“A great little USB tester for the money. Even shows the PD voltages on the D+ and D- lines. Only negative for me is that the display is a little dim unless the ambient lighting is quite low. The smaller is a little ’small’ but overall I am happy with my purchase and I would recommend.”
“Very handy to k ow how much power things are drawing to calculate appropriate battery's needed. You can also rotate the display witch is really really handy”
