Este medidor veio bem embalado, com manual de fcil entendimento (em ingls). Particularmente para mim foi muito fcil utilizar o produto, mesmo sem ter lido a priori o manual de instrues. H um boto que alterna entre os dados de exibio. Recomendo.

Takes the guesswork out, on how much power your pulling out of your USB port..

Very very usefull device.
It is not only a measurement device, it is also a sort of 'simple analyzer'.
It starts to measure when the load is attached on USB port (it 'beeps'),
and stops when load is removed, keeping in memory the mAh measured.
It completely reset when unplugged from power source.

Works as advertised! Although I do not know, what the EL value stands for. I assume time in minutes, therefore I switched it off. Wanted to see how deteriorated my old battery in my iphone 4 really is. Still charges 1100 mAh, when completely empty... Now I could put in a new battery and see whether it comes over the given capacity (1420 mAh). But probably not either, as the phone switches off at a voltage which will be for sure high enough not to damage the battery...
A must have for people who like to measure.. :)
