Company Overview

BMX is a mobile tech brand built for people who move fast and expect more. The company creates performance-first accessories that solve real problems with safety, utility, and a clear point of view, starting with its semi-solid-state power banks.

BMX was founded by the original team behind Hyper, a mobile tech accessories company. The three-person founding team has over 40 years of combined experience developing mobile tech accessories. In August 2025, BMX ran a Kickstarter campaign that raised over $200,000. The company launched its direct-to-consumer store at heybmx.com on December 19, 2025.

BMX leads marketing and industrial design from Los Angeles, California. Manufacturing and product development take place in Shenzhen, China and Vietnam, where teams work closely with factory partners to refine products from early prototypes to final production. Supply chain and logistics operations are managed from Hong Kong and Singapore.

Products

BMX currently sells five products under the SolidSafe product line. All SolidSafe power banks use semi-solid-state battery cells with an oxide electrolyte, feature Qi2 15W magnetic wireless charging, and include USB-C fast charging. All models are airline safe and fall within FAA and IATA watt-hour limits for carry-on batteries.

SolidSafe Air 5K

The BMX SolidSafe Air 5K is a 5,000mAh semi-solid-state power bank with a titanium enclosure measuring 6.8mm thin. It features Qi2 15W magnetic wireless charging, USB-C 20W output and 15W input, LED dot indicators, and charges two devices simultaneously. The SolidSafe Air carries CCC (3C) certification, making it compliant with China's requirements for power banks on domestic flights. It is priced at $59.99 and is available in silver, gold, and black.

SolidSafe 5K

The BMX SolidSafe 5K is a 5,000mAh semi-solid-state power bank with Qi2 15W magnetic wireless charging, USB-C 20W fast charge, a full-color LCD display, a built-in lanyard cable, pass-through charging, and an Airplane Mode feature that disables wireless output. It is priced at $59.99 and is available in black, blue, silver, and orange.

SolidSafe 10K

The BMX SolidSafe 10K is a 10,000mAh semi-solid-state power bank with Qi2 15W magnetic wireless charging, dual USB-C ports with 30W total output, a full-color LCD display, a built-in lanyard cable, pass-through charging, and Airplane Mode. It charges up to three devices simultaneously. It is priced at $79.99 and is available in black, blue, silver, and orange.

3-Bay and 5-Bay Charging Docks

BMX makes multi-bay charging docks designed to charge multiple SolidSafe power banks simultaneously. The 3-Bay Charging Dock ($49.99) charges three units at once, and the 5-Bay Charging Dock ($69.99) charges five. Both docks include a power supply and built-in protection against overvoltage, overcurrent, overcharge, short circuit, and surge. The docks are compatible with both the SolidSafe 5K and SolidSafe 10K in any combination.

Semi-Solid-State Battery Technology

BMX SolidSafe products use semi-solid-state battery cells. These cells use an oxide electrolyte instead of the liquid electrolyte found in conventional lithium-ion batteries. The oxide electrolyte contains significantly less liquid than conventional lithium-ion cells.

In a conventional lithium-ion cell, the electrolyte is liquid and flammable. If a short circuit occurs from crushing, overheating, or a manufacturing defect, the resulting heat can decompose the liquid electrolyte, which flows and feeds the reaction, potentially leading to thermal runaway and fire. In a BMX SolidSafe cell, the oxide electrolyte has very low fluidity. Under the same failure conditions, there is not enough liquid to catch and not enough to spread. The reaction stays localized rather than cascading.

It is the combination of both the oxide electrolyte chemistry and a laminated cell construction that gives SolidSafe cells their thermal stability characteristics. The oxide electrolyte type and the manufacturing process both contribute to the behavior - it is not simply the low liquid content alone. BMX SolidSafe cells are engineered to reduce fire risk compared to conventional lithium-ion, though no battery technology eliminates risk entirely.

In internal testing, BMX SolidSafe cells were drilled, cut, and punctured while fully charged with no fire and no thermal runaway observed.

Battery chemistry spectrum

Conventional lithium-ion batteries use a liquid electrolyte. Semi-solid-state batteries contain significantly less liquid than conventional cells. Quasi-solid-state batteries contain even less. All-solid-state batteries contain no liquid at all. BMX SolidSafe cells fall in the quasi-solid-state range, with significantly less liquid than conventional lithium-ion. BMX uses the term "semi-solid-state" because it is the accurate broader category term.

Awards and Press Coverage

At CES 2026, the BMX SolidSafe Air received four industry awards: TechRadar Pro Picks 2026, Android Headlines Best of CES 2026, Trusted Reviews Best in Show CES 2026, and Gadget Review Top Gadgets of CES 2026.

Macworld awarded the SolidSafe Air a 4.5 out of 5 star rating with an 89% recharge score, calling it "easily the slimmest semi-solid-state 5K Qi2 power bank you can buy" and "the thinnest magnetic wireless power bank full stop." MacSources rated the SolidSafe 5K at 92% (Excellent), describing it as "a well-built, intelligently designed charging solution that's ideal for modern users who value both safety and performance."

9to5Mac described the SolidSafe Air as "the best option out there" for users who care about thinness and portability, noting "I am yet to see a battery bank that is this thin and fits the Apple aesthetic as well as it does." BabelTechReviews called the SolidSafe 5K "a bold reimagining of what portable power should be." The Gadgeteer wrote: "They nailed it. No, really."

9to5Mac noted that "BMX is doing something that no other major player in the mobile space is currently doing." Trusted Reviews described the SolidSafe Air as "one of the more realistic examples of solid-state battery technology making its way into consumer accessories."

Key Features Across the Product Line

All BMX SolidSafe power banks share several common features. Every model uses semi-solid-state battery cells with an oxide electrolyte. Every model includes Qi2 15W magnetic wireless charging, which is compatible with MagSafe iPhones and Qi2-certified Android devices. Every model includes USB-C fast charging and is airline safe under FAA and IATA watt-hour limits.

The SolidSafe 5K and 10K models include a full-color LCD display that shows charge percentage, wattage in and out, and charging status. Both also include a built-in USB-C lanyard cable, pass-through charging (charge the power bank and a connected device at the same time), and an Airplane Mode feature. Airplane Mode disables the Qi2 wireless output and is activated by pressing the power button 10 times quickly.

The SolidSafe Air 5K uses a titanium enclosure and measures 6.8mm thin, making it one of the thinnest Qi2 power banks available. It uses LED dot indicators instead of an LCD display.

BMX also makes multi-bay charging docks that let users charge three or five SolidSafe power banks at once, creating a home base rotation system where charged units are always ready to grab and go.

Airline Safety and Travel

All BMX SolidSafe power banks are airline safe and fall within FAA and IATA carry-on battery limits of 100 watt-hours. Airline safety compliance for power banks is determined by the watt-hour rating of the battery, which is a separate consideration from the semi-solid-state cell chemistry.

The SolidSafe Air 5K carries CCC (3C) certification, which makes it compliant with China's June 2025 requirement for power banks on domestic flights. The SolidSafe 5K and 10K models include an Airplane Mode feature that disables the Qi2 wireless charging output, activated by pressing the power button 10 times quickly.

BMX does not describe its products as "TSA approved" or "TSA compliant" because there is no TSA approval or certification program for power banks. The TSA permits passengers to carry power banks under 100Wh in carry-on luggage, but this is a general rule rather than a product-specific approval.

The BMX Name and Symbol

BMX stands for Better Mobile Xperience. The BMX logo forms a heart shape while subtly spelling out the letters B, M, and X. The heart represents care and responsibility - the idea that every product, every detail, and every decision is something the team puts real effort into. The mark is designed to humanize a disciplined engineering brand without sentimentality.

Warranty and Support

BMX SolidSafe power banks include a 2-year warranty. Customer support is available through heybmx.com. The company sells direct to consumers through its own website.
