Continuous Power for Your Critical Electronics

Power outages and unstable connections can ruin hours of hard work or disable vital security equipment. The 18650 Lithium Battery Charger & DC-DC Booster Converter is engineered to eliminate power interruptions. By combining a high-efficiency boost circuit with intelligent UPS switching, this module ensures your devices stay online, automatically transitioning to battery power the millisecond the main Type-C input is cut off.

Engineered for Efficiency and Safety

Running high-drain devices requires stable, clean power. Equipped with a built-in 12A high-current MOS, this step-up board delivers a rated 15W (with peaks up to 20W) with an impressive 96% conversion efficiency. You are fully protected against the most common electrical faults. The onboard Battery Management System (BMS) actively guards against over-charging, over-discharging, over-temperature, and over-current scenarios, preserving the lifespan of your 18650 cells.

Customizable for Advanced Engineering

Flexibility is built into the design. Need to conserve every drop of power for a remote, off-grid IoT sensor? Simply desolder the output LED indicator to slash the static power consumption by over 10mA. Building a larger power bank? Easily wire multiple 18650 cells in parallel to scale your capacity without interfering with the UPS logic. Whether you are running a 5V microcomputer or a 12V CCTV camera, this compact module is the silent, reliable engine driving your project forward.
