Frequently Asked Questions

Q: Is the TP4056 charging module compatible with all 18650 lithium batteries?

A: Yes, the TP4056 module is designed to charge standard 3.7V 18650 lithium-ion cells. It charges to a full voltage of 4.2V ± 1%, which is the standard specification for most 18650 lithium batteries used in DIY electronics projects.

Q: What is the difference between the standard TP4056 and this two-in-one version?

A: This two-in-one TP4056 module combines the charging circuit with a built-in battery protection circuit on a single board. The protection circuit safeguards your lithium cell against overcharge, over-discharge, and short circuits — giving you greater safety and peace of mind without needing a separate protection board.

Q: Can I use a standard USB phone charger to power this module?

A: Absolutely. The module accepts an input voltage of 4.5V–5.5V, which is the standard output range of USB chargers and power banks. Simply connect via the Type-C or Micro USB port and the module will handle the rest.

Q: How do I know when the battery is fully charged?

A: The module features two LED status indicators. A red LED lights up during charging, and it switches to a green LED once the battery is fully charged — making it simple to monitor charging status at a glance.
