USB Testers
USB testers are pocket-sized measuring instruments that are plugged between a charging adapter and the powered device to show the voltage, current and transferred capacity on the USB line. They are used to see how much current charging adapters, portable chargers, cables and USB ports actually deliver, and to tell whether a fast-charging protocol has kicked in. The Unit UT658 family in this category includes Type-A, Type-C and dual-output models and the UT658LOAD with an electronic load function; besides voltage and current measurement, the product data includes capacity in mAh, energy in Wh, D+ and D− data line voltage and a 10-record memory. Compare the port type (Type-A, Type-C or both), the voltage and current range to be measured, the capacity and energy counter, the recognized fast-charging protocols and the record memory according to your intended use. A USB tester measures the power line; it is not a USB protocol analyzer that decodes data packets.
