BMX SolidSafe 10K review: durable solid-state power bank, but heavier and pricier

The BMX SolidSafe 10K uses a solid-state battery that replaces flammable liquid electrolytes with a safer design; the reviewer notes a screwdriver driven into a fully charged pack produced only a whiff of smoke and no fire. Solid-state cells also promise a longer lifespan—around 1,000 recharge cycles versus roughly 500 for typical lithium-ion—and better performance in cold weather, including the ability to recharge at lower temperatures.

This 10,000mAh/38Wh power bank measures 4.0 x 2.7 x 0.6 inches and weighs 7.4 ounces. Its anodized aluminum and polymer shell gives it noticeable heft, and strong magnets hold the unit in place for wireless charging. The Qi2 pad can deliver up to 15W, and the device includes two USB-C ports with pass-through charging, supporting a maximum 30W output and 27W input.

A color display shows power levels and charging/discharging power, while a lanyard doubles as a USB-C-to-USB-C cable kept secure by a durable retainer clip.
