Peace of Mind
Simple device which gives you peace of mind that your USB charger/PSU is giving you the correct voltage and displays the amount of current your device (or both devices, it has two outputs) is taking. Very clever idea, handy little device.

No quality check, the one received does not recognised Amp activity.
The one I received does not show any Amp activity what was most important to me. I bought 2 different brands and the other one shows it, but the reason for buying 2 different ones was to check the reliability and now I can't.
