Key Features
- All-in-One Design: Combines TP4056-based lithium charging circuit with a DC-DC boost converter on a single board - no need for separate modules.
- Micro-USB Charging Input: Plug in any standard 5V Micro-USB cable to charge the connected 18650 cell at up to 1A.
- Regulated 5V USB Output: Built-in boost converter steps up the 3.7V battery voltage to a stable 5V output, suitable for charging smartphones, powering Arduino boards, ESP modules, and more.
- Comprehensive Battery Protection: Integrated protection IC guards against overcharge (4.2V cutoff), over-discharge (2.5V cutoff), short-circuit, and overcurrent conditions, extending battery life and ensuring safety.
- LED Status Indicators: Clearly visible LEDs show real-time charging status - red while charging, green or blue when the battery is fully charged.
- Simultaneous Charge & Discharge: Supports pass-through operation, allowing you to charge the battery and power a load at the same time (with reduced output current).
- Compact & Breadboard-Friendly: Small PCB footprint makes it easy to integrate into enclosures, 3D-printed power bank cases, or prototype setups.
- Solder Pads for Direct Wiring: Battery connection pads (B+ / B) and optional output pads allow direct soldering for permanent installations.
Why Choose This Module?
- 100% authentic module sourced from trusted component suppliers
- Eliminates the need to wire separate charge controller and boost converter boards
- Built-in safety protection keeps your 18650 cell and connected devices safe
- Perfect balance of cost, size, and functionality for DIY power projects
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse; same-day delivery within Bengaluru
- Expert technical support to help you design and troubleshoot your project
Project Ideas
- DIY Power Bank: Pair this module with a single 18650 cell and a 3D-printed or off-the-shelf enclosure to build a custom portable charger for your phone or tablet.
- Solar-Powered Battery Station: Connect a 5V solar panel to the Micro-USB input for an eco-friendly, self-sustaining charge system for outdoor or IoT deployments.
- Portable Arduino/ESP Project Power: Use the 5V output to run Arduino Uno, Nano, ESP8266, or ESP32 boards in the field - perfect for weather stations, data loggers, and remote sensors.
- Emergency LED Lamp: Wire a high-brightness LED strip or module to the output for a rechargeable emergency light with hours of runtime on a single 18650 cell.
- Wearable Electronics: Compact enough to embed into wearable tech projects, cosplay props, or portable audio amplifiers that need reliable rechargeable power.
- Robotics & RC Projects: Provide regulated 5V power to servo
