I hope you'll find my idea interesting and useful.
As you know smartphones and tablets consume a lot of power and we have to keep charges, batteries and wires.
Here's my idea of cheap charging station.

Step 1: Tools and Materials
Step 2: Drill
We take IKEA box and drill a hole on one side. For stability stick rubber pads on the bottom of the box.
Step 3: Assembling
Glue the USB hub inside the box and plug power cable.
Then you should glue the hole carefully. After that plug all necessary USB cables.
Take out all cables through the hole in the cork top cover of this box. If you don't plan to dismantle this I recommend to glue the top cover to the box.
I made this distributing construction out of spare plastic cable ties, put it to cover the hole and glued it. If you have any other materials you can do something prettier.
Step 4: Finish
As a result we have a charging station for couple of phones with comfy surface to place them while charging.
Average cost of all materials $65.
