As soon as I turned it on the blue, LED window lit up, "100%." Sweet! Hence, I can now charge up my new iPhone to test it.
The blue LED window fades, but, the number remains visible while it's working. This is nice as you can simply pick it up and view it to see where your charge is at. I really like that.
An hour has passed and my new phone is charged. It sitting @ 100%. The charger is standing @ 63%.
