My husband and I just upgraded to 16s and we both had 11s before. When I got the new phones the person at the store said I need to use USB-C to USB-C chargers and that a regular USB to USB-C wouldn’t work. We already have a bunch of usb to usb-c chargers at home because of other devices we have and I’m scared to try to use one to charge my phone because of what the man at the store said (don’t want to ruin a brand new phone). I’ve googled and looked at different forums and seem to be getting differing answers so I’m just generally confused.

There is no useful information about it.I mean it says 30W or greater but does it affect the battery life? And if so should i buy 30W or 20W please help!

I plan to finally upgrade my 6-year-old iPhone 8 to iPhone 16 Pro Max. Back in the day, the charger was included in the box, but now you need to buy it separately (which is not a problem, don`t get me wrong)
I just got confused when I started to look for the charger for my new iPhone... Do I need the 20W or 30W, if I plan to charge my phone with the USB-C cable? Also what kind of cable do I need, cause the 1m cable included in the box would not be long enough for me, I need at least 2m to feel comfortable.

Thank you in advance ;)

Edit:
I Just ordered this cable: https://www.amazon.de/-/en/gp/product/B0BF9JTL8Z/ref=ox_sc_act_title_5?smid=A2CUVTF1JUW5R0&th=1
And this adapter: https://www.amazon.de/-/en/gp/product/B0CX1L2SQ8/ref=ox_sc_act_title_6?smid=A3JWKAKR8XB7XF&psc=1

I hope I did everything right, thanks to everyone who replied, I really appreciate it!

I’m just so confused on which power adapter to get for my IPhone 16 Pro 256 GP. I won’t be using MagSafe to charge my phone, only USB-C cable. Please help. Is 30W even compatible with the IPhone 16 Pro or should I just get the 20W? I know there’s quite a big price difference so I’d like to be absolutely sure.
