The same charger will work. I initially bought that MBP (was actually the rMB) charger to charge my 12.9 iPad Pro... but I do use it on occasion to charge my other lightning equipped iPads, iPhones, and iPod Touch. There is talk that using it regularly can shorten the life of the battery. I don't know if that is true (my 12.9 Pro is still going strong 3 years later) but I only use that charger with my other devices when I have an emergency need to charge quickly.
