Semi-solid state MagSafe power banks arrive from the founder of Hyper

"A new company called BMX, founded by accessory royalty, has emerged from Kickstarter to make its SolidSafe semi-solid state power banks available to the general public. Like the Kuxiu semi-solid state power banks I've recently reviewed, BMX's promise to have twice the longevity and be safer than traditional power banks, which have been the subject of recall after recall in 2025, attracting the attention of the FAA and airlines."

"Both BMX and Kuxiu insist on calling their batteries "solid state," but they're not - instead they use a solid-liquid mixed electrolyte. Nevertheless, they still have advantages over traditional batteries and can be mass produced using existing manufacturing processes to help keep costs down. The power banks cost about twice as much to purchase but last over twice as long so you'll likely come out ahead in the end, and without any burns or property damage."

"The SolidSafe range is available in 5,000mAh and 10,000mAh capacities with prices starting at $79. There's also a 10,000mAh model with a microSD slot (max 512GB) that lists for $129. Unfortunately, they're all stuck on older 15W Qi2 MagSafe-compatible wireless charging, instead of the newer Qi2.2 that can handled 25W. Otherwise, you get 30W USB-C in/out and a USB-C cable integrated into the lanyard, which is handy."

BMX (Better Mobile Xperience) launched SolidSafe semi-solid-state power banks after a Kickstarter campaign. The company is led by Daniel Chin, founder of Sanho and creator of Hyper-branded accessories. SolidSafe uses a solid-liquid mixed electrolyte rather than a true solid-state chemistry, yet offers greater safety and roughly double lifespan compared with traditional lithium-ion packs. The units withstand drilling, bending, and cutting better than all-liquid batteries and can be mass-produced with existing manufacturing lines. Available capacities are 5,000mAh and 10,000mAh, starting at $79, with a 10,000mAh microSD model listed at $129. Chargers provide 30W USB-C in/out, a 15W Qi2 MagSafe-compatible wireless charging limit, and an integrated USB-C lanyard cable. Stock is sold out on the BMX site but should reach Amazon US in January.
