TL;DR BMX is bringing solid-state tech to battery packs with a 5,000mAh and 10,000mAh solution.
Solid-state construction allows these batteries to take serious damage and keep right on running.
Magnetic Qi charging also makes them perfect for pairing with a new Pixel 10.
Lithium-ion batteries have been an utter game-changer for mobile devices, making possible everything from our smartphones to practical electric cars. But for all the power they can offer, their construction comes at a perilous disadvantage: It’s far too easy to damage one, and that risks the battery becoming a serious fire hazard.
One of the best solutions we’ve come up with for fixing that problem is replacing the liquid electrolyte that mobilizes the charge in these cells with a mostly solid alternative: so-called solid-state batteries. Not only does that kind of design improve power density (so smaller batteries can hold more charge), but it also wildly improves durability — and resistance to catastrophic failure.

This year at IFA 2025, BMX is showing off its latest mobile accessories, including its new SolidSafe Solid-State Magnetic Power Banks, and I had the chance to check out just how resilient these solid-state batteries are in the face of even aggressive damage.
BMX is launching its solid-state lineup two different capacities — both 5,000mAh and 10,000mAh solutions — with an upgraded 10K model even offering extra storage via microSD. But while battery packs this size are basically commodities by now, precious few are built around solid-state cells that can take a beating without even blinking.
