FEATURES:

1. It can be used to measure the empty USB-powered devices, voltage loads, USB terminal device while operating voltage and current.

2. Current, voltage cycle, easy to use and practical.

Measuring range: DC 3V-9V, current: 0-3A (error: ± 1%) maximum support 5A

5A current (3A after the error will be larger than some 3% of the way).

Weight: 25g Packing: anti-static bag

The latest operating current USB voltmeter ammeter can easily measure the USB port of the output voltage and the device!

PLEASE NOTE: It can only truthfully display real-time voltage and current electrical work, do not have the function of the discharge device that can not be set to a certain voltage certain current discharge! Compact, no power, and other ancillary equipment, plug and play! Also detect any USB charger (computer USB, home charger, car charger) charge current and voltage in order to determine the performance and the performance of the charger charging cable meets the requirements! Wide range of applications, any phone, any electronic product, you can use, easy to operate, suitable for factories, show presentations, laboratory and users!
