I'm not aware of any small portable devices that contain their own "mains" power circuit. The necessary size of the circuitry and the bulk of the required cord connector make this approach a non-starter.

You'll find that all existing tablets and ereaders use an external "brick" of some sort to provide the "mains" to low voltage DC conversion. Most (all?) will operate fine while plugged in to their AC adapters. The Kindles I've encountered all do as does my Dell Venue 8 Pro tablet (Win8.1). Even my old Sony Clie devices would work fine while charging.
