Ever wished you could split your power bank in half so you and a friend could charge your phones simultaneously? Well, your wish has been granted. Nimble, a gadget maker, has unveiled the Champ Stack 10K power bank at CES 2026, and it's a game-changer. This innovative device allows you to break it in two, creating two separate 5,000mAh power banks. But here's where it gets controversial: while each half functions independently, the total power output is limited to 30W when used as a single power bank, compared to 20W per half when separated. Andrew Liszewski, a senior reporter who has been reviewing gadgets since 2006, is already eyeing this as his next upgrade. The Champ Stack 10K is set to launch in the spring of 2026 for around $80. So, are you ready to say goodbye to the days of sharing your charger? And this is the part most people miss: the Champ Stack 10K's unique design means you won't need to hunt for additional cables, as each half comes equipped with a built-in USB-C charging cable.
