USB tester for displaying voltage (3.57V) and charging current (03A). An excellent solution for understanding how much your gadgets consume current. See the average current consumed multiplied by the charging time and we get the capacity of your battery. USB тестер для показывания напряжения (3,57V) и зарядного тока (03A).
Отличный решения для понимая сколько ваши гаджеты потребляют тока.
Смотрим средний потребляемый ток умножаем на время зарядки и получаем емкость вашего аккумулятора.

This tester is very useful. It is very easy to use but provides an excellent and accurate indication of the voltage and current supplied by the USB port. Cons: The indication of voltage and current changes automatically every 34 seconds, shame there is a button that allows you to keep the same view! Questo tester è utilissimo.
È semplicissimo da usare ma fornisce un ottima e precisa indicazione della tensione e della corrente erogata dalla porta USB.

Cons:
Lindicazione di tensione e corrente cambia automaticamente ogni 34 secondi, peccato non vi sia un pulsante che permette di mantenere la stessa visuale!

I didnt expect it will work so well. It shows voltage and current data in the same time. It shows good meters. Easy way to check if your device is charged in the way it should be. And good way to check if your charger gives what it is expected to give. I didnt expect it will work so well. It shows voltage and current data in the same time. It shows good meters.
