TP4056

A bare TP4056 single-cell lithium battery charger module — the same proven charging IC as the protected variant, but without the load protection circuitry. Charges 3.7 V Li-ion and LiPo cells at up to 1 A via Micro USB input. Use where you have external battery protection or where you're integrating the charger into a larger BMS design.

🔹 Key Applications

• DIY power bank and portable battery pack charging

• Li-ion cell charger integration into custom PCB designs

• Prototyping lithium battery charging circuits

• Solar-to-battery charging with external BMS

• Wearable device battery charging stages

🔹 Why Choose This Module?

• TP4056 proven charging IC — accurate 4.2 V termination voltage

• 1 A charge current via Micro USB — standard USB charger compatible

• LED charge status indicators — clear full/charging feedback

• Compact size — integrates into tight custom designs

• Low component count — minimal PCB space required

🔹 Technical Specifications

🔹 What's Included

1 × TP4056 Li-ion Charger Module (without load protection)

🔹 Pro Tip

💡 For most DIY power bank projects, prefer the TP4056 with protection module (includes DW01 + FS8205A) to protect against over-discharge and short-circuit. This bare version is ideal when you have an external BMS or are building a multi-cell pack with separate protection.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
