I have a PowerCore+ mini 3350 that I have been using with my iPhone 6S Plus. I recently purchased an iPhone11. Would I be able to continue using this if I bought a new cable? If so, which one would work with an iPhone11?
PowerCore+ mini 3350 can charge an iPhone 11 as well. You can just use a USB-A to lighting cable, like the one for your iPhone 6S Plus.
