Question: What size is the area for the outlet strip?
Document: No more chargers everywhere. My desk finally looks organized. Only thing is the power strip has to be a certain size in order to fit comfortable.
The unit is pretty and sturdy. However it doesn't have a power strip in it at all! The description says "no surge protector", what it should say is "no power strip included". Pricey for just a decorative box.
Awesome quality and perfect size, not too small and not too big for my kitchen counter. Hubby puts his keys, wallet there and charges his cell phone  every night there making it less possible to loose his things for walking out in the mornings. Great organizer! !
I wanted a white color, which is hard to find in stores by me. This works perfect and looks really nice on my white desk. It had a strong odor (paint?) for the first week and a half, but is fine now.What I really like is that the cord plug in/storage is in the back side, and fits a small-ish usb power strip.
We wanted something on the kitchen counter that looked nice and could hide our wires. This definitely fit the bill. The drawer is also nice to put mail in. It is not a full-depth drawer, but for us that is best because the area behind the drawer is open to hide wires, adapters, etc.
We get lots of compliments on this from guests. Its a much more affordable....ahem....copy of Crate and Barrel's charging station.
This recharge station was the answer I was looking for. I purchased several possible solutions but this ended my chase. It contains very nicely in the spacious compartment in the back, the alternatlive cords and plugs fit in the drawer up front that are not conncected to anything else. I am pleased.
This has been great for keeping our chargers organized and in one spot. We took the door thing off the back so it would sit flush on the wall, this would not be a problem if you plug in is higher than the station. In my case it sits right against the plug in. One small thing is the little drawer. I'm always pulling all the way out, it should have something to prevent this.
The Cardinal Recharge Station is exactly as advertised. I immediately cleared up a kitchen counter. We use it every day to charge a variety of  electronics.
I ordered this product to organize a variety of electronics in our kitchen (two cell phones, an iPod, a Kindle, etc) and this looks great on our counter. I do wish it came in a variety of colors (I would've ordered it in black if it came in that color). The price is a bit high, I thought, but it was the most affordable option for what I was looking for.
Answer: The entire back is open. Without having it near to measure, plan on the width of the cabinet, less ~ 1-inch for the combined side boards.  Also, the slide-out drawer is not full depth, so you have 3+inches behind it.  I have a lot of wires/extension cords stuffed behind it, and still able to slide tight agains the wall, hiding all of them (except for the outlet on the wall).  I hope that helps.
