Yes, use the Type-C to Lightning cable provided with the iPhone.

Alternatively if you have used a wireless charger, it is also compatible with iPhones, but note that non-MagSafe chargers will only charge at 7.5w, MagSafe will deliver 15w.

I think USB C cables are universal, should be able to charge most USB-C interface(s), except proprietary ones. If I get you correctly, you plan to use a USB-C Cable to charge an iPad with USB-C?

Ah should be easy.

Get a GaN charger with at least 100w with 2 USB C slots - 1 cable for Lightning (iPhone & AirPods), and 1 cable USB C (S20 & iPad Pro).

You're good to go

65w should be okay for most gadgets except powering a laptop. I think you should be able to charge your phone, AirPods and Apple Watch simultaneously with this 65w brick.

Anyone used Samsung S20FE before and changed to IP 13 ProMax? I'm planning to surprise my husband with 13 ProMax for his birthday next week. But not sure if he will feel the phone very weight.

I myself changed from Note 10+ to 13 ProMax and took some time to get used to the phone weight.

Also any light weight case with good protection to be suggested?

I think he might not have problem to change to IOS as he did use iPhone 6 before jumping to android. Although the S20FE is pretty new phone but the battery is degrading like hell. He always have low battery by noon everyday.
I did randomly ask him what he feel abt 13Pro, but he says since his current phone is bigger, 13Pro looks small. That is why I think to go for 13 ProMax.

While I was previously thinking to buy a cheaper range phone for my son for school use, I think it is good that I can pass the S20FE to my son and get my hubby a new one.
