Anybody have the 30W USB-C charger and the 18W USB-C charger, and have an idea how much faster the 30W is compared to the 18W in fast charging an iPhone Xs?
The phone will only draw so much current. Applying too much charge current cab overheat the battery and even cause a fire. It also means different charging circuitry to handle the higher current. Assuming that’s mitigated, charging a LiIon battery more slowly will increase its longevity.The difference between the 12W and the 18W is not really that big. But I am surprised to see that there is no difference above 18W.....
That’s one of the reasons I never purchased the 18w charger. 12w iPad charger is plenty fast and it came with my Air2 so why spend the $30 for slightly faster charge times
Can yu tell how much is limit for new ipad air 3
I mean what is it caped at ??
Can 30w work for it or 18w will be enough ??
Yeah i agreeI believe it is 18W max anyway for new iOS devices. I think it's the actual device that limits the power input, so it will only draw what needs, so you can use the 30W fine.
Just noticed it's actually sold on (UK) Apple store now as well, so presume Apple tested it and happy! States can charge an iPhone 8 and later (ie fast charge compatible) 50% in 30mins.
