24M to Expand Its Product Portfolio, Introduce New Power Bank with Breakthrough Safety Controls and Energy Performance
First Commercial Consumer Device from Renowned Battery Technology Pioneer Set to Redefine Battery Safety and Bolster Consumer Confidence
Cambridge, Mass., September 24, 2025 — 24M Technologies, recognized globally as a pioneer in battery technologies, today announced it is expanding its innovation and product portfolio with the launch of a new flagship 24M power bank that will redefine industry standards for safety, reliability, and performance. Utilizing 24M’s revolutionary Impervio™ separator and Eternalyte™ electrolyte, this new portable charger marks the company’s first commercially available product for the consumer electronics market. Initial products are undergoing stringent testing and certification, and commercial availability is expected in the first half of 2026.
“Consumers should not have to choose between safety and performance,” said Naoki Ota, president and CEO of 24M. “We’ve seen far too many fire incidents involving power banks and felt a great responsibility to show the world there is a safer yet still incredibly powerful path for electrification. The 24M power bank has been designed to combine rigorous safety controls with state-of-the-art energy technology to create a power solution users can trust anywhere and at any time – whether charging a phone, laptop, or other device.”
Power banks, while convenient and common, carry serious risks as evidenced by an increase of fire incidents on planes, in homes and other locations. In relying on lithium-ion batteries to deliver energy, a single battery defect such as an impurity or manufacturing flaw can create an internal short circuit and trigger overheating, device swelling, or thermal runaway, leading to smoke, fire, or even explosion. The dangers from these devices are amplified by uncertified or low-quality products, improper charging practices, and storage in confined, hot environments. In addition, as new applications and the use of AI increase, demand for power banks with greater power and faster charging grows, and so too does the need for robust safety technologies and rigorous testing.
The new 24M power bank features two of the company’s most groundbreaking innovations — Impervio and Eternalyte — that set new standards for safety and performance. Impervio is a transformative separator that prevents catastrophic battery fires and continuously monitors battery state of health to prevent a fire before it occurs. Eternalyte is a premier battery electrolyte that enables rapid charging and eliminates power loss in cold temperatures. Together, these two innovations are used in tandem to create a device that delivers unprecedented safety without sacrificing performance.
With the growing concerns for overheating, battery degradation, and fire risks in existing power banks, the 24M device introduces a multi-layer safety architecture and advanced energy system to deliver robust power and peace of mind. A core innovation, enabled by the Impervio separator, is a button for “Airplane” and “Disposal” modes that will bring the 24M power bank to a safe capacity before boarding a flight or a safe stage to responsibly dispose the product.
