Next-Generation Mobile Battery with Automatic Charging and Simultaneous Dual Device Support
This product is engineered to minimize the act of charging itself. By placing the mobile battery back onto its dedicated base, it automatically begins charging, ensuring the device remains charged as a natural part of daily life.
Addressing the Common Problem of “No Charge When Needed”
The widespread use of smartphones and wireless devices often leads to situations where users find themselves with insufficient battery power:
-
Realizing a low battery just before leaving home.
-
Uncertainty about remaining battery levels while in a bag.
-
Stress from forgetting to charge.
The “Sugoi Mobile Battery” tackles these issues with a system designed around the habit of “returning it to charge.”

Automatic Charging Base Eliminates the Need for Charge Management
The core concept is to integrate “automatic charging” into daily life through a simple cycle: “Take → Use → Return.”
The system ensures charging begins automatically when the battery is returned to its dedicated base, offering several benefits:
-
No need to consciously think about charging times.
-
A fixed storage location reduces the effort of searching for the battery.
-
Returning it after use ensures it’s ready for the next use.
This design allows for battery management as an extension of daily routines.

Five Innovations for Seamless Automatic Charging
- Mindful Charging Design: A simple process where charging starts by simply returning the battery, removing the need to plan charging times.
- Dedicated Storage Location: Establishing a specific place to return the battery reduces unnecessary actions like searching or wondering where to put it.
- Integrated Control Functions: Equipped with control functions that monitor temperature and output, the system stops operation before any abnormal conditions arise.
-
Optimized Capacity: A configuration of two 5000mAh units allows for flexible usage:
-
One unit for lighter days.
-
Both units for extended outings.
- Peace of Mind with Dual Units: Even if one unit is in use, the presence of another reduces anxiety about running out of charge.

Design that Blends into Daily Life
The design is conceived for natural integration into everyday spaces such as dining areas, desks, and counters. Available in a space-blending white and a subtly distinctive green, the color options are chosen to ensure the device feels natural when placed anywhere.

Safety-Conscious Design
Considerations for heat generation and usage safety have been incorporated through both material and circuit design:
-
Temperature monitoring function.
-
Output control function.
-
Various tests (overload, heat generation, durability) have been conducted.
The product is also compliant with the following certifications: PSE, CE, FCC, RoHS. It utilizes semi-solid cells with an aluminum laminate exterior.

Ideal for New Lifestyles and Travel Seasons
Spring often marks new beginnings and increased travel, making this product suitable for individuals starting new commutes or studies, traveling, or on long-distance business trips. It is designed for those who wish to streamline their charging environment while minimizing luggage.
