Amp it Up
Works perfectly straight out of the box, i use it to see what current is being drawn from my repairs. It works with a multitude of adapters. Crystal clear picture on the screen and very informative. For the price paid, this is an absolute gem of a device. Must have for any repair enthusiast!

Works great!
For the price I cannot fault it and it's a really handy bit of kit for running quick tests.This is a small unit so the display is small, but it is clear. Unit does appear to be accurate, and I've been using it to check power delivery from chargers and PC ports, as well as to check some cables I thought were causing charging issues (this unit confirmed some cables I had really dropped the delivered amps).

Useful to diagnose issues
Very useful to diagnose drained devices that don’t manifest any charge characteristics.

Good but only used half a dozen ties so time will tell.
Does everything the description says. I was worried at first because it rattled when shook but this was just the button moving in it's hole. Whether this becomes a problem later has to be seen.
