|A useful device to have. Ive used it to find the current draw of a few odd USB-powered computing modules. The pigtail cable makes it very easy to turn so you can read the display.|

||Very useful tester.
|Buy this tester and youll find out why some chargers charge your phone or tablet slower than others. A lot of chargers are VERY overrated. Some by 20%. This thing is worth its weight in gold.|

||great little USB charge tester
|I was just expecting the standard volt and current monitor.
But this one has something extra. It also keeps track of
the total amp-hours of charge. There was a tiny button
that was on the top of the case nearest the upper right
of the display, and by pressing this button various display
modes could be engaged.
These are the simple alternating Volts/Amps, or
Volts/Cumulative charge, or Amps/Cumulative charge,
or even all three Volts/Amps/Cumulative charge.
These modes are indicated on the 7 segment display
with bottom-most three segments u for volts, A for
amps and C for cumulative charge.
I tested the cumulative charge up to 5.006 Amp Hours
and the display could handle up to 9.999, but I dont
know what would happen if one goes beyond that point.
