Ratings and reviews

Over time you accumulate many USB chargers and cables. This app let's you see how much changing current these chargers actually deliver to your devices. Also let's you test that new off brand "fast" changer to see if it delivers. I've location a couple of cables that were no longer delivering constant full power to my tablet. Bottom line, this is one of the most useful apps I've found for trouble shooting chargers and cables.

great all, ads are annoying but it's a free app. I recommend it
