Dear Customer, so sorry to tell you that this adapter won't allow your nikon 1 s1 lenses to mount to my canon t2i. 

Nikon(G)-EOS fit for Nikon G Lens and Canon EOS Mount Camera ,your cannon 80D is E mount camera, so the adapter ring is fit for your camera 

It is a rechargeable battery and comes with a USB-C charging cable, but no adapter. 

This projector doesn't have a built-in battery, but they provided a power adapter in the package. 

FD-EOS fit for Canon FD mount lens and canon EF mount camera body. canon 60d is EF mount, so the adapter ring can work with your camera, but you need to check your lens mount. could you pls let us know your lens specific model? service(AT)kentfaith(DO NOT)com, Please note: It is not same between Canon FD mount and EF mount, this adapter ring is only for Canon FD mount lens, please contact us if you want to purchase for Canon EF mount lens.
