Compact design: measures 5 mm x 14.5 mm x 4.2 mm and is the size of a cent coin, making it suitable for ultrathin modules, tight spaces, and portable applications. Stable charging current: delivers a steady 1 A throughout the charging process, enabling efficient battery charging without the need for additional heat dissipation and reducing overall heat generation. Wide compatibility: compatible with both lithiumion and lithium iron phosphate (LiFePO4) batteries; adapts to your specific battery needs with a simple setting change. Heat protection feature: equipped with overheating protection; automatically reduces current to safe levels to prevent damage and ensure safe operation during prolonged use. Use scenarios: Ultrathin battery packs in wearables, compact consumer electronics, or other spaceconstrained devices. Portable power banks and slim battery packs for cameras, drones, or handheld gadgets. Remote sensing equipment or compact RC devices where space is limited and reliable charging is required.
