IP2312 3A Type-C Lithium Battery Charger Module 5V to 4.2V

The IP2312 3A Type-C Lithium Battery Charger Module is a high-efficiency, synchronous step-down (buck) charging board designed for standard 3.7V ternary lithium-ion and polymer batteries. Unlike traditional linear chargers like the TP4056, the IP2312 utilizes a switching buck topology to deliver up to 3A of charging current with significantly lower heat generation and higher conversion efficiency. This makes it an excellent choice for fast-charging high-capacity single-cell batteries safely and reliably.

This compact module features a modern USB Type-C input interface alongside dedicated solder pads for direct wire connections. It operates on a standard 5V input and outputs a precise 4.2V CV (Constant Voltage) threshold. It is highly compatible with standard 18650, 21700, and lithium-polymer (Li-Po) cells, making it perfect for DIY power banks, portable electronics, robotics, and IoT projects powered by microcontrollers like ESP32 or Arduino.

Features:

• High-Efficiency Buck Charging: Synchronous switching topology ensures up to 93% efficiency, keeping the module cool even at 3A.
• High Charging Current: Supports up to 3A continuous charging current for rapid battery replenishment.
• Type-C Input: Equipped with a robust USB Type-C port for easy integration with standard phone chargers and adapters.
• Complete Charge Management: Integrates trickle charge, constant current (CC), and constant voltage (CV) charging modes.
• Onboard LED Indicators: Features clear status LEDs to indicate charging (Red) and fully charged (Blue) states.
• Ultra-Compact Design: Weighing just 3.3 grams, it easily fits into space-constrained DIY enclosures and portable devices.

Package Includes:

1 x IP2312 3A Type-C Lithium Battery Charger Module (5V to 4.2V)
