MagSafe and case question

Hello, I wondered if anyone had a MagSafe charger unit (the one that stands straight up looks nifty) and if so does it make a high pitched whine noise when it’s charging? My current wireless charges make a noise and I am looking to put it right next to my bed so would prefer if it wasn’t distracting.

Also, does anyone have the Apple official silicon case for an iPhone? If so would you recommend? Pricey, I know, but hoping it will last. Thanks in advance.

Edit: Thanks for the replies everyone!
