With the 5V USB Boost Module, you can charge the battery connected to the module via Micro USB, and you can also enable devices outside to use the Usb A socket by increasing the 3.7V voltage it receives from the battery to 5Va.

It has many protection features such as short circuit protection, high voltage protection, etc. It can flow 1A current from the output. The battery can be charged with 1A. In this case, you can use it as a powerbank circuit.
