iPhone 14 Pro Max Can you use the old 5w charger for 14 pro max?

Because they discontinued it and want to sell people new chargers (also because the 5 watt charger takes a long time to charge bigger batteries)
True, but iPads used to come with 10 and 12 W chargers and that was never seen as a problem. Their batteries eclipse that of any iPhone.
This is one they offer (3rd party): https://www.apple.com/shop/product/HN892ZM/A/mophie-usb-a-cable-with-usb-c-connector-1-m
The iPhone with USB-C will likely work just fine with 5 watt chargers.
It's not nonsense. Whether you like it or not, heat will slowly degrade a battery. Fast charging generates more heat. It's as simple as that.
It’s not nonsense. Slow charging = less heat = slower degradation.
Many go by 20-80% charging patterns and all that, I give one advice: charge as slow as possible.
I throw every battery conservation technique out of the way, because I don’t care about it, but I do two things to get the best possible battery life:
-I don’t update iOS
-I charge with the slowest possible charger
I have never replaced a single battery. My iPhone 6s is at 63% health on iOS 10 and battery life is flawless.
If you want to charge with a fast charger, that’s fine, but it will generate more heat. If possible, it’s always best to charge as slowly as possible.
There is so much advice on this that just is completely false or makes so little of a difference that it's not going to be noticeable or worth it:
The only "battery life habit" that can impact your smartphone's battery life in a manner that's significant enough for you to notice it, is by reaching one full charge-to-discharge cycle later rather than sooner.
If you use your iPhone less and/or enable Low-Power mode, you could, potentially go 2-3 days between charging instead of charging every single day.
This is, obviously, also more likely to happen if your iPhone has a battery with more mAhs rather than less.
However, regardless of how big the battery is, how fast the SoC, or how many days go between charging -once you hit the 500 cycle mark, you're battery will be at about 80% give and take your unique living conditions(high temperature year round is slightly worse), and whether or not you got a "lemon" or not.
I hate to say it for the 5000th time, but having charged nothing but 5w, no wireless, no fast charging does not help you whatsoever once you reach 500 charge cycles.
You can't trick the (fairly) fickle chemistry of a battery.
Apple's smart charging algorithms make the impact of fast charging close to zero which is why they do not recommend slower charging over faster.
Only sustained hot temperatures hurt your battery. But that's not occurring unless you constantly leave your iPhone sitting in the sun.
You can't trick the chemistry of a battery. Only using it less with give it a significantly longer life due to reaching each of the 500 cycles at a slower rate.
Apple isn't lying or pushing you to replace your battery faster -The fast decline happens at around 500 cycles no matter what you do.
Stop all the babying and enjoy your market leading smartphone. Or get AppleCare if you can't stand the thought of your battery being anything but >80%.

Exactly.
The iPad 9th gen has a 8500 mAh battery, almost twice as big as even 14 Pro Max at 4323 mAhs.
The reason why fast charging an iPad "was" never a problem, is not because iPads have a different type of battery or other properties.
It's simply due to the fact that you're going to reach the 500 cycle mark way later with a battery that has double capacity.
And also because you don't carry your iPad on you and constantly pick up your iPad all day long, take/make calls over cellular, etc., like you do on an iPhone.
Fast charging your iPhone makes a negligible difference if smart charging is enabled.
It's the charging once per day or more that's really making the difference and getting you to <80% so much sooner than with an iPad.
It should still work with an A>C Cable. Just can't use the existing Lightning ones
I started using the iPad one once iPhones would charge faster with it. Was that 5 or 5S?
Yes, but I don't know why you would want to. It'll take forever to charge your iPhone.
I care about absolutely none of those things and have also never replaced a battery. Ever. Some of my phones are still in use as hand me downs 5 years later.
All of it is absolute nonsense and there is no reason to baby your phone. This is paranoid delusion. Just it use.
It's absolutely nonsense. All forms of charging with degrade your battery. None of them will degrade it fast it enough that it matters at all. It certainly shouldn't change or shape the way you use the phone.
I mean, it charges overnight. If you sleep you wouldn't mind.Yes, but I don't know why you would want to. It'll take forever to charge your iPhone.
If you don't sleep, then, uh, get help.
Phone manufacturers have taken steps to minimize the impact of fast charging on the health of their batteries, but that doesn't make the impact zero. I agree that people need to do what works for them, but if at the end of the day you tend to charge your phone overnight while you are sleeping why wouldn't you use a slower charger as it isn't changing the way you use your phone at all.
It does however make it insignificant, and not something anyone should be thinking about or changing the way they use the phone as a result. Charge with 5W or 100W, wired or wireless, it Does. Not. Matter. The phone will still work perfectly fine, and last as long as it should.
I have used my old 5w charger to charge my 3rd gen iPad Pro. Plug it in, turn it off, and wake up the next morning with a fully charged iPad.
If 5w is too slow for you, I notice that the 12w chargers that came with the old iPads also does not make the phone hot and charges a little bit faster.

Stay on an older iOS version and health and cycles don’t matter.

Fast or slow charging does make a difference, but I agree with you in spirit: caring about the battery health - especially if you update iOS - is pointless. Any battery health gain is made irrelevant by the sheer impact of iOS updates on battery life. New battery? It won’t fix that impact.
Doesn’t this make the charger hot? I’ve inadvertently used a 5w charger on a 9.7-inch iPad Pro and I didn’t like the charger’s temperature when I noticed (many things charging together, cables jumbled in the middle, I unwittingly used a 5W charger on an iPad).
No, as it can only pull 5w, which the wall wort is rated for. My iPad Pro is 4 years old, no issues. I did warranty it out this year though, I dropped it. Admittedly, I only charge the iPad Pro about once a month because I’m lazy don’t want to get out of bed to grab the USB-C charger. I use the five watt to charge my phone at night and keep a spare cable for the iPad…only for sheer convenience though. I use a nice (imo) Anker A to C cable. My only tip: turn of the iPad Completely, otherwise you get virtually no charged battery When you wake up 8-ish hours later ✌️
Yes, and technically it’s even better for your battery long term. Even better if you take it off when you reach 100%. And even better if you take it off at 80%.
