This USB voltage and current meter is a versatile little tool that can provide voltage readings from 3 to 20V and current from 0 to 3A, which are shown on the built-in screen while your device is connected through it to a power source. It has 2 USB outputs!
Features:
Voltage: 3-20 VDC
Current: 0-3A (error: ± 1%)
If measuring more than 3A, the error would be greater than 3%.
