good and cheap little helper to indicate voltage and amperage. it shows each for a second and then switches to the other. so real time amperage observation is a challenge, but it was expected for the price. see my video for a closer look at the product in action.

Legge amperaggio e voltaggio. Ci si rende conto di quello che arriva realmente nei nostri dispositivi usb quando li carichiamo o li infiliamo in una qualsivoglia presa.

It is really useful. u like being able to see how fast my phone is charging. Also, you can see which charger us the best

A very useful tool, which can show how much current a USB port is delivering (and the voltage). Some phones and tablets can use 2A or more, and it's good to be able to check this. Easy to use and also great value.
