Digital Tester Current Voltage MonitorDC5.1A30VUSB

 USB meter is mainly used to detect USB charging current, voltage, discharge capacity, quantity of electric charge, power, timing and so on. Meanwhile multi-meter USB detector can be applied to the power capacity storage and over/low voltage-current protection. It allows you to find the charging problem of the USB cables, wall chargers, and car charges more easily.

Features:
