    Yes you can, the 13" won't charge any faster with the 87W, the 15" will charge slower with the 61W but they will both work.

  • My 15" Macbook (2016, with touchbar) crashes using the 61w adapter if I'm using a Thunderbolt monitor (and an Apple Thunderbolt 2 -3 adapter). I'm not 100% sure it's the power adapter, but the issue goes away on battery only.
