3.7V 9V 12V Type-C Lithium Battery Charger/Discharger Booster/Regulator Module Boost Step Up Module UPS Power Supply

Building a Battery-Powered Project and Struggling to Get the Voltage Right?

Anyone who works with lithium batteries — whether for DIY electronics, portable power banks, solar storage, or custom battery packs — knows the frustration of voltage mismatch. Your battery outputs 3.7V but your circuit needs 9V or 12V. You need a charger that works with Type-C but also handles the discharge and regulation side. You need a module that's compact enough to fit inside a project enclosure but capable enough to handle real-world power demands. Finding all of that in a single, reliable module is harder than it should be.

Charge. Discharge. Boost. Regulate. One Module.

This 3.7V–12V Type-C Lithium Battery Charger/Discharger Booster/Regulator Module is a multi-function power management module designed for lithium battery projects that need flexible voltage handling. It combines Type-C charging input, boost step-up conversion (from 3.7V up to 9V or 12V output), discharge management, and voltage regulation in a single compact module — making it the versatile power solution for DIY electronics, portable devices, UPS systems, and custom battery builds.

The Type-C input means it charges from any modern USB-C power source — phone chargers, laptop chargers, power banks — without needing a proprietary cable or dedicated charger. The boost step-up circuit converts the lithium cell's native 3.7V output to the higher voltages that many circuits and devices require, while the regulation circuitry ensures stable, clean output that won't damage sensitive electronics.

Why Makers and Engineers Choose This Module

• Multi-voltage output — boosts from 3.7V lithium cell voltage to 9V or 12V output; covers the most common project voltage requirements in a single module
• Type-C charging input — charges from any USB-C source; no proprietary cables, no dedicated charger required
• Boost step-up circuit — efficient voltage conversion from lithium cell voltage to higher output; suitable for powering 9V and 12V circuits from a single lithium cell
• Discharge management — controlled discharge prevents over-discharge damage to the lithium cell; extends battery life and protects the cell
• Voltage regulation — stable, clean output voltage that won't fluctuate under load; safe for sensitive electronics
• UPS power supply function — can be used as an uninterruptible power supply for small electronics; maintains power during mains interruptions
• Compact module format — small enough to integrate into project enclosures, custom battery packs, and portable devices
• Versatile applications — suitable for DIY electronics, portable power banks, solar battery storage, custom battery packs, and UPS systems

The Experience of Using It

You're building a portable 12V device powered by a single lithium cell. You wire in the module, connect your Type-C charger, and the cell charges cleanly. You connect your 12V circuit to the output and the boost converter delivers stable 12V — no fluctuation, no noise, no over-discharge risk. The module handles everything: charging, boosting, regulating, and protecting the cell. Your project works exactly as designed, powered reliably from a single lithium cell and a USB-C cable.

That's what a properly designed power management module delivers: the flexibility to build what you want, powered the way you need.
