two each side maxes out at 20W, according to Wired.
As my family’s designated charger who frequently finds himself traveling with pockets full of phones all tethered to a single 10K Anker power bank, Nimble’s Champ Stack is now at the top of my upgrade list. It’s expected to launch in the spring of 2026 for around $80, according to CNN.
