1. This module uses an imported chip, and the output current is raised to 1A, which reduces the starting current and improves the reliability of the whole. 2. The product uses the patch inductor, the volume is super small, specially designed for the customer which the volume has the request 3. With the function of undervoltage indicator light, when the voltage is full, the light is light. When the voltage is lower than 2.7V, the lamp is extinguished. At this time, the battery should be charged to avoid damage to the battery.
