USB Charger Doctor Voltage Current Meter Mobile Battery Tester

The USB Charger Doctor (Voltmeter Ammeter) is a handy tool for measuring the working voltage and current output of any USB-powered device. This blue plastic dongle easily plugs into a USB port, providing an instant readout of voltage and current draw. Featuring a 0.05-ohm resistor in line with the power pin, it accurately measures the current draw while the device passes the data lines through.

The doctor’s digital display alternates between voltage and current measurements every 3 seconds, giving you real-time data for debugging devices like chargers, cables, power banks, and cell phones. Operating within a voltage range of 3.5V to 7V DC (typically between 4.75V and 5.25V for USB devices), it can handle current up to 3A, making it perfect for testing USB chargers, cables, and power supplies. Although slightly bulkier, this device offers quick and reliable readings, making it a must-have for anyone troubleshooting power issues or ensuring optimal performance of USB-powered devices.
