Description

The Guangdong QINX 12.6V 3.5A Li-ion battery charger is optimized for 3-cell lithium-ion battery systems widely used in portable electronics and embedded power solutions. The 3.5A output delivers a moderate-fast charging experience while maintaining excellent thermal stability and electrical safety.

This charger is built with an intelligent CC/CV charging algorithm specifically tailored for lithium-ion chemistry. It ensures consistent current output during the bulk charging stage and precise voltage regulation during the final stage, effectively preventing overcharging and enhancing overall battery durability.

With a universal 100–240VAC input range, the charger is suitable for global applications without additional power conversion equipment. It is widely used in OEM manufacturing environments where stable and standardized charging solutions are required for mass production.

Compared with lower-current models, this 3.5A version offers improved charging efficiency while still maintaining controlled heat output, making it suitable for medium-capacity battery packs. Guangdong QINX provides full customization options including connector types, cable length, housing design, branding, and packaging solutions.
