Ottimo tester per valutare la capacità di powerbank o testare alimentatori con uscita usb tipo caricabatterie di smartphone o ancora per verificare assorbimenti di telefoni e di qualsiasi cosa si alimenti tramite presa usb. Unico neo è la mancanza di documentazione che costringe a cercare su internet video che mostrano tutte le funzioni e le operazioni da effettuare per tarare l apparecchio (se necessario) e i vari allarmi che si possono configurare. Questa versione ha una risoluzione più elevata rispetto a quelle più economiche anche se dall'aspetto identico ed è per questo che costa di più. In sostanza sono molto soddisfatto dell'acquisto.

Very good tester works with QC3.0 and even shows the voltage on USB Data pins. Manufacturer could have translated the Chinese writings in the firmware, but they do not interfere because the measuring units are in SI system.

It is the one of very few that can measure voltage on data lines which helps with debugging charging problems. It also comes with the usual features that can be found in similar devices Can measure voltage, current, power, calculate capacity and energy stored on the connected device. It also has that funky usb connector that fits both ways so the display will always be on the right side.

Great USB tester, especially if you want to measure the voltage or current used by the device.

Egyenlőre remekül használható, remélhetőleg hosszabb távon is megbízható mérőeszköz marad.

As described, multiple display output, one of them in Chinese.

It's a Plug & Play USB meter. I haven't measured its accuracy but It is working fine. At least you are gonna have an idea around 1mA or less consumption, during a low energy development project.

Тестером доволен. В сети только положительные отзывы. И вполне заслуженно. Для коллекции инструкция настройки тестера J7-t: Одно нажатие - переключение вида отображения. Одно продолжительное нажатие - сброс всех счётчиков. Два нажатия - сброс счётчика электрического заряд (мА·ч). Три нажатия - сброс счётчика энергии (Вт·ч). Четыре нажатия - сброс продолжительности заряда/разряда. Пять нажатий - установка таймера. Шесть нажатий - переключение языка (китайский/английский). Инструкцию взял с www.youtube.com, канал «Схематик», автор yrie.
