The TP4056 Lithium Battery Charger & Adjustable DC-DC Boost Converter Module is a highly compact, 2-in-1 power management board designed for DIY electronics, portable gadgets, and mini-UPS applications. It features an integrated USB Type-C interface to charge a single-cell 3.7V/4.2V lithium-ion or Li-Po battery safely while simultaneously boosting the output voltage up to 27V DC via an onboard adjustable potentiometer.
Core Capabilities
- Dual Functionality: Combines a safe 1A CC/CV linear lithium battery charger with a high-efficiency DC-DC step-up circuit on a single PCB.
- Adjustable Output Range: Smoothly steps up a 3.7V battery voltage to any targeted level between 4.3V and 27V DC to power microcontrollers, sensors, or 12V routers.
- Modern Type-C Port: Accepts standard 5V mobile charger inputs, backed by adjacent solder pads for direct hardwired power alternatives.
- Solder Terminal Layout: Includes clear, labeled pads for the battery source (
B+ / B-) and the regulated boosted load output (VO+ / VO-).
Are you planning to run this module at 5V, 9V, or 12V for your load? I can provide the exact maximum current limitations for that specific voltage range.
