Next-Generation Disaster Preparedness Battery Launched: Eliminating “Charging Anxiety”
LAMA brand has released a multi-functional mobile battery designed to address the growing need for emergency power during disasters. This innovative device combines solar charging, hand-crank generation, wireless charging, and the ability to charge up to six devices simultaneously, offering a comprehensive solution for power outages, earthquakes, and heavy rains.
In recent years, Japan has faced increasing challenges from natural disasters such as earthquakes, typhoons, and linear rainbands, making disaster preparedness a daily concern. A critical aspect of this preparedness is ensuring smartphones remain charged. During emergencies, smartphones serve as vital lifelines for contacting family, accessing evacuation information, receiving government notifications, and even functioning as flashlights, payment methods, and maps. The fear of smartphone battery depletion during prolonged power outages, leading to a loss of information and communication, is a significant source of anxiety. This new product aims to alleviate such concerns.

The Rise of “Phase-Free” Disaster Preparedness
Traditional disaster preparedness items often suffer from issues such as being stored away and forgotten, being uncharged when needed, or users forgetting how to operate them. A growing trend is “phase-free disaster preparedness,” which emphasizes items that can be used routinely and seamlessly transition into emergency use. This new mobile battery embodies this concept, serving as an everyday portable charger while readily becoming an essential emergency power source during disasters.
