This flat MagSafe dock can be mounted on your desk or on your wall using a wall mount. MagSafe can be adjusted to the dock, you can use tape if you want to be extra safe. On the back there is a hole to help you eject the MagSafe Charger if it gets stuck. You can use tape to stick the pug to your desk or wall. There are also screw holes if you want to screw it to your wall. The screw holes are compatible with Ikea Skadis or other wall boards.
My favorites are these reusable microsuction tapes, they provide strong adhesion and can be removed without leaving marks.
