IP2312 USB C 3A Fast Charging Module

Charge your lithium battery projects safely and quickly with this IP2312 USB-C Fast Charging Module, a compact charger board built around the IP2312 control chip for efficient, well-regulated single-cell lithium charging. With a modern USB Type-C input, this module accepts power from any standard USB-C charger or power bank, delivering up to 3A of fast charging current to your connected battery.

The module runs a full CC/CV (constant current, constant voltage) charging cycle, automatically switching modes as the battery charges to protect cell health and maximize charging speed. If the battery voltage drops below 3V, the board automatically enters a gentle trickle-charge mode at 100mA to safely recover a deeply discharged cell before switching to full-speed charging. Onboard LED indicators show charging status at a glance, a red LED while charging and a blue LED once the battery reaches full charge. Simple B+/B- solder pads make connecting your battery straightforward, and the board is a direct drop-in for 3.7V polymer ternary lithium and standard Li-ion cells.

This charging module is a practical building block for hobbyists and makers building custom power banks, battery packs, portable devices, and other DIY electronics that need reliable single-cell lithium charging. Note that it is not suitable for 3.2V LiFePO4 batteries, which require a different charge profile.
