TP4056 Li-ion Charger Module — Type-C / Micro USB, 5V 1A, 18650 with DW01A Protection
This TP4056 charging module combines the TP4056 CC/CV Li-ion charger IC with a DW01A battery protection IC and dual FS8205A MOSFETs on a single compact PCB. It provides complete single-cell Li-ion and LiPo battery charging (4.2V, 1A) with full protection against overcharge, overdischarge, overcurrent, and short circuit — all accessible via a USB Type-C or Micro USB input. The most popular ready-to-use charging module for 18650 cells, LiPo packs, and DIY power banks.

Why Choose This TP4056 Module?
- Type-C + Micro USB dual input — compatible with modern USB-C chargers and legacy Micro USB cables
- DW01A full protection — safe to use with bare (unprotected) 18650 cells and raw LiPo packs
- Dual LED indicators — red = charging, blue/green = fully charged, easy status monitoring
- Separate B and OUT pads — B+/B− connect to battery; OUT+/OUT− provide protected output for the load
- Compact 25×17mm PCB — fits inside most project enclosures and power bank cases

Frequently Asked Questions
Q: What is the difference between the B pads and OUT pads on this module?
A: B+/B− connect directly to the battery terminals (before protection circuit). OUT+/OUT− are the protected output after the DW01A/FS8205A protection circuit. Always connect your load to OUT+/OUT− to benefit from overdischarge and short-circuit protection. Connect the battery to B+/B− only.
Q: Can I charge and use the load simultaneously (pass-through charging)?
A: Yes, but with limitations. The TP4056 charges at 1A maximum. If the load draws more than the charging current, the battery will discharge even while connected to USB. For stable pass-through, ensure the load current is less than the charge current (1A). For higher load currents, use a dedicated power path management IC (BQ24074, MCP73871).
Q: How long does it take to charge an 18650 cell (2000mAh) with this module?
A: At 1A charge current: approximately 2–2.5 hours for a fully depleted 2000mAh cell (accounting for CC→CV transition and termination). The red LED turns off and blue/green LED lights when charging is complete (current drops to ~100mA termination threshold).
