    Instrumento muy útil para diagnosticar procesos de carga y consumo de algunos dispositivos. Es muy preciso en sus mediciones, comparado con un instrumento profesional, la diferencia es despreciable. Muy claro en sus indicaciones.

You plug this into an available USB socket on your PC/laptop or charger and plug whatever you want to charge into this. It's called Charger Doctor. You will know if something is 5... Read more

    Bought to test car charger, battery pack and computer usb power outputs. Serves well - now it is easy to understand which charger and/or wire is better for fast charging my phone or to discover wires that are loosing their connection.

    Funguje dobře, nevím jak je měření přesné, protože jsem to nekontroloval. Je to výborná věc pro posouzení nabíječek jak fungují a která je vhodnější na nabíjení spotřebičů s větším odběrem.
