Nimble Unveils SharePower, a Split-Design Power Bank

Nimble introduced the SharePower, a 10,000 mAh USB-C power bank that can be snapped in half to become two 5,000 mAh chargers. The device entered the market on June 15, 2026, priced at $80, and is sold through Nimble’s website and Apple retail stores.

When assembled, SharePower delivers up to 35 W across three devices; each half supplies 20 W when separated, allowing up to four devices to charge simultaneously. The unit measures 2.8 × 3.1 inches, is about an inch thick, and weighs 7.6 ounces (216 g). Magnetic pogo-pin connectors join the halves, and each side includes a built-in USB-C cable—one a braided lanyard, the other a pop-out connector. An LCD panel shows combined charge percentage, while individual halves display their own levels via LEDs or a numeric readout. The charger is offered in white, blue, and pink.

Co-founder and CEO Ross Howe described the load-balancing system as a “technical challenge” solved by collaborating with a chipset provider to ensure even power distribution when the halves reunite. Nimble confirmed the $80 price and the June 15 launch across its online store and Apple.com.

Android Police and CNET evaluated the SharePower with a Motorola Edge 70 Fusion, a Google Pixel 7 Pro, and an iPhone 17 Pro Max. All devices charged without overheating, and the advertised 20 W per half and 35 W combined outputs were confirmed. Reviewers noted that the magnetic halves often detached when the unit was jostled in a bag, and a faint electronic or crackling sound was audible during iPhone charging.

The design lacks a mechanical lock, so the magnets can separate unintentionally—a point Android Police called “annoying” and a potential risk during active charging. Both outlets reported a low-level crackling noise when the charger powered an iPhone, with no explanation from Nimble. Additionally, a single 5,000 mAh half cannot fully charge an iPhone 17 Pro Max, and the 20 W output is slower than the higher wattage iPhone fast-charging standard.

Android Police describes frequent accidental splits, whereas CNET mentions only occasional inconvenience, indicating differing user experiences of magnet strength. Neither source identifies the cause of the iPhone-specific crackling sound, and Nimble has not issued a technical comment on either issue.

Nimble says it will monitor early feedback and may release firmware updates to improve magnetic retention and address the iPhone charging noise. Future color options and accessory bundles are hinted at on the company’s website, suggesting incremental refinements rather than a redesign.
