[Galaxy Tab 3 Q&A, Help & Troubleshooting] Super Sam Galaxy:
That sounds like a fantastic way to do it. I was very uneasy about magnets because of two things: the first is that I was afraid they would separate and the other is that I thought I'd need magnets so strong they may damage the tablet. Gorilla gluing them to a case is perfect because it's strong, doesn't damage the tablet, and doesn't require ridiculously strong magnets like I'd need if I had something like a metal plate inside the tablet that the magnets would need to stick to. I wish I'd seen this post a few days ago, because as it turns out I have already started another plan, which I've already ordered the parts for, but I'm strongly considering cancelling my order to give your method a try. The one thing that makes me hesitate is that with the new plan, I've come up with a way to hide the cord, whereas I was unable to think of a way to do this when it's on the fridge.

Here's what I put together: I have a cabinet directly on the left of my stove (as opposed to the fridge which is directly to the right of it). The cabinet starts about a foot and a half off the ground and comes up to about my neck. The idea is to mount it on the cabinet door and hide the cord in the cabinet, and the specifics are as follows. There's no power source inside the cabinet, so I was going to drill an extension cord sized hole in the back base of the cabinet to slip an extension cord into. Then I'd drill another (smaller) hole in the door for the micro USB end of the charging cable. Next, I'd put the power cable together, and it consists of 3 parts. The extension cord, a USB-to-power adapter, and a micro USB to USB flat cable that I've orderd. I ordered a flat one so it can go behind the tablet without being very visible. So once I have cleared a path for the cord and put it together, I'll run the cord from the wall to the hole in the door, and staple it along the edges everywhere in between so it's not in the way. Finally, I'll mount a TPU case on the top part of the door by drilling holes and screwing it in, securing it with hex fasteners on the other side of the door. I've included a simple MS Paint rough draft of what the finished product will look like.

The idea is that it will be mounted on the door, the cords won't be visible, and it will always be connected to a power source (unless I remove it temporarily). I'm not too worried about frying the battery since there are not many instances that would require me to remove it from power so as to rely on the battery. I hate to be so OCD but visible cords are a bit of a bother to me. However, if you have any ideas as to how I may hide them with the method you mentioned I'd be happy to hear them since your method sounds far easier and less destructive, and probably an all around better option if it weren't for those pesky cords! Also, since my tablet hasn't arrived yet I can't check this for myself: (if you have the same tablet) does the Galaxy Tab 3 7.0 have NFC capabilities? I couldn't find anything saying it did, but I couldn't find anything saying it didn't either. If so, I'd put an NFC sticker on the inside of the case and create a set of tasks in Tasker so that when I put it in its home it goes into "Kitchen Mode". Anyway, thanks for all your help and suggestions, and whatever I end up doing I will definitely post a few pics to show it off!
