The Nimble SharePower power bank is a $79.95 portable charger that divides its 10,000mAh total capacity into two magnetically connected 5,000mAh modules, according to product specifications covered by Android Central. Designed to solve the logistical challenges of sharing a single battery pack during group travel, the device supports a combined 35W USB-C Power Delivery output in its docked configuration, known as Stack Mode, and up to 20W per module when separated into Share Mode.
Engineering the Split-Battery Architecture
Portable power banks traditionally rely on a single physical brick with multiple ports, forcing users to remain close together while tethered to the same device. Nimble addresses this hardware bottleneck with a magnetic modular design. According to specifications detailed by tech outlets, magnetic pins lock the two 5,000mAh cells together to allow a combined output of up to 35W via USB-C Power Delivery while charging up to three devices simultaneously. When users detach the modules from one another, each section operates as a standalone 5,000mAh power bank capable of delivering up to 20W PD on its own.
The primary module houses a dynamic TFT LCD display or LED power indicator, depending on retail specifications, alongside a foldaway USB-C connector. The secondary module stores a fabric USB-C cable that doubles as a carrying strap when docked. The device is available in four colorways: black, pink, white, and blue.
Real-World Utility on Group Excursions
Splitting the battery eliminates the physical tether that usually accompanies shared charging accessories. According to hands-on testing by Android Central reviewer Namerah Saud Fatmi, dividing the battery allows one user to take a 5,000mAh module and walk away entirely—such as heading to hotel reception or a restaurant—leaving the other half behind without sacrificing personal device uptime. While splitting the pack reduces individual capacity down to roughly 1.5 to 2 total phone charges depending on the handset, the tradeoff prioritizes spatial freedom over raw, single-unit endurance.
Managing Asymmetric Charge States and Pricing
Dividing a battery introduces a circuit-management challenge: what happens when one module drains significantly more than the other during daily use? Reconnecting the two halves triggers an internal charge-balancing sequence. As Nimble co-founder and CEO Ross Howe explained to Wired, this mechanism enables a fuller module to replenish a drained counterpart until the energy levels of both sides match.
Priced at $79.95, the SharePower carries a noticeable premium over standard single-unit 10,000mAh blocks available on the market. However, its modular execution offers a specialized tool for frequent travelers and coordinators dealing with companions who travel without their own charging hardware.
