TIA for all info.
Regarding the M2 2022 MacBook Air - I understand it has a MagSafe 3 port and two USB-C ports. If all I have is a double-sided USB-C cable, can those two USB-C ports accept charging if I plug a charger+USB-C into it? Or is charging the laptop thorugh the MagSafe 3 port the only option instead of an additional one. Google search etc was ambivalent, in all results it wasn’t clear to me if those usb-c ports could be used only to charge other devices from the laptop battery of if they can also be used to charge it.
It shouldn't damage anything, but it might not be powerful enough to keep up.
The Macbook Air charger is 30w, which is about 6A.
Amps are "pulled" by the computer rather than "pushed" by the power supply [which is the opposite to voltage; this is why voltage has to match but amperage doesn't] however, your charger will be incapable of supplying all the Mac is asking.
This will just make charging slower. If you're lucky, it might just keep up, otherwise the battery might still lose charge slowly while the Mac is in use, even with the charger connected.
I didn't think it would... but the ubiquitous Apple 12W USB-A iPad/iPhone charger
works fine for me when my M1 MacBook Air is shut down. The battery life is good enough to handle moderate use (take measures to minimize drain!) and then I just plug it in when I'm not using the laptop, shut it down and it charges slowly. (USB A to C cable needed) Definitely needs extra time but is usually charged in a couple/few hours.
I guess the only question I have about this would be - is there anything wrong with leaving that setup (12W USB-A charger, USB A to C cable, M1 MacBook Air) plugged in while I'm working on the computer? I have heard that it's best to not drain and charge at the same time. So I guess more generally I need to research the entire question of charging while using.
My wife recently got a 2018 MacBook Air Retina screen and it came with the 30W charger. I have a 13" MBP with the 61W charger.
I found out today that not all Apple USB-C charge cables are created equal (https://support.apple.com/en-us/HT201700). What a mess. I can't seem to find any technical specifications for the rating of the cable shipped with the new MacBook Air based on the serial number on the cable.
The cable shipped with the 2018 MacBook Air has first 3 SN on the cord: G0J. This serial number isn't listed in the apple support page. Is this Apple support page out of date based on the serial numbers that are shown?
I was able to match the SN of my MBP cable to the guide (SN: DLC which supports the 61W/87W chargers).
It would be nice to know if the new cables shipping with the MacBook Air Retina Screen system support 100W max (20V @ 5A).
I've had my M3 Macbook air for about six months now and for 99.99% of the time it is plugged in except for the occasional unintended un-plugging. I use a genuine Apple USB-C to USB-C cable plugged into a genuine Apple 140W Apple Power adapter. Despite the always pugged-in mode, I'm up now to 64 battery cycles and 98% battery health. Last month I was at 43 cycles/100 Health and hadn't used the MBA once in between.
I don't think my battery has ever discharged more than 10-20% 2-3 times since I got it. I know many comment here not to pay much attention to battery cycles since the battery is a consumable, but it is concerning that the battery health has degraded and the battery cycle count is so high despite it being plugged in nearly 100% of the time.
My question is whether in anyone's experience, is it better to use the original Mag safe usb-c cable rather than a usb-c to usb-c cable to keep the MBA charged? Does using the 140W charger as opposed to the original charger make a difference as a effects battery health?
Reason I'm concerned is that I usually upgrade each time a new model with an upgraded processor comes out, and I do re-sell my old unit and want to get the best possible price for my used unit when I sell it. One of the first questions buyers always ask is how many battery cycles and battery health status. I pretty much used my M2 Macbook Air the same way and ended up with a ridiculous 113 cycles even though it never left me desk once. Battery health was 95%. It was less than a year old at the time.
Any thoughts appreciated.
