got that many lightning cables that I hadn't unpacked the cable my app came with, but last night I unraveled it and its lightning to usb-c

have to admit im confused by that, especially since it doesn't come with a wall plug. my initial thought was one of disappointment as I didn't think I had anything that would accept it but then remembered theres a spare thunderbolt socket on my imac.

so its a win already as it frees up one of my usb sockets. but why doesn't it then come with a plug?

few questions.

will it charge APP/iPhone etc at the same speed or quicker than the usb socket?

would buying a usb-c wall plug lead to faster charging?

Just use any lightning cable. Charge speed will be the same; usb-c only improves charge speed with appropriate charging brick on iPhones and iPads.

I think it is the same, up to 5 watts either with C or A (or even Qi wireless, for that matter).

Also I have the Macbook Pro with USB-C and it offers up to 15 watts through its C ports to other devices, the iMac with C is the same. So that is pretty decent for power and you typically wouldn't need a brick if you want to use the Mac to charge your smaller devices. I could charge almost everything smaller than the Macbook Pro itself with the Macbook Pro's USB-C ports.

so would that mean that using my imac 2017 it might charge my iPhone quicker through the c port than the usb3 port?

If you have the 5 watt adapter for your iPhone, the iMac may charge slightly faster.

It should, but probably not too noticeably. The A port should be able to deliver 2.4 amps (12 watts), the C port can deliver 3 amps (15 watts). iPhones don't charge at full speed the entire time, whereas something like the iPad or even a Macbook with USB-C could charge at the maximum rate allowed for most of the charging curve.
