Safer Power Banks Hit Market With Fire-Resistant Tech

Your phone's backup battery just got a major safety upgrade that could prevent the kind of fires that have plagued lithium batteries for years.

Singapore-based BMX has released its SolidSafe power bank lineup, featuring semi-solid-state battery technology that slashes the amount of flammable liquid inside each cell. The devices went on sale this week through Amazon and the company's website, with prices starting at $59.

Traditional power banks use lithium-ion batteries filled with liquid electrolyte to transfer energy between electrodes. That liquid is highly flammable and can cause fires if the battery overheats, gets damaged, or swells from age.

Semi-solid-state batteries flip that script by replacing most of the flammable liquid with safer materials. The result is a power bank that stays stable even under extreme conditions and resists physical damage better than conventional batteries.

The lineup includes 5,000mAh and 10,000mAh models with magnetic Qi2 wireless charging and aluminum bodies. Both versions offer USB-C fast charging up to 30W and real-time charging displays.

The standout product is the SolidSafe Air, which BMX calls the world's thinnest semi-solid-state wireless power bank. At just 6.8mm thick, it's slim enough for easy travel while packing 5,000mAh of capacity, 15W wireless charging, and a titanium-reinforced frame.

The larger models include thoughtful extras like built-in USB-C cables attached via lanyard and color displays showing charge levels. One version even adds a microSD card slot for portable storage alongside your portable power.

BMX first showed these power banks at CES 2025 in January. Now consumers can actually buy the technology that experts have been calling the next evolution in battery safety.

The Bright Side

Battery fires have been a persistent concern as we carry more devices. Airlines restrict damaged batteries, and recalls happen regularly when power banks overheat or catch fire.

This new chemistry tackles the root cause rather than just adding more safety circuits. Reducing flammable materials inside the battery means fewer catastrophic failures, even if something goes wrong.

The technology also opens doors for safer batteries in everything from phones to electric vehicles as semi-solid-state designs continue improving. What starts as a better power bank today could become the standard for all our devices tomorrow.

For travelers especially, knowing your backup battery won't fail during a long flight brings real peace of mind. That's progress you can literally hold in your hand.
