Secure Power During Outages: Introducing the 4-Way Charging, 4-Panel Solar Mobile Battery
In recent years, Japan has experienced a series of natural disasters, including earthquakes, typhoons, and heavy rains, leading to increased public awareness of disaster preparedness. For instance, an earthquake with a maximum seismic intensity of 7 was observed in Kumamoto Prefecture on July 28, 2026, re-emphasizing the critical importance of being prepared for disasters and securing lifelines.
Smartphones, in particular, have become indispensable for gathering information and communicating with family during emergencies. This highlights the growing need for disaster preparedness that includes a reliable means to charge devices even during power outages.
Responding to this heightened disaster awareness, LAMA Store Rakuten (operated by L&L LivelyLife Co., Ltd.) has launched the “Solar Mobile Battery 20000mAh.” This device supports 4-way charging: solar, hand-crank, built-in cable, and Type-C connection. It is designed to be a portable emergency power source.

This multi-functional device features high-efficiency power generation from four solar panels, simultaneous charging for up to six devices, and an integrated LED light. It serves not only as an emergency power source during outages but also as a versatile item for daily use, such as during camping and hiking.

4 Solar Panels & 4-Way Charging: Next-Generation Battery Utilizing Natural Power
Equipped with four high-efficiency solar panels, this battery significantly improves charging efficiency compared to conventional models. It supports four charging methods—solar, hand-crank, built-in cable, and Type-C connection—allowing users to choose the most suitable method even in environments without a power outlet.
This makes it a reliable power source for outdoor activities like camping and hiking, as well as for emergencies such as earthquakes, typhoons, and power outages.


20000mAh Large Capacity & Up to 6 Devices Simultaneously: Secure Power for Families and Groups
With a large capacity of 20000mAh, the battery supports charging for multiple devices such as smartphones and tablets. It can charge up to six devices simultaneously, which is convenient for charging multiple family members’ devices during a disaster. This design ensures sufficient power for both daily use and emergencies.


Wireless Charging & Multi-Device Compatibility: Eliminating Cable Shortage Concerns
In addition to Qi-compatible wireless charging, the battery features multiple charging methods including built-in Lightning, Type-C, and USB cables. It supports a wide range of devices such as iPhones and Android phones, reducing the hassle of carrying multiple dedicated cables. This allows flexible charging of various devices both on the go and during disasters.


Max 800 Lumens LED Light: Multi-Functional Design for Disaster Preparedness
The main unit is equipped with a high-brightness LED light that supports three modes: normal illumination, flashlight, and SOS emergency signal. With a brightness of up to 800 lumens, it can be used for lighting during power outages, night-time evacuations, and as a light for outdoor activities. It functions not only as a charging device but also as a disaster light supporting safety during emergencies.

Waterproof, Durable & Compact: Wide Range of Use from Disaster Preparedness to Outdoor Activities
Designed with life waterproof, dustproof, and shock-resistant specifications, it can be used safely in outdoor environments. It comes with a carabiner and strap, making it easy to attach to bags or outdoor gear. This convenient item is suitable for various situations, including being kept in a disaster kit, camping, fishing, hiking, and traveling.

From “Preparing” to “Continuously Using” Disaster Preparedness
Recent disaster preparedness strategies increasingly focus on “phase-free” disaster supplies—items that can be used not only during emergencies but also in daily life and leisure. The “Solar Mobile Battery 20000mAh” is one such device that can be used as an outdoor or travel battery on a regular basis and as an emergency power source during disasters.
It provides a reliable power environment as a new disaster preparedness item that supports daily life while preparing for sudden power outages and natural disasters.
