Excellent tool for measuring the output on a USB port and ot both USB-C and classic USB-A and microUSB.
It can retrieve information from the Power Delivery device and offer the corresponding measurement type
Can test port options by USB type
Supports PD 3.0 and QC 3.0 (there is a switch for PD)
It has a gyroscope, but the display rotates 180° if you need to measure in a different position
Excellent and intuitive control with Joy ring wheel and back button
Can measure cable parameters
Connection to PC via microUSB cable
Always use the appropriate cables. Thus for Fast charging cables with the necessary parameters.
The user has to labor for a while. The Czech manual can be found on the internet, but it only describes the functions, but without an example of use

Handy USB meter. When charging from a USB port or charger, it displays charging parameters (voltage, current and power) and can be connected to a PC to display the battery status of the device being charged and other parameters.

Pelkne zariadenie , kvalitne spracovanie , velky display. to je ale asi vsetko. Katastrofalne riesene "rozpoznanie" pripojenych zariadeni. Casto zvoli iba minimalnu rychlost nabijania 5V. Aj ked je toot zariadenie schopne rozpoznat takmer vsetky protokoly , pri zapojeni medzi nabijacku a nabijane zariadenie casto nie je schopne "preniest" informaciu o podporovanych protokoloch a nabijane zariadenie sa nabija vyrazne pomalsie. obcas pomoze "nahodne" odpajanie a zapajenie ako nabijackybtak aj nabijaneho zariadenia. Niektore zariadenia vsak nikdy nedoaiahnu maximum. Na otestovanie powerbanky vsak posluzi
pekny dizajn

I've only had it for a day, so I'm testing it. Everything's working as it should. The manual in English can be found on the net. Apparently it is not a Chinese product, as only English or German can be selected in the settings. The priority is German. No Chinese character anywhere I'm still going to try connecting to the computer, since that's an option.
Lots of features
So far I'm satisfied
Absence of any manual. is not even in English

Coincidentally, after a sad experience and disappointing delivery reports on another eshop where I had a slightly newer tip ordered, I came across this USB tester here, and for next day delivery I did not hesitate to purchase here. Yes, sadly, a person who is not familiar with it will not find instructions here, but this tester is identical and actually identical in program to the FNIRSI FNB58, so it is possible to find plenty of videos on youtube on how to use this tester.
It does exactly what I bought it to do.
