The module is built with TP4056 lipo charging chip. It can charge 1-cell lithium batteries or charge parallel connected batteries. TP4056 is capable of precise charging due to its simple circuit structure, good protection feature. This module has a fully automatic charging mechanism. It is made of SMD materials.

TP4056 5V 1A Mini USB Lipo Battery Charger Module

The charging current is set at 1A. Most phone/USB chargers today give 1A and above. To be sure, you can look at the values on the phone charger. If you want, you can change the current value by changing the resistance.

You can adjust the output voltage according to your request via the trimpot on it. This module, which is very useful with its small dimensions, has the LM2596 regulated integrated on it. The circuit can carry current up to 3A DC. A small deviation margin of 30 MV provides a great advantage over other DC-DC converters. Note: Since the product is a voltage reducer, the output voltage cannot be more than the input voltage. If you connect a 30V input, you can set the desired voltage 0-30V range. However, if you connect 12V to the input, you can set the output range of 0-12V.
