The TP4056 1A Battery Charger Module is the perfect solution for safely charging single-cell 3.7V/4.2V lithium-ion or lithium-polymer batteries. Featuring a convenient Micro USB input, this module allows you to easily charge your batteries using a standard wall adapter, power bank, or computer USB port. It also includes direct solder pads for custom 5V wiring.

What makes this specific module essential is the onboard battery protection circuit. Working with bare lithium batteries requires care, and this board includes integrated safeguards to prevent overcharging, over-discharging, and short circuits. It automatically cuts off power if the battery voltage drops too low or climbs too high, ensuring your batteries remain safe and their lifespan is maximized.
