Truly Unique Little Testing Device
Before seeing this on Amazon, I was completely unaware of the fact that something like this even existed. The same applies to everyone I've shared its performance with. It is without a doubt the most unique testing device I now own.I have often questioned the accuracy of reported output on devices designed to charge cell phones and such. This little unit allows me to answer those questions. It has allowed me to confirm there were good reasons for questions that I had. Indeed, only a handful of those items that I've put to the test with this device deliver the output that had been promised. The disappointment created by this discovery is quickly put aside by two facts. Number one, the devices I tested in the end provided the charge that was needed. Number two, the user interface, in other words, the display on this tester, is amazing. The clarity, multiple colors, and adjustable brightness at times succeed in minimizing the negative nature of the data obtained and then beautifully shared.

These test meters are great
Incredibly useful, and this one was the best price of this kind, and I like the short USB adapters vs a cable in the small test box.

Prima hulp
Aangezien tegenwoordig alles op oplaadbare batterijen werkt is dit een handig hulpje dat bij de rest van de meettoestellen hoort.
