Mini Type C Micro USB TP 4056 1A Charging Module: Efficient Charging Solution for 18650 18500 3.7 Volt Lithium Ion Batteries

The TP4056 is a commonly used lithium-ion battery charging module designed to charge single-cell lithium-ion or lithium-polymer batteries with a nominal voltage of 3.7V. It's widely utilized in various electronic devices and DIY projects due to its simplicity, efficiency, and affordability. The "1A" in its name indicates that it supports a charging current of up to 1 ampere (1000 milliamperes), which is suitable for charging batteries with different capacities. Typically, the input voltage can range from 4.5V to 5.5V DC. This makes it compatible with standard USB power sources.

Now, let's discuss the types or variants of TP4056 charging modules:

1. Basic TP4056 Module: This is the most common type of TP4056 module available in the market. It features the TP4056 charging IC, a few passive components such as resistors and capacitors, and typically includes a micro USB port for input power and battery terminals for connection to the lithium-ion battery. These basic modules often have a single onboard LED indicator to display the charging status.

2. TP4056 Module with Protection: Some TP4056 modules come with additional protection features to enhance safety during charging. These protection features may include overcharge protection, over-discharge protection, short-circuit protection, reverse polarity protection, and temperature protection. Modules with protection circuits are preferred for applications where safety is a primary concern.
