USB Charger Doctor for Voltmeter and Ammeter
Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This blue plastic dongle plugs between a USB device and passes the data lines through. There’s a 0.05-ohm resistor in line with the power pin that is used to measure the current draw.
The tester uses a new generation of power four and a half double integral cycle conversion IC, with a precision bandgap reference, range accuracy, high precision, stable and reliable performance, strong anti-interference ability, high temperature can be used for measuring USB powered or power consumption of an interface, cell phone chargers, U disk, and other products.
The USB Charger Doctor measures the working voltage and current output for any USB port and project. This blue plastic dongle plugs between a USB device and passes the data lines through. There’s a 0.05-ohm resistor in line with the power pin that is used to measure the current draw. The Doctor’s digital display instantly reads the numbers out for testing devices such as chargers, cables, and cell phones.
You can use this device from the 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It flips between voltage and current readouts every 3 seconds or so. It’s a very handy tool for testing USB devices, checking load levels, and debugging battery chargers and boost converters. It’s a little chunkier but more numerical than our USB Power Gauge Mini-Kit. It’s also not open source so check out the USB Power Gauge mini kit if you want to hack together your own power gauge indicator. This product is known as 0.28inch 0-100V Three Wire DC Voltmeter Red, 3 Wire LED Voltmeter, Ammeter, Charger Doctor, DC Voltmeter, Doctor, LED Display, Red LED Display, Three Wire DC Voltmeter Red, USB Charger, USB Charger Doctor, Voltmeter, Voltmeter
