MICRODIA Launches Domestic Proposal for 'SNAPPower 3S TRON', a Semi-Solid-State Battery Power Bank Capable of Charging Apple Watch and AirPods Simultaneously

We are introducing a next-generation mobile battery that consolidates charging environments for users who daily carry smartphones, Apple Watch, and AirPods.

Kofuku Shoji G.K. (Headquarters: Arakawa-ku, Tokyo), as the sole distributor for the US-based mobile accessory brand 'MICRODIA' in Japan, is beginning domestic proposals for the 'SNAPPower 3S TRON' series, a 3-in-1 wireless magnetic power bank utilizing semi-solid-state batteries.

This product is a next-generation mobile battery capable of charging wireless charging devices such as smartphones, Apple Watch, and AirPods all in one unit.

It supports a maximum output of 45W, featuring Qi2.2 25W wireless charging, USB-C PD output, magnetic charging for MagSafe-compatible smartphones, Apple Watch charging, and AirPods charging.

Furthermore, the unit is equipped with a TFT smart display, allowing users to visually check battery level, temperature, output, and charge cycles.

By enhancing safety, fast charging, portability, and design, we are moving forward with proposals for retailers, corporations, e-commerce operators, and campaign operators.

## Charging Smartphones, Apple Watch, and AirPods in One Device

In recent years, the number of devices requiring daily charging—including smartphones, Apple Watch, wireless earphones, tablets, and USB-C compatible devices—continues to grow.

On the other hand, carrying multiple chargers and cables when traveling or away from home has become a burden for users.

To address these challenges, the SNAPPower 3S TRON employs a 3-in-1 structure capable of charging smartphones, Apple Watch, and AirPods with a single device.

Smartphones can be charged via magnetic wireless charging, and the Apple Watch can be charged in a dedicated section. Additionally, since wireless earphones like AirPods can also be charged, it simplifies the charging environment when away.

## Safety-Focused Design Adopting Semi-Solid-State Batteries

The SNAPPower 3S TRON is a mobile battery that adopts semi-solid-state batteries.

Semi-solid-state batteries are a next-generation technology expected to offer improved stability and safety compared to conventional lithium-ion batteries.

This product, with its semi-solid-state design prioritizing 100% airline-friendly characteristics and high safety, is suitable not only for daily use but also for scenarios involving frequent carrying, such as business trips, travel, events, and corporate use.

Furthermore, it is characterized by a design prioritizing robustness, aiming to maintain reliability even under extreme conditions such as drops, immersion, punctures, and fire exposure.

## Supports Maximum 45W Output

This product supports a maximum output of 45W.

The configuration is designed for a combination of 25W MagSafe/Qi2-series wireless charging and 20W USB-C PD output.

It is suitable for users who want to fast-charge not only their smartphones but also charge their Apple Watch, AirPods, and USB-C compatible devices simultaneously.

Moreover, with 45W output, it can accommodate a wide range of needs, such as short-time charging on the go, auxiliary power during business trips, and smartphone charging at event venues.

## Deploying Qi2.2 25W Compatible Models

SNAPPower 3S TRON features a lineup including Qi2.2 25W compatible models.

Qi2 is gaining attention as a standard that leverages magnetic alignment to enhance wireless charging stability.

By deploying Qi2.2 25W models in addition to Qi2 15W models, we increase our ability to propose solutions for upcoming compatible devices such as the iPhone 17 and Samsung smartphones.

It is a product that retailers can easily propose as a high-value accessory for the latest smartphones.

## Visualizing Charging Status with TFT Smart Display

The unit is equipped with a TFT smart display.

On the screen, users can check the following information:

- Battery Level
- Output Status
- USB-C Output
- Wireless Charging Output
- Temperature
- Charge Cycles
- Power Bank Status

It features the ability to visually check charging status, which was difficult to understand with conventional LED displays.

This makes it easier for users to understand the battery's condition and use it with peace of mind.

## Charging Control via SmartAI

This product incorporates MICRODIA's patented charging algorithm, 'SmartAI'.

'SmartAI' is a technology that controls charging status according to the connected device, aiming for fast and safe charging.

By combining this with protection functions against overcharge, overheat, and short circuits, it provides a smart charging experience.
