TP4056 5V 1A Lithium Battery Charger Module | Type-C/Mini USB 18650 Charging Board with Protection for Li-ion Batteries

Product Description

The TP4056 Lithium Battery Charger Module is a compact, reliable, and highly efficient charging board designed for single-cell 3.7 V Li-ion or 18650 batteries.
It integrates a TP4056 linear charging IC with DW01A protection circuitry, providing over-charge, over-discharge, and short-circuit protection for maximum battery safety and longevity.

Available in both Type-C and Mini-USB versions, the module can draw power from a 5 V USB source such as a charger, power bank, or computer, delivering a 1 A constant current charge.
This makes it ideal for DIY power banks, IoT devices, battery-powered Arduino projects, and any portable electronics requiring safe, efficient charging.
