Great product for the price
Always a down side when there are NO INSTRUCTIONS with the item. But I did go on line and found them. Didn't know before the you can download software to keep track of reading. Show it to friends hope you get more sales

Had a problem.
The unit shorted out after a few weeks. However, before that it worked well with a number of useful functions. The issue was resolved quickly

This was great for my son's science fair project.
My son had a science fair project where he was testing solar panel reflectors on a portable solar panel. It had a USB interface, so with this unit, he was able to determine current, voltage, power under various placements and reflectors.

USB tester
I just needed something to show how much current was passing to my on-charge gadgets and what voltages were involved. This works great. Way more information and precision than I need, but the price is right.
A**.
The extra digits in the readouts provided additional usefulness.
The extra digits in milliamps let me see if my charged units shut off at “full charge” or kept a trickle charge below the readability of the other testers.

USB C Input DEAD in 10 mins
Everything worked fine in the first 10 minutes. The USB Type C input port then dead with no obvious reason. The tester won't turn on when plugged in using USB C inputs. Sadly lost $10 value of this thing. Bad purchase.
