This is a super hack.
I bought a cheap Ikea ribba frame and mounted the Kobo wifi in the frame with a new mount to fit the screen size of the Kobo. I took off the front bezel of the Kobo to allow it to fit flush with the mount. I modified a mini usb connector and chiseled out some of the frame to connect a power cord. You can see a tiny twisted white wire on the left of the image that carries the power to the Kobo.
