iPhone 11 Pro Question on power supply

[dcaccount]

Hello,
I have just bought an IPhone 11 Pro.

In the box I have found the more powerful power supply, the 18W one.

My question is simple, can I use the old power supply (the smaller and less powerful 5W one) or would I damage something?

Please advise, thanks,
Dan

You would be fine using the 5 watt power brick. It would just charging slower which is going to be better for battery longevity.

Yes you can and no it won't.

 

[Never mind]

I’d prefer the 5 watt charger over the 18 watt, and that’s what I use every day. No harm
