Fastest way to charge Smart Battery Case?

[Pbwj]

I have the iPhone XS Max Smart Battery Case and have been using it with the 12W apple charger. I've noticed it charges a lot faster than the 5W charger. Would buying the 30W make it a lot faster than the 12W? How about the 61W? Sorry if the question has been asked before but Apple doesn't really specify which charger provides the "fast charging."

A usb-c to lightening cable and a power distributor brick over 15 watts will charge it the fastest

I have the 12W with standard lightning cable, I dont see 15W but see 30W chargers on amazon with usb c cables. Does usb c charge faster than the regular usb lightning?

Yes. With a power distributing plug.

I use the Apple 29W USB-C to Lighting set up and it charges the case and phone really fast. No complaints at all.

The 29w/30w will be faster then the 12w. But not a lot faster. The 12w is a great, cheap charging upgrade.
