#CHARGER FOR MACBOOK AIR MAC#

Ideally, just feeding it enough power to not use the battery. So since Apple doesn't have that, I'll slowly trickle charge it.

#CHARGER FOR MACBOOK AIR MAC#

Set desired charge level to, say 70 or 80%, and the mac automatically stops charging when it hits that level. I really wish Apple would implement a charge level cutoff, like a Tesla car has. I don't want to constantly plug and unplug my mac during the day to stay in the sweet lithium charge state. The quick charge is stressful, as well as leaving it plugged in after charge. I don't want to quick sear charge to 100%, then slow cook the battery all day. Going further, I much prefer a sloooow trickle charge for my macpro. The more common case is a forgotten charger, or being in an airplane seat with only a USB-A available. That high capacity allows for charging the battery very quickly, even while using your Mac to the fullest.

I'm bucking the 'gotta have 61 or 90 watts of power!' trend. MacPro USB-C can be charged with old style USB-A power sources

Works fine, and doesn't 'drain your mac' as some people incorrectly guessed. Someone did a nice youtube video on exactly that- charging your macbook via usbc from the regular old style usb sockets. Your best bet is to get a proper USB-C travel charger and hopefully the airplane will have the 12V sockets (car cigarette lighter port) rather than USB ports.ДЄs for the cables you need, if it's a USB-A port, just the USB-C to A adapter you already referenced and a USB-C cable which you should already have. As for the power draw, it will draw what it can - if the airplane only supplies 5W that's all you'll get. Then, when it was running low on battery today I plugged in the wall charger (which is a new one I got in July) and suddenly my screen went black and the charge light wouldnt come on. It will go faster if it's a 12W or 15W port, but still be quite slow. Question: Q: macbook air wont charge & no light on charger I charged 2011 Macbook Air yesterday and it was fine last night and again this morning. So, if you use a 5W charger (airplane, car, etc.), it will take forever to charge that MacBook (you'll drain battery if you attempt to use it while charging), but it will charge. Otherwise, it will simply draw the maximum which is no more than 12W (5V at 2.4A) If it can negotiate up (to a max of 20V) it will do so. The default charge that comes from a USB-PD device starts out at 5V - this, coincidentally is the same voltage that legacy USB chargers output. The Type C ports on your Mac conform to the USB-PD (Power Delivery Spec) meaning it will negotiate for the maximum charge. I read somewhere that the new MacBook Air computers (the ones with USB-C) can be charged slowly from any USB source using a USB-C to USB-A adapter.
