Great way to power your usb hubs if your pc can not handle it. Some hubs with not work with this setup, so try at your own risk.  Lot of people do this with the usb hubs, but I wanted to be able to use the hub without having to have the power attached.

Step 1: What's Needed.

Parts:
1 - usb extender cable
2 - wall phone type solderless jacks.
1 (or more telephone (rj-11) type cables
1 (or more) telephone (rj-11) type extenders.

Tools:
Wire cutters and or wire strippers.
Screw driver
Continuity tester (i.e. https://www.instructables.com/id/Yet-another-continuity-tester/)
or Ohmmeter.

Step 2: Prepare the Ends.

Take the USB extender cable and cut it in half.
Strip the outer insulation so that the 4 internal wires are showing.
Strip a short bit of the insulation of each individual wire.

Step 3: Install Ends and Test.

Attach open wires to terminals on the adapters using lie colors.
Install telephone cable in the ports on the adapters.
Check connections so that wires connect correctly, ( use the pictures to help you.

Step 4: Done.

And now to put it to use. We plan to use our with the network printer that can also be used as a scanner. the network printer box does not support network scanning.  We do not want to move the printer around.  Hence the cable is valuable for that. You still need a regular USB cable to connect to the printer.

Step 5: Usb Power From the Wall.

Step 6: Emergency Usb Condom.

Connecting your phone or other computing device to an unknown usb port could get your device hacked. Protect yourself with a usb condomso data lines do not get connected to a nefarious host while charging. getting an usb extender bable from the dollar store is the easiest way to statr making one.

Step 7: Untested Usb Charger.

Try this one at your own risk. Thinking of experimenting with this charger.
This is just plain fantastic, rated 5* would rate more if possible!!!<br>Have a look at my instructables that I made as well!
Super thanks!
What is the maximum length of the USB cable I can extend?
You probably want to make it as short as possible. In any case it will depend of the what kind of power comes from the power supply and the resistance of the cables to the usb ports. I have seen some systems support longer cables and others that did not.
