TP4056 Lithium Battery Charger Module 5V 1A TypeC Micro USB Board Fast Charging Protection 5PCS Description

Product: 5V Micro USB 1A 18650 Lithium Charging Module TP4056 Item: 64474 Color/Pack: 5PCS18650 TYPEC Overview This compact linear charging module is based on the TP4056 charging IC and is designed for singlecell 18650 lithium ion batteries. It supports Micro USB input and includes TypeC compatible functionality. The module provides adjustable charging current, precise charge termination, and builtin protection behavior to simplify DIY battery projects and small portable power systems. Key benefits Simple and compact solution for charging single 18650 lithium cells. Adjustable 1A charging current for faster charging when a suitable 1A or higher USB supply is used. Precise termination at 4.2V with 1.5 percent charge precision to protect battery life. Builtin protection behavior reduces charging current automatically if input voltage is, helping protect the IC from damage. LED status indication shows charging and full charge states for easy monitoring. Main features Module type: TP4056 linear charging module Charging mode: Linear, adjustable current up to 1A Charge precision: 1.5 percent Input voltage range: 4.5V to 5.5V Full charge voltage: 4.2V Input interface: Micro USB female, TypeC compatible function LED indicator: shows charging and full charged status Reverse polarity: not supported Operating temperature: 10 C to +85 C Size: approximately 25 x 19 x 10 mm Module number: TP4056 Supply current reference: 1A 1000mA Connections and operation Input: MICRO USB female pads for 5V input. Use a USB charger capable of supplying 1A or more for reliable charging. Battery terminals: B+ for battery positive, B for battery negative. Output/load terminals: OUT+ and OUT connect to the load or to a power output such as a power bank board. Ampere meter: connect only to the 5V input end when measuring input current. Initial activation: when a battery is first connected there may be no voltage between OUT+ and OUT. Apply 5V input to activate the protection circuit, then connect the battery at B+ and B. If needed, short and reopen the B+ B for reactivation. Protection behavior: if input voltage is higher than nominal, for example around 5.2V, the module may reduce charging current below 1000mA. This is a normal protection function that reduces current automatically to prevent chip damage. Important usage notes and warnings Do not reverse polarity. Incorrect polarity will damage the module and may damage the battery. Disconnect the load from the load terminals when charging if required by your application. Ensure positive and negative connections are correct. Charging current guideline: recommended charging current is approximately 37 percent of battery capacity. For a 1000 mAh cell, a charging current around 370 to 400 mA is sufficient. Use wiring that is appropriate for the current and avoid overly thick or overly thin connections; ensure good soldering or secure connections. The USB power source should be able to supply 1A or higher when using a mobile phone charger or USB power adapter to ensure proper charging. Typical applications DIY portable power banks and singlecell 18650 chargers Battery maintenance and charging for flashlights, LED modules, and small electronic projects Integration into small power management circuits and prototype boards that require a singlecell Liion charger with LED status indication What is included TP4056 charging module(s) as specified in the pack: 5PCS18650 TYPEC Item reference: 64474 This module provides a compact, precise, and protected solution for charging single 18650 lithium cells using a Micro USB or TypeC compatible input. Follow the connection and safety notes to ensure reliable operation.
