The company, Better Mobile Xperience, positions these units as a durable alternative to industry-standard batteries, which faced multiple high-profile recalls and increased FAA scrutiny throughout 2025. While the marketing leans on the "solid state" label, the power banks actually employ a solid-liquid mixed electrolyte. This composition allows for mass production using existing manufacturing infrastructure, keeping retail prices more accessible than true solid-state alternatives.
Daniel Chin’s BMX Launches Semi-Solid State MagSafe Power Banks
After a successful Kickstarter run, accessory veteran Daniel Chin is bringing his SolidSafe power banks to the broader market under the new brand BMX. The devices utilize a semi-solid state electrolyte, a hybrid technology designed to address the safety and longevity concerns that have plagued traditional lithium-ion batteries recently.

BMX is launching the SolidSafe range in 5,000mAh and 10,000mAh capacities, with entry-level pricing at $79. A specialized 10,000mAh variant featuring a 512GB microSD slot is also available for $129. While the hardware supports 30W USB-C charging and includes an integrated cable, the wireless charging performance remains limited to 15W Qi2, falling short of the newer 25W Qi2.2 standard. Although currently sold out on the official BMX website, the products are expected to reach Amazon’s U.S. storefront in January.
