You can also use it to plug the devices into your PC/MAC so they can charge that was too.
Step 1: Supplies Needed
- something to cut/modify the cardboard
- something to mark with
- something to measure with
- usb hub (doesn't matter if it is 1.1 or 2.0)
- your usb cords
-USB to AC adapter
If your cords are AC adapters you may just want a small power strip and all your ac adapters that you want to charge at the same time
Step 2: Step 1
Step 3: Top Tray
Find the center of the cardboard tray and mark a small hole that big enough for your largest cord to fit through.
Cut out the hole with scissors or your own preferred way of cutting cardboard.
Step 4: Bottom Tray
Then thread the other cords through the top tray and place the tray in the bottom tray. (hopefully is will be a snug fit if your trays are the same size.
Next plug in the USB Hub plug to the USB-to-AC adapter.
Step 6: Plug in Your Devices
Finally plug in all the devices that you want to charge. (I would show you four devices but I'm using my camera phone to take these pictures.)
