What it might be?

Hi! I got an iPhone 14 pro a few days ago. It came with a USB-C > lightning cable but obviously no plug. All of my previous iPhones have come with a USB-A > lightning cable, so all of my plugs have a USB-A port. So far, I’ve been charging my 14 pro with my old plugs and cables. I’m using an Apple 10W plug (which came with my iPad mini 2).

My question is, does this matter? I’ve only had to charge the phone twice so far and it seemed to charge pretty quickly. Should I spend £40 on a new plug with a USB-C port so I can use the new cable that came with this phone, or is it ok (battery health-wise) to keep using the old hardware? Is it just a matter of speed, or is this set-up going to be bad for my phone?

Hi! So I got a iPhone 14 when they came out. Long story short I have a usb c cord plugged into my device/laptop and it won’t charge. I guess it’s possible there is an issue with the cord/device but I don’t think it is. I can charge other devices with the cord/usb c port but not my phone. The odd thing is if I take the cord/phone, plug it into another port it works just fine and if I leave it plugged in long enough and plug ir into my laptop it will hold a charge. Again it’s certainly possible it’s a problem with my device/cord but I don’t think so. I have tried a couple of cords in my laptop and I have the same problem. I’m starting to think it might be a handshake issue/problem with the port itself. Any ideas? Sorry for the long winded post.
