【Mobile Battery Fire Hazard】A protective charm for train and airplane carry-on! A fireproof pouch to take along

Mobile batteries are essential in modern life, but many models contain lithium-ion batteries, which always carry the risk of unexpected ignition due to shock or degradation. The "Fireproof Pouch" was developed to protect homes, vehicles, and loved ones from such unforeseen circumstances.

A sturdy 4-layer structure using fiberglass blocks fire and heat

The biggest feature of this pouch lies in its unique 4-layer structure made from carefully selected flame-retardant materials.

By sandwiching two sheets of fiberglass between the outer fabric and the lining, the design suppresses the rapid spread of flames and heat to the outside even when ignition occurs inside. In actual fire resistance tests conducted by the manufacturer, it has reportedly demonstrated high heat insulation and fire resistance performance by not allowing flames to spread to the opposite side even after being exposed to flames over 1200 degrees for more than a minute.

It is expected to significantly reduce the fire risk during storage in bags, cars, and at home.

An optimal balance of compact size and convenience for everyday use

While it boasts high safety standards, it is also attractive for its design that does not compromise daily convenience. The dimensions, approximately 20cm in width and 12.5cm in height, are perfect for storing general mobile batteries and cables together, and by utilizing the included strap, transportation can be done smoothly.

Weighing about 73g, it is lightweight, allowing it to be used regularly as a gadget pouch without worrying about the weight, and it enables the natural incorporation of disaster preparedness into one's lifestyle.

Understanding the properties of fiberglass and the purpose of “delay in flame spread” is necessary.

On the other hand, there are points to be cautious about due to the materials prioritized for fire resistance. Generally, fiberglass can cause a prickly irritation when it comes in contact with the skin, so those with sensitive skin should avoid prolonged contact with bare hands and handle it with care.

Additionally, it is meant to “delay the spread of flames” and cannot completely contain the intense smoke or gas that can occur when lithium-ion batteries undergo thermal runaway. In case of an emergency, it is crucial to not over-rely on the pouch and to swiftly move away from the vicinity, combining it with basic fire prevention measures to ensure safety.
