Can you charge iPhone 13 with old chargers?

Yes.

Also see the following from https://www.apple.com/shop/buy-iphone/iphone-13

As part of our efforts to reach our environmental goals, iPhone 13 and iPhone 13 mini do not include a power adapter or EarPods. Included in the box is a USB‑C to Lightning Cable that supports fast charging and is compatible with USB‑C power adapters and computer ports.

We encourage you to re‑use your current USB‑A to Lightning cables, power adapters, and headphones, which are compatible with these iPhone models. But if you need any new Apple power adapters or headphones, they are available for purchase.

5W is the minimum which you can use to charge an iPhone 13. Any previous iPhone charger you've used in the past to charge an iPhone will be fine. If the charging brick is USB A to lightning, as was the case with older charging bricks its fine to use with iPhone 13. You only need a 20W USB C brick if you want to use Fast Charging on your iPhone 13.

I think people are leaving out info/not being specific. They’re making it sound like the charger brick and charger cord should work, unless I’m making the assumption. But based on comments from people saying they still had to purchase something to use the old brick or your new cord if all you have is an old brick, so I’ll try to be specific.

The short answer is yes, the old white 5W brick will work - but not with your new cord.

If you have your old brick AND cord, then you can use it to charge your new phone.

If your old cord is shot, and you were hoping to use the new cord with your old 5W brick, that won’t work without an adapter or new brick. I think that’s where there’s some confusion - some people may just be talking about the brick.

I’ve seen two types of usbc female to usba male adapters: one that looks like the usb connector for wireless keyboards/mouses, and another that has a cord between the usba and usbc connectors.

Examples of both adapters you would need to use for your new cord are attached.

Ultimately you can use your old brick and cord, buy an adapter to use your new cord with your old white brick, or you can buy a fast charger, which is a new kind of brick that works with the new charger cord.

My question is the opposite of what is being asked within this specific forum exchange. Can an Apple high speed USB C cable (with power adapter) be used to charge iPhone's that are older...iPhone X, iPhone Xl, etc.? I can't seem to get a straight answer when I search this question on the web.

It's all forward and backwards compatible. Older cables and/or lower current adapters may limit the current but a newer iPhone will just deal with it. An older iPhone with newer cables/adapters that can provide more power will only take as much as it needs. On top of that, all the Lightning cable does is provide a steady 5V power supply. The actual charging is controlled by the charging circuits inside the iPhone. With a "voltage source" it really doesn't matter how much current can be supplied, as the circuits will limit the current to what's required. It's actually basic Ohm's Law, which is V = I x R. The charging circuits control the value of R.

Can we use apple 5w changer to charge iphone 13 pro max

There’s nothing particularly wrong with that. Even an old first generation USB port (2.5W) on a computer should be fine. It would be slow however.

Yes, but it will take longer to charge. If you charge overnight, every night (a best practice) it won’t matter how long it takes.

You can just use one of your old cables and one of your old power sources. Any Apple branded or MFI certified cable and power source can be used to charge your 13. Or you can get a Qi wireless charger, which is much more convenient than plugging in the phone.

Of course! Juste note that since it’s 5w, it may take longer to fully charge your iPhone.

My new iPhone 13 Pro will charge on ALL chargers, new one with adapter, old chargers - no problem! It’s all good!

Yes.

can I use the charger for my Ipad to charge my new iphone 13?

That's fine.

Go to any Apple Store, Best Buy Store, Staples or order on Amazon, a 20W USB C Charging plug.

Yes, the EU got it right. It was a really smart move to require all portable electronics to use a standard power source and standard cable design. So now you can use your old (or new) LG, Samsung, Huawei, Apple and other brand power sources and cables interchangeably regardless of what kind of device you have. BRAVO, EU!

This is a bunch of BS. If you were so concerned about the environment, why did you change from USB A to USB C?!? Everyone just got through installing USB A ports in their houses, hotels, and businesses. Now the are no longer compatible with your new cord. Give me one good (non BS) reason why you did this. I’ll wait.

FoxFifth didn't change anything from USB A to USB C. He along with everyone else on this user to user only forum is a user. You are not speaking with anyone from Apple. Maybe you should have read the terms of use you agreed to when you joined this forum and you would have known you signed into a user only forum.

We didn't have anything to do with any design change. But it's about time Apple started moving to USB C as far as I'm concerned. Most of the rest of the world has already transitioned. I'm glad they are moving there, albeit slowly.

And so you know, you can't fast charge a newer iPhone without USB C and at least a 20W charging brick. That is if you want to charge your phone plugged in.
