Answering peer comments: oh but it DOES work.
I forgot my charger in another town so I bought a USB-A/C cable and tried it out. Again, the iPhone charger is 8W. This is also the value reported by '/usr/sbin/system_profiler SPPowerDataType | grep Wattage'
When the Mac is open and in use (2023, M2) the iPhone charger can just about keep the charge level level, depending on usage.
But then when I close the Mac, it can easily take 10 hours to reach a full charge... but it does hit 100%.
So I am wondering if this is in fact a gentler way to charge the battery.
- Izkata 3y agoMy crude understanding is the charging speed wouldn't directly have an effect, but the heat generated by faster charging would.
- euroderf 3y agoAlso if it takes hour and hours to charge with 8W, then it becomes easier to unplug it at or around 80%. So maybe it's the best way to charge the Mac - a way that all the cool kids will be doing :)
