With Galaxy Note you can recharge it 2 times without problem! amperage is sufficient for a quick recharge as on the sector. it was my anxiety because the usb port on my pc my phone took a long time to load compared to the cable sector.
well I did not test with 2 peripherals simultaneously. blue LEDs are nice. by against the discharge is not linear.
cote weight and dimension nothing to say it remains discreet. now remains to be seen over time!
