Description

The Guangdong QINX 12.6V 4A Li-ion battery charger is engineered for 3-cell lithium-ion battery systems used in a wide range of portable and embedded electronic products. The 4A output provides significantly faster charging performance while maintaining stable thermal control and high charging accuracy.

This charger adopts an intelligent CC/CV charging profile optimized for lithium-ion chemistry. It ensures consistent current delivery during the bulk charging phase and precise voltage regulation during the final charging stage, effectively preventing overcharging and extending overall battery lifespan.

With a universal 100–240VAC input design, the charger is suitable for global applications without additional voltage conversion devices. It is widely used by OEM manufacturers requiring standardized and reliable charging solutions for mass production.

Compared with lower-current versions, the 4A model is better suited for medium-capacity battery packs where charging efficiency and reduced downtime are important. Guangdong QINX supports full customization including connector types, cable length, housing design, branding, and packaging solutions to meet different project requirements.
