Ready to use

Does not work at all. The screen lights up and shows an output voltage of 5V, but no current can flow to the charged device and nothing else is displayed. Tested with 2 different wall adapters and multiple cables/multiple devices - no dice. Maybe I have a lemon. I sent it back immediately and will try the competitor's model.

Pros
  • Ideal for outdoor activities
Cons
  • Reliability

Normal for its price, but the micro USB connector is not durable

Works well. It's nice to have multiple memories to record different readings. The screen is not very bright, it is difficult to see in bright light. Unfortunately, the microUSB port is short-lived. It is only held by 4 very small soldering points. My circuit board broke off and is no longer usable. If you want a more powerful microUSB connector, you'll have to open the box and glue the connection in place.

Pros
  • Many positive emotions
Cons
  • weak

Doesn't work in all circumstances

I couldn't fast charge my phone with it. I wanted to see the voltage and current change as the phone needs to increase the voltage during fast charging. Instead, the meter doesn't seem to allow for any current surge or voltage rise. I imagine it might work for other things where the voltage is expected to just fluctuate around 5V, not sure. I didn't return it because sometimes your time is worth more than the return price. I don't use it, but maybe one day I'll find a use for it.

Pros
  • Good product for the price
Cons
  • Not bad

Useful Tool - Unique Benefits

Units have just been received and are in good condition. I will update the review if my experience changes. The device is small and the display is also small, but with the backlight it is very easy to read. The voltage readings are very accurate, can't verify current draw accuracy, but appear to be at least roughly in the range (ie <1A <0.5A 2.0A). This device has USB-A and Micro-USB inputs. This unique feature allows you to test wall warts ending in Micro-USB and you can also compare…

Pros
  • Easy to Use
Cons
  • Quick Start Guide

Faulty tester for tester

The counter didn't work. I plugged it into the charger and then into the laptop I was testing and got no readings. Tested on a work laptop. I couldn't get any readings and my laptop wouldn't charge. I pulled it out and plugged in the charger as usual and my laptop charged. I tried using my phone which draws around 1A and it worked. It may not be able to handle higher currents. I bought it because I saw a YouTube video where a guy was testing the same laptop I was repairing with the same issue I

Pros
  • Stable results during test
Cons
  • You could have chosen a newer model
