Portable power accessories are undergoing a materials shift as manufacturers look toward advanced chemistry to boost capacity without expanding physical dimensions. BMX has entered this space with the release of the SolidSafe 20K, a high-capacity portable charger that swaps traditional liquid electrolytes for a solid or gel alternative. Priced at $109.99, which translates to roughly £85 or AU$160, the new accessory is designed to provide safer, slower-degrading power for users carrying everything from smartphones to laptops.
The primary advantage of semi-solid-state architecture lies in safety and longevity. By replacing most of the liquid found in conventional lithium-ion power banks with a solid or gel electrolyte, the risk of flammability drops significantly. Furthermore, these cells resist degradation over time, meaning the device will maintain its health across significantly more charge cycles than older battery types. Despite packing a 20,000mAh capacity into a profile measuring 147.4 x 90.3 x 18mm and weighing 375g, the unit remains notably slim for a laptop-capable battery pack.
Key takeaways
- The BMX SolidSafe 20K features a 20,000mAh capacity and sells for $109.99.
- It utilizes semi-solid-state battery technology for increased safety and slower degradation.
- The power bank delivers up to 100W of output via its primary USB-C port.
- It includes a tiny color LCD screen displaying battery percentage and wattage per port.
Port versatility and performance
While many rival devices utilizing similar advanced chemistry remain restricted to smartphones and tablets, the SolidSafe 20K boasts enough output to comfortably fuel larger machines. BMX highlights that the battery pack is capable of delivering one full charge to a 13.6-inch MacBook Air M3, with residual power left over. To accommodate multiple devices simultaneously, the hardware is equipped with a total of three distinct output ports.
Users plugging a single device into the primary USB-C port will access the full 100W charging speed. A secondary USB-C port handles up to 65W independently, while a standard USB-A port maxes out at 22.5W. When all three connectors are occupied at the same time, the power allocation shifts to 65W on the primary port and 7.5W distributed across the other two connections. Real-time metrics are visible through a tiny color LCD screen built into the housing, which explicitly displays the remaining battery percentage alongside the active wattage on each individual port.
Availability and travel readiness
Weighing in at 375g and engineered with a slim construction, the battery pack is positioned as an ideal travel companion. It safely falls under the standard 100W carry-on regulatory limit enforced by most airlines for spare lithium-based batteries, allowing travelers to pack it in their cabin luggage without complications.
At present, the SolidSafe 20K is officially available for purchase within the United States for $109.99. BMX has not yet announced a confirmed release date or pricing for the United Kingdom or Australia, though the company maintains a commercial presence in both regions, suggesting an international rollout could follow in the future.
