I’m working on a small USB-C power monitoring device that can help makers understand how much power their electronic devices are drawing during charging and operation. The idea is to build a compact tester that measures voltage, current, and power consumption in real time, making it easier to troubleshoot charging problems and test different USB-powered projects.

I want to make the device simple enough for hobbyists to build at home while still providing useful information for electronics experiments. The readings could be displayed on a small screen, allowing users to check whether a device is receiving stable power without needing a separate multimeter for every test.

Key Features

Voltage Measurement: Monitors the voltage supplied through a USB connection.

Current Monitoring: Measures the current drawn by a connected device.

Power Calculation: Calculates power consumption in watts using voltage and current readings.

Live Display: Shows measurements on a compact OLED
