This module uses linear charging for a single 18650 lithium-ion cell, making it a practical choice for hobby electronics, RC builds, portable lighting rigs, and custom devices. It turns battery charging into a cleaner part of the build instead of an extra problem to solve.

The clear LED indicators make it easy to see when the cell is charging and when it is full. That saves time during setup and testing, especially when the charger sits inside a small enclosure or a finished project.

Its range of USB input options gives you more freedom when matching the charger to your existing cables and power sources. The compact board layout also keeps your build organized, which matters when space is tight and neat wiring counts.

With built-in protection circuitry and a simple connection path, this module brings more control to your power setup without adding unnecessary complexity.

Make single-cell charging easier and keep your projects powered with more confidence.
