I tested the thinnest Qi2 power bank on the market - and it's thanks to semi solid-state batteries

### Executive summary **ZDNET review — BMX SolidSafe Air:** A concise review of the thinnest 5,000 mAh Qi2 MagSafe-compatible power bank (6.8 mm thick, 4.1 oz) that highlights its 15W Qi2 wireless charging, single USB-C 15W input/output with pass-through charging, and a semi-solid-state 19.25 Wh battery touted as safer and more fire-resistant with ~1,000 recharge cycles; reviewer performed puncture testing, found minimal thermal reaction, and recommends it for safety-conscious users despite limited capacity (roughly one phone charge) and a $60 price point.
