The Type-C 5V 2A Power Bank Module is a high-performance, ultra-compact solution for creating your own portable charging systems. At Electrapac, we recommend this board for DIY enthusiasts who need a faster 2A charging and discharging rate compared to standard 1A modules.

Product Overview

This module is a sophisticated "2-in-1" power management system. It combines a high-current lithium battery charger with a synchronous boost converter. It takes the 3.7V from a lithium battery and boosts it to a stable 5V for USB devices, while also allowing you to recharge the battery via a modern USB Type-C port.

Key Features for Electrapac Customers

• 2A Rapid Charge/Discharge: Significantly faster than the common TP4056 modules, reducing the time it takes to charge both your battery and your mobile devices.

• Synchronous Rectification: Uses advanced switching technology to achieve up to 95% efficiency, meaning less heat and longer battery life for your Electrapac projects.

• Integrated Protection: Includes "all-in-one" safety features:

  • Over-temperature protection

  • Over-charge and Over-discharge protection

  • Short-circuit and Over-load protection

• Smart Indicator LEDs: Features onboard LEDs to show the charging status and battery power levels at a glance.

• Compact DIY Design: Its tiny footprint makes it perfect for embedding into 3D-printed cases, flashlights, or portable game consoles.

Wiring & Connection Guide

To build a reliable power source with your Electrapac hardware, follow these connection steps:

1. Battery Connection: Solder your 3.7V Lithium battery to the B+ (Positive) and B- (Negative) pads.

2. Output (Load): Connect your 5V device or a USB-A female socket to the VOUT+ and GND pads.

3. The "Key" Button: Many versions of this board include a "Key" pad. Shorting this to ground or using a momentary switch can be used to wake the module or check battery levels.

4. Important Note: Do not use wires that are too thin. Because this module handles 2A, thin wires will cause a "voltage drop" and reduce charging speed.

Primary Applications

• Custom Power Banks: Building high-speed portable chargers using recycled 18650 cells.

• Portable Handheld Consoles: Powering Raspberry Pi Zero or Arduino-based gaming DIYs.

• High-Power LED Lamps: Driving bright 5V LED COB panels for portable photography or camping.

• UPS for Microcontrollers: Providing a backup power source for ESP32 or ESP8266 projects that must stay online during power blips.

• Wireless Speakers: Integrated power management for high-wattage Bluetooth audio builds.
