It's more like strapping on a exoskeleton suit with a jetpack.

It makes your existing strength and mobility greater, but don't be surprised if you fly into space that you will suffocate,

or if you fly over an ocean and run out gas, that you'll sink to the bottom,

or if you fly the suit in your fine glassware shop with patrons in the store, that your going to break and burn everything/everyone in there.
