MICRODIA Introduces SNAPPower 3S TRON Semi-Solid-State Power Bank for Simultaneous Charging of Apple Watch and AirPods in Japan
Kofuku Shoji LLC, the Japan general agent for the U.S.-based mobile accessory brand “MICRODIA,” has begun domestic proposals for the “SNAPPower 3S TRON” series. This 3-in-1 wireless magnetic power bank, featuring a semi-solid-state battery, is designed to meet the charging needs of users who regularly carry smartphones, Apple Watch, and AirPods.
All-in-One Charging for Smartphones, Apple Watch, and AirPods
As the number of daily-use devices requiring charging continues to grow, carrying multiple chargers and cables can be a burden. The SNAPPower 3S TRON addresses this by offering a 3-in-1 structure capable of charging smartphones, Apple Watch, and AirPods from a single unit.
Smartphones can be charged via magnetic wireless charging, while the Apple Watch has a dedicated charging area. Additionally, wireless earphones like AirPods can also be charged, simplifying the charging setup for users on the go.

Safety-Focused Design with Semi-Solid-State Battery
Safety is a paramount concern for portable power solutions. The SNAPPower 3S TRON incorporates a semi-solid-state battery, a next-generation battery technology that offers enhanced stability and safety compared to conventional lithium-ion batteries.
This design ensures the product is 100% airline-friendly and suitable for various scenarios, including daily use, business trips, travel, and corporate applications. The robust construction is engineered to maintain reliability even under extreme conditions such as drops, water immersion, punctures, and exposure to fire.

Supports Up to 45W Output
The SNAPPower 3S TRON delivers a maximum output of 45W. This includes a combination of 25W MagSafe/Qi2-compatible wireless charging and 20W USB-C PD output. This capability makes it suitable for rapid smartphone charging and simultaneously powering Apple Watch, AirPods, and other USB-C compatible devices.
With 45W output, the power bank can support various uses, such as quick charges during short outings, auxiliary power during business trips, and phone charging at event venues.

Qi2.2 25W Compatible Models Available
The SNAPPower 3S TRON series includes models compatible with Qi2.2 25W. Qi2 is an emerging standard that enhances wireless charging stability through magnetic alignment. By offering Qi2.2 25W compatible models alongside Qi2 15W models, the series aims to provide advanced charging solutions for future devices such as iPhone 17 and Samsung smartphones.
TFT Smart Display for Visible Charging Status
The device is equipped with a TFT smart display, providing visual confirmation of various charging states. Users can easily check the following information:
-
Battery level
-
Output status (USB-C and wireless charging output)
-
Temperature
-
Charging cycles
-
Power bank status
This visual interface offers a clearer understanding of the battery’s condition compared to traditional LED indicators, enhancing user confidence and convenience.

SmartAI for Charging Control
MICRODIA’s patented charging algorithm, “SmartAI,” is integrated into the SNAPPower 3S TRON. SmartAI intelligently controls the charging process based on the connected device, aiming for fast and safe charging.
Combined with protection features against overcharging, overheating, and short circuits, SmartAI contributes to a charging experience that also considers the battery life of smartphones and peripheral devices.

Premium-Grade Aluminum Frame
The SNAPPower 3S TRON features an aircraft-grade aluminum frame. This design not only enhances strength but also contributes to efficient heat dissipation. The smooth matte surface provides a premium tactile feel and sophisticated appearance, making it a stylish accessory to carry alongside a smartphone.


Available in 5000mAh and 10000mAh, Three Colors
The series is planned to include 5000mAh and 10000mAh models. Color options are expected to include Charcoal, Pearl White, and Orange. The 5000mAh model is suitable for users seeking a compact and lightweight option, while the 10000mAh model is ideal for extended outings, travel, and business trips.
