    O chestie de neanlocuit. Se baga in portul USB si in ea (are 2 conectoare) - sarcina, sa zicem un flash stick. Poti vedea daca alimentatorul calculatorului tine 5V, iar curentul nu depaseste 500 mA.

    Pros: ease of use, plug it in a USB port and readout the parameters. Even in dark and/or small spaces very clear to read.

    Pros: Muy bueno, es un árticulo muy útil, la calidad de los acabados es buena. Contras: No tiene contras, lo único es lo que tardan en llegar los pedidos a España.

    Pros: as simple as it can be, good assembly. Cons: my example of this tester doesn't work. If plugged to charger, tester just shows random current (about 1.5A), even if cable and device are not plugged to this tester. I guess voltage is random too. Device is not charging if connected to the but 1... Read more

    An excellent meter to test voltage comes from a USB connector. Also measure the current that is extracted from the USB connector. That way is to check whether the USB connector is not overloaded. The figures are clearly legible. There is no external power required. The meter every few seconds the... Read more
