Q: MacBook Retina vs Air Power Consumption, Off-grid Applications
What is the average and maximum power consumption of the MacBook Retina 12" and MacBook Air 13"? I'm trying to compare these two models for off-grid use and having trouble finding any details. In the real world, which device has the longest battery runtime?
Which would be better for operation off of 12 volt batteries? I need a solution that doesn't involve using an inverter because those waste energy in the conversion process.
Also is the Apple 29 watt and 45 watt power adaptors full range power supplies, can they accept an AC or DC voltage anywhere from 100 to 240 volts? I'm assuming these switch mode power supplies will work on DC input voltage, since AC is presumably bridge rectified to DC anyways. So a battery bank of ten 12 volt batteries wired in series to provide 120 volts DC would work to power the standard Apple power adaptor?
