Chargers

[brvision]

Thank you for taking the time to do the analysis and chart. I see from this that a 6' cable drawdown in amps can be enough to set off "slow charging". I'm wondering if the amps received at the phone using a 2.1 amp charger with a 6' cord may get close to the desired amp of OEM at 1.8? Also, I see chargers advertised of various amperages that have no correlation with their output in wattage. . .what' going on here do you think? Thanks
