It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects.

The box of Anker Nano Power Bank (22.5W, Built-In USB-C Connector) looks like this. Inside was the mobile battery itself, a USB Type-C cable for charging, and an instruction manual.

The Arduino Nano Every is faster, cheaper, and has more memory than it's predecessor, but what is it, and what can you use it for?
