I have many of the same device. Nexus 7 in particular.
I'm trying to make sure all my adapters, cables and devices are charging correctly.
I need to know if there is a difference in amperage pulled with the battery is full compared to if its not pulled. does the device still pull the same amount and if its full will the Amps fluctuate a lot or just a little.
