Power Bank Core

People carry power banks everywhere. They get frustrated when the battery dies before their phone does. This power bank core solves that problem with a 5000mAh capacity and a nominal voltage of 3.85V. One full charge can refill most smartphones at least once. The cycle life reaches 800 cycles. The discharge temperature range is -20℃ to 50℃.

We started our battery business in 2014, giving us 12 years of manufacturing experience. Our Zhuhai facility covers 14,000 square meters. Two hundred thirty employees operate our production lines. Our engineering team previously supplied phone batteries to Siemens and Panasonic. Working with those brands taught us how to build long-lasting and reliable battery cells.

This power bank core includes four layers of protection against overcharging, over-discharging, over-current, and short circuits.

Power bank users often leave devices plugged in overnight, so safety matters. Our battery is designed to handle this safely and reliably.

The 5000mAh capacity matches the battery size used in many flagship smartphones. Even heavy users can stay powered throughout the day. The 800-cycle lifespan provides more than two years of daily charging use.
