Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This plastic dongle plugs between a USB device, and passes the data lines through.
The voltage regulator generates a fixed 5V output voltage of a preset magnitude that remains constant regardless of changes to its input voltage
We found this little unit great to measure our incoming solar power versus outgoing battery load on a second unit
Place the battery between the two contact points of the battery tester.
The display will tell you immediately if there is the desired voltage.
This module is suitable for indoor use only. This is an entry level measuring solution. Do not expect 100% accuracy.
