This is a Lipo Charger-Type C that is specifically designed for a single-cell 3.7V lithium battery. Its compact size makes it easy to integrate into your applications. The charger makes use of the TP4056X lithium battery charging IC, which ensures safe and speedy charging. Additionally, you can easily switch between three output currents (with the default output current being 50mA) by selecting different bonding pads on the back. The thermal feedback mechanism inside the TP4056X automatically adjusts the charging current to limit the chip temperature under high power operation or high ambient temperature conditions.

To use the charger, plug it into a power source via its Type-C port. When no battery is connected, the LED on the charger will flash. When charging, the LED will stay on, and when the battery is fully charged, it will turn off. The LED will not consume any of your battery’s power. Moreover, you can connect an external indicator, which will allow you to effortlessly check the charging status when this module is integrated into your projects.

The charger has three charging stages: trickle charge, constant current charge, and constant voltage charge. These stages ensure safety and save charging time.

Note: The low-current mode can charge large-capacity batteries, but the high-current gear cannot charge small-capacity batteries. If the charging current is too large, it may cause a battery explosion.
