Compact & All-in-One Safety! TP4056 Type-C USB 5V 1A Lithium Battery Charger Module with Protection for Your 18650 DIY Projects.

Key Features & Benefits

Dual-Input Ports, Universal Convenience: Features both Type-C and Micro USB ports. Can be powered directly by phone chargers or computer USB ports, offering excellent compatibility for easy DIY.

Charger & Protector 2-in-1, Safe & Reliable: Integrates complete lithium battery charging management and protection (over-charge, over-discharge, over-current). Precise charge termination voltage (4.2V±1%) effectively protects your 18650, Li-ion, and Li-Po cells.

1A Stable Charging, Higher Efficiency: Supports up to 1000mA charging current, significantly faster and more efficient than traditional slow-charge modules.

Plug & Play, Easy Activation: Simply connect the battery and a 5V power source to begin charging (initial use may require power connection to activate the circuit). Red LED indicates charging, green LED indicates full charge.

Versatile Applications: The ideal core component for building power banks, powering Arduino/Raspberry Pi projects, reviving old batteries, and various DIY electronic kits.

Product Description
Whether you're building a portable power bank or need a safe lithium battery power system for your beloved Arduino or Raspberry Pi project, this TP4056 module is your reliable and cost-effective starting point. It integrates complex charging and protection circuits onto a tiny board, allowing you to safely manage a single lithium cell without deep expertise. The extra solder pads also make custom wiring a breeze.

🚨 Important Notes / How to Use (Proactively Prevent Negative Reviews)

❌ 【Product Clarification & Limitations】

This is a SINGLE-CELL charger module! Only for one 3.7V nominal lithium cell (18650, 14500, Li-Po, etc.). CANNOT be used for 2S or more series battery packs!

Adequate Input Current Required: Ensure your 5V power source (e.g., phone charger) has an output current ≥ 1A, otherwise it may not charge or charge very slowly.

✅ 【Correct Usage & Activation Steps】

Connect Battery: Correctly connect the battery terminals to the module's B+ and B- pads.

Connect Power to Activate: Power the module via the Type-C or Micro USB port using a 5V/1A (or higher) power source.

Status Indication: Red LED = Charging. Green LED = Charge Complete (or battery is full).

Get Output: During charging or when full, the module's OUT+ and OUT- pads output battery voltage (~3.7V-4.2V) to power other devices.

⚠️ 【Common Misconceptions & Warnings】

NEVER reverse battery polarity! Reversed connection may permanently damage the module.

No initial output is NORMAL: For a new module or after battery disconnection, the OUT+/OUT- may have no voltage output. Connect a 5V power source to activate the protection circuit.

Do not use with already damaged or swollen batteries to prevent safety hazards.

🔧 【Required Skills & Components】

Basic soldering skills are required to attach wires.

A 5V/1A (or higher) power adapter (common phone charger works) is needed.

Recommended to use with an 18650 battery holder for easy installation and replacement.
