Very Latest New Model

This listing is for a mini USB voltmeter ammeter and energy meter that can can measure voltage, Amps, power and battery capacity, and time connected displaying all readings on a bright backlit LCD display.

Can easily measure the characteristics of any USB port (PC USB, cell phone charger, car charger, mobile battery bank power , etc. ) and any devices operating current, voltage, and charge-discharge capacity, performance

It can show the cause of any slow charging, which could be a charger issue or charging cable issue.Specifically in our experience cheaper USB charging cords can show significant current discharge even without the phone plugged in indicating internal leakage in the cable. This is a quick and easy test for a defective cord. Similarly many cheaper Chargers sold on Trade me with claims of 1 or 2 Amps output are readily shown to only output a fraction of the claimed specs by the use of this handy device

Suitable for the office laboratory or personal use, Easy to use as a standalone meter with no additional power supply, Plug and play.
