The Amba Solo is made of 304 stainless steel so it is anti-rust/corrosive, so theoretically yes it will. However you would need to clean the unit every few weeks to remove any harmful residue or chemicals from the surface.The only concern I would have is with the switch and cord. There could be a chance of water getting inside the unit where the switch is at the top of the unit or where the cord comes out of the unit. If it is protected enough so that a storm isn't going to pour down on it, you should be fine.
