Type-C 15W 3A 18650 Lithium Battery Charger Module DC-DC Step Up Booster 3.7V To 12V Fast Charge UPS Power Supply Converter 12V شحن و تفريغ و رافع جهد

The Type-C 15W 3A 18650 Lithium Battery Charger Module is a compact, multifunction power module designed to charge and discharge a single 18650 lithium cell while providing a DC-DC step-up boost to 12V output. It accepts a Type-C input and implements fast charge capabilities at up to 15W and 3A, enabling efficient replenishment of a 3.7V nominal lithium cell and simultaneous use as a small UPS or portable 12V power source. The module supports controlled charge and discharge operations and integrates functions commonly required for battery-based power conversion and backup applications.Key practical uses include serving as a bench-level 12V boost converter from a single 18650 cell, a compact UPS for low-power electronics, and a development component for battery-powered designs where Type-C convenience and a regulated 12V rail are needed. The board is suitable for integration into prototypes, repair projects, and custom power solutions where space is limited and a single lithium cell is preferred.Installation notes: observe correct polarity when connecting the 18650 cell, follow safe charging and handling practices for lithium batteries, and ensure load current and heat dissipation are compatible with the module's rated 15W/3A operating envelope. For reliable operation, use a quality Type-C power source and avoid exposing the module or cell to mechanical damage, extreme temperatures, or moisture. This module provides a practical, compact building block for charging and boosting a 3.7V 18650 cell to deliver regulated 12V output for small equipment and backup power scenarios.
