I want to go from this:
The converter would be this: http://smile.amazon.com/dp/B00HVCWGNE or something like it.
Does this sound safe?
The step up converter would be set to a specific output voltage and remain there. This bothers me insofar as it relates to a statement on Ken Sheriff's blog about Apple's "charger:"
The charger provides a very low current...6 volt signal on the power pins (3 volts for Magsafe 2).
I don't know if he means the adapter or the connector that plugs into the laptop. I want to make sure all the 3rd parties that already produce something like this don't know something about the 3/6 volts that I don't.
