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 power cord to reach 25 feet and add a 3-way plug, while still being able to store it relatively easily.
Step 1: So here's your laptop cord...
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 cord is the same length as the skinny charging cord... why? Maybe for when the outlet is 5 feet off the ground? couldn't it just hang off the plug (probably violates some code or law... oh well )
I'm doing 3 things, you can choose to do as many you want and you will still have a much awesomer power cord.
1) Shortening the big 120v cord so it wraps around the brick only once.
2) Adding a 3-way plug to the power cord so I can charge when all the outlets are full.
3) lengthening the small charging cord to 20' to reach farther.
