10,000 mAh easily shared between two: Nimble introduces a modular power bank with built-in cable and retractable connector

The American company Nimble has introduced one of the most unusual power banks on the market — Champ Stack 10K, which is a modular battery with the ability to split into two independent parts.

What is known

Champ Stack 10K consists of two halves connected by magnets and a USB-C connector. Assembled, it is a single 10,000 mAh battery with support for up to 30W charging, and if you split the case, the user gets two separate 5,000 mAh power banks, each capable of delivering up to 20W of power.

This format allows you to charge two devices simultaneously, share half the battery with a friend, and use different cables and connectors.

Each half is equipped with its own connection method: one part has a built-in USB-C cable, the other — a retractable USB-C connector. This solution eliminates the need to carry additional wires.

The Champ Stack 10K case features a digital display that shows the battery level of each device half.

Champ Stack 10K will go on sale in spring 2026 for $80.
