Key Features

Semi-Solid Battery Technology for Enhanced Safety

The SSA5K incorporates semi-solid battery technology, which is designed to suppress thermal runaway and ignition risks compared to conventional lithium-ion batteries. This structure enhances internal stability, helping to reduce heat generation even in high-temperature environments or during prolonged use, ensuring safer operation. Furthermore, its robust design offers increased resistance to external impacts and pressure, mitigating the risk of issues during daily carrying and usage. This design makes the mobile battery particularly suitable for use in warmer seasons, extended outings, or travel.

Safety verification tests, including those under pressure, load, nail penetration, drop, and high-temperature conditions, have been conducted. More details can be found on the product page: https://suneast.co.jp/suneast/semi_solid_mobile_battery-power_bank_ssa5k/

Ultra-Thin and Lightweight Design (Approximately 7.2mm)

With an ultra-slim profile of approximately 7.2mm and a weight of about 110g, the SSA5K is designed for easy portability, fitting neatly into pockets or bags. It ranks among the thinnest mobile batteries currently available.

Ultra-Thin and Lightweight Design

Qi2 Wireless Charging (Up to 15W)

The battery supports Qi2 wireless charging, allowing devices to be securely attached magnetically for stable charging. This feature provides a convenient, cable-free charging experience.

Qi2 Wireless Charging

Wired Max 20W Output & Pass-Through Charging

The SSA5K offers a maximum wired output of 20W. Additionally, it supports pass-through charging, enabling users to charge the power bank itself while simultaneously providing magnetic wireless power (Qi2) to a smartphone. This combination of wired and wireless charging ensures an efficient and streamlined charging environment.

Pass-Through Charging

Simultaneous 2-Device Charging

Capable of simultaneous wireless and wired charging, the SSA5K can power multiple devices, such as a smartphone and earphones, concurrently. This allows for efficient device management, even when on the go.

Simultaneous 2-Device Charging

4-Stage LED Battery Level Indicator

A clear 4-stage LED indicator provides a visual representation of the battery’s remaining charge, allowing users to intuitively know when recharging is needed.
