I'm wondering if it's safe and reliable to power an Arduino board (like Uno or Nano) using a regular phone charger through the USB port. Are there any voltage or current considerations I should keep in mind?

A standard 5V phone charger (with at least 500 mA output) and a proper USB cable are usually perfectly fine for powering an Arduino Uno or Nano via USB. Just double-check the specifications of your charger to be sure it's not outputting more than 5V
