I am looking for an e reader with specific features, honestly I don't know if what I want even exists, but I figured this might be a good place to ask. Here's my wants:

• Charge via USB-C
• Open, allows .epub files (I understand some brands don't)
• interfaces with Calibre
• Does not have any wireless radios ie bluetooth, wifi (I know lots of people would say just turn those features off, but I would just prefer the device doesn't have them to begin with)

Have you guys seen any devices that meet this criteria?
