Tired of using your laptop in lecture halls with 300+ seats and one outlet... or when all the seats next to the outlets are full? (and you're too lazy to charge your laptop beforehand) You can easily lengthen your Dell NF642 AC Adapter power cord to reach 25 feet and add a 3-way plug, while still being able to store it relatively easily.
A big mess of tangled wires with practically no way to organize things... It's like the laptop companies wanted you to hate them. The thick 120v Dell NF642 AC Adapter cord is the same length as the skinny charging Dell AC Adapter cord... why? Maybe for when the outlet is 5 feet off the ground? couldn't it just hang off the plug.
I'm doing 3 things,you can choose to do as many you want and you will still have a much awesomer laptop ac adapterspower cord.
1) Shortening the big 120v cord so it wraps around the brick only once.
2) Adding a 3-way plug to the Dell NF642 AC Adapter power cord so I can charge when all the outlets are full.
3) lengthening the small charging cord to 20' to reach farther. I think I've seem some laptop plugs with a muli-pronged plug that carry a couple voltages to the laptop, this couldn't be replaced with 2-strand wire.
No turning back now... Notice that one wire is a coated central wire and the other is braiding around that Dell NF642 AC Adapter wire.
Make sure to keep track of your wire polarities at all times! Lamp cord and most Dell AC Adapter power cords have a rough wire and a smooth wire to distinguish between (+) and (-). If unsure, use a multimeter to check for resistance.
Plug everything in and if your laptop starts charging you're not a failure. You now have a great long Dell NF642 AC Adapter cord. If you are a failure, unplug everything immediately, and figure out where you went wrong. Test again after you've spliced the 120v Dell AC Adapter power cord.
