Ok, this is a quick review of the RD tech USB 3.0 USB tester

This was sent to me for review by RD tech.

So basically this is a multimeter for your USB port. Pretty simple and basic. It allows you to see the voltage and current passing through the USB port at any given time. Good for diagnosing charging issues or seeing if your chargers are telling the truth.

It also includes a charge “counter” that keeps track of how much total power has been consumed. This will not be precise due to losses in the charger but it is a nice feature.

No real complaints while using it besides the sreen times out after about 10 seconds and you have to wake it back up.

The graph modes are nice for seeing what it does over time. For example you can see when the constant current charge ends and the constant voltage begins.

It seems to be pretty accurate, although I don’t really have anything to compare it to, it matched my multimeter pretty well.

Now for some pictures:

These things are really good for checking things with a proprietary battery. I don’t have this particular model but I have a couple of others.

Yeah, they can be used with your phone or any other USB device as well to get an idea of what is going on inside.
