USB Voltage and Current Monitoring Module doctor

Using this module, it is possible to measure and display the voltage or current consumption of all devices that have a USB port. The USB port voltage typically ranges from 4.75 to 5.25 volts, and this circuit does not require any external power supply; however, it is capable of measuring voltages from 3 to 7.5 volts with a current of 2.5 amperes. By using the USB voltage and current monitoring module, you can measure the charging power of the USB port of the computer, a charger adapter, a power bank, and several electronic devices. Additionally, this tool allows you to check the charging rate of your mobile and tablet cables.
