Ammeter USB pocket

By having several, several brands, I was curious about the real qualities of each.

This small pocket ammeter is a harsh judge and an ease-of-use: simply insert between the your source and USB cable.

Big relief, but batteries are of a rather homogeneous quality (0.1 A difference between the most powerful and the less powerful.

>> The real surprise is that this little ammeter allowed me to make a real discovery!
> Smartphones, Tablets, etc. come with a USB cable that can recharge and connect to a computer to transfer data (I'll call the "USB data cable").

> The Batteries are usually supplied with a USB cable that allows only the load (I'll call the "USB cables")

-> Well loading speed with a USB cable is 3 TIMES FASTER than with a USB data cable !!

I finally have an explanation to the mystery of the apparatus that loads at different speeds depending on her mood: it just came from the cable.

Just for that, I am pleased to have invested in this 8.99 ammeter, and I recommend it!
