Nimble has turned a gimmick into a product: the new Sharepower is a magnetic power bank that can break apart into two independent chargers, each with its own 5,000 mAh battery and connector. The combined unit costs $80, and while that is a little rich for a 10,000 mAh battery pack, the trick here is flexibility – one device for two people, or one brick that becomes two when your phone and earbuds are both begging for mercy.
The Sharepower is the retail version of the Champ Stack 10K shown at CES 2026, so this is not just concept fluff with pretty photos. The two halves stick together with magnets and look like one accessory, but they are really separate chargers joined at the hip. That also explains the odd hardware split: one half has a short cable, while the other carries a built-in USB-C plug that sticks out of the body.
Nimble Sharepower battery and charging specs
On paper, each half is modest: 5,000 mAh and 20 W charging. Put them together, though, and the package does something a normal stacked battery would not. Capacity adds up as expected, but output rises to 35 W instead of simply doubling the single-unit rating. That makes the Sharepower less of a novelty and more of a small tactical charger for travel bags, shared tables, and the eternal ”who has cable?” panic.
- Price: $80
- Battery: 10,000 mAh total, split into two 5,000 mAh halves
- Charging output: 20 W per half, 35 W combined
- Design: magnetic split-body charger with USB-C cable and built-in USB-C plug
A clever shape in a crowded power-bank market
Split batteries are not a new idea, but most brands stop at making something smaller or lighter. Nimble is clearly betting that a more social form factor will do the selling, especially as accessory makers keep looking for ways to stand out in a market where plain rectangles are painfully easy to ignore. The downside is obvious: you are paying for clever engineering and convenience, not for maximum capacity per dollar.
The real question is whether buyers want a power bank that behaves like two accessories in one. If Nimble can keep the charging experience simple, the Sharepower could carve out a niche among travelers and coworkers. If not, it may end up as one of those products people admire for 30 seconds, then buy the cheaper brick anyway.
