Febreze Plug in Air Freshener with Warmer & Scented Oil Refill, Linen & Sky, 0.87 Ounce

Where can I find a plug for the bottom socket? My top socket has a light switch instead of a top socket. I need something that will fit the bottom

How often is the scent released? It is not all the time because I can smell a stronger scent when released.

What is the current draw of this device?

Will it work on 220-volt socket?
