I like that I can bring it without any cables for all my Apple devices. I still have a lightning-based iPhone 14 Pro.
The 30W Usb-C PD gives me the option of fast-charging if I bring a cable, but will also work magnetically without one.
The built-in usb-c lets me charge everything else including my airpods.
It works well as an extended battery for the Apple vision pro. Adding a magsafe ring to the vision pro battery makes it super easy to use and the 30W charging is fast.
