15W 3A DC‑DC 12V Fast Charging Module for 18650 Lithium Battery, Type‑C

Product Description

POWER SWITCHING – This fast‑charging lithium battery module is equipped with a UPS circuit that allows seamless switching between the power supply and the battery without any delay.

UPS Power Supply – The uninterruptible power supply (UPS) function ensures that when external power is available, it directly provides charging through the boost circuit while charging the lithium battery.

LED Indicator – The dual‑color LED indicator displays the charging status: the green light stays on when the battery is fully charged and the charging process stops automatically.

Good Protection – With automatic activation of the battery path and restoration of power to the load after startup, this module provides protection against short circuits, overvoltage, and undervoltage.
