Nimble has turned a clever CES concept into a real product: the Sharepower, a portable charger that can snap apart into two independent battery halves. Each side carries 5,000mAh, each has its own connector setup, and when you lock them together the whole thing looks like a single 10,000mAh power bank with a higher output ceiling than either half can manage alone.
That’s the hook, and it’s a good one. Most power banks chase bigger numbers or faster charging; Nimble is trying to make the hardware itself more flexible, which is the kind of idea that sounds gimmicky until you actually need to charge two devices from one pocketable slab.
Two batteries, one magnetic shell
The Sharepower is essentially two separate batteries held together by magnets. One half includes a short cable, while the other has a USB-C plug protruding from the body. Break them apart and you get two standalone chargers; keep them together and you get a single unit with a combined 10,000mAh capacity.
That modular trick is the entire pitch, and it is more practical than many product demos that survive exactly one trade show. In a crowded accessory aisle packed with near-identical black bricks, any design that changes how people carry or share power gets attention fast.
35W together, 20W apart
The charging math is the other interesting part. Each half tops out at 20W on its own, but when combined, the linked device can deliver up to 35W. That means the magnetic pairing does more than just make the product look tidy; it actually changes what the battery can do.
- Capacity: 5,000mAh per half, 10,000mAh combined
- Output: 20W per half, up to 35W when joined
- Price: $80
A smarter answer to a crowded accessory aisle
Nimble first showed the idea at CES 2026 under the name Champ Stack 10K, so Sharepower is not a random one-off experiment. It is the sort of accessory move that makes more sense as phones, earbuds, and tablets all keep pulling on the same charging cable at once. The question now is whether buyers want a split-and-rejoin battery enough to spend $80 on it, or whether they will simply buy another plain power bank and call it a day.
